On a side note, we have yet to steal that lake of mercury in the Plane of Earth. There were even some nice fiends guarding it.

I was actually thinking about the air-supply for the Kingdom of the Moon.

...

That's our goal, right? Becoming King of the Moon?

I sometimes loose track of what we are doing.

You're right, definitely a failing on our part. Stealing a lake is a good start... Can we steal a mountain? I've had my eye on the Giant's Lance forever. The Arryns don't deserve it.

My plan to reduce Casterly Rock to a crater and steal all of the left over gold kinda counts for looting a geographical feature.

Ah, here it is.

Yes, we shall make Moon our orbital weapon platform.
A scaled-up railgun of Azel's should do.

Listen up you primitive screw heads! This is my

Magitek Railgun
Warning: Contains Math, Mad Science and Hubris, Keep Away From Children Under Level 3

1. Physics
First thing first, we need to find out how much 1 point of lightning damage is in real world units. To find this out, we use 5 feet long iron pole with a diameter of 1 inch.
π * ( 0.5 in )² = 0.79 in²
0.79 in² * 5 ft = 776.7468 cm³
776.7468 cm³ * 7.847 g / cm³ (densitiy of iron) = 6.1161 kg

According to this, it will need roughly 550 kw/h of electricity to melt a ton of raw iron.
550 kw/h * 0.0061161 = 3.3639 kw/h
This would completely liquefy our iron pole.

Said pole has Hardness 10 and 30 Hitpoints, for a total of 40 electricity damage to completely destroy it. D&D says that electricity and fire usually do half damage against objects, but halving electricity damage to iron seems just as sane as halving that of fire against wood.

Let's now eliminate the time dimension by converting to MegaJoule and get the final power.
1 kw/h = 3.6 MJ
3.3639 kw/h * 3.6 = 12.11 MJ
12.11 MJ / 40 ED = 302.75 kJ / ED

Since this damage is done entirely by Joule Heating, we can now calculate the actual current.
Energy = Volt * Ampere = Volt² / Resistance
Resistance = Resistivity * Length / Crosssection
Resistivity of iron = 9.71×10−8​

Therefore:
9.71×10−8​ * 1.524 m (length in a sane unit) / 5.096764x10-4​ m² = 2.90342x10-4​ Ohm
SqrRoot( 302.75 kJ * 2.90342x10-4​ Ohm ) = 296.4811 V
302.75 kJ / 296.4811 V = 1.0211 A

Given that the energy scales linearly with every ED and assuming that the voltage of a electricity attack remains static, we can assume that Ampere grow linearly with ED, giving us:
A(x) = A(1) * x

Now let's calculate what we get for our buck.

Normally a railgun has the problem with the very low inductivity of the the rails requiring tremendous amounts of energy to launch a projectile. This is a simple result of no coiled wire being able to withstand the forces of the launch. The projectile would destroy the rail before it has even reached the end of the barrel.

However, this isn't Real Life, but D&D and we are cheating bastards.
By making the rails into Adamantine coils which are fixed into place with a Wall of Force, we can get a optimized setup that can easily withstand the forces of firing. While regular Wall of Force seems not up to the task, Riverine is proof that the effect can be used to make nigh indestructible materials. Pricey, but worth it.
We thus use Adamantine wire around a iron core and encase everything in a Wall of Force effect, except for thin Adamantine contacts in the barrel, which allow the projectile to close the circuit. To make the whole thing even sturdier, we liberally apply Harden to the setup.

The inductivity of a coil is given by:
L = µ0​ * µ * Coils² * Crosssection / Length
We assume an average of 5000 coils per meter of the coil, a crossection of 25 cm² and a length of one meter. Due to the length of the coil changing as the projectile moves through it, the rail isn't uniform if we want a constant inductivity, which is preferable for a uniform acceleration.
L = (4πx10-7​) * 5000 * 5000² * 0.0025 m² / 1m
L = 392.6991 H

I won't go into too much detail of railgun design, since my browser history is already questionable enough, but Wikipedia supplies a simple formula:
F = L * I² / 2

Which gives us:
(1.0211 A)^2 * ED^2 * 392.6991 H / 2 = F
F = ED² * 204.7229 N / ED²

The final energy of the projectile is thus given by:
ED² * 204.7229 N / ED² * Barrel Length = x Joule

2. Costs
First, the rails. We assume that the weight of the coils per cm³ is the same as iron.
π * ( 2.5 cm )² = 19.634954 cm²
19.634954 cm² * 100 cm = 1963.4954 cm³
1963.4954 cm³ * 7.847 g / cm³ (densitiy of iron) = 15.407,5485 kg = ~34 pounds

Since the most weight comes actually from the iron core, not the Adamantine-Riverine bastardization around it, we will assume that we only have to pay for 20 pounds of material, the rest being dirt cheap iron. A chain shirt weighs 40 pounds, so we will assume that the material value of it will cover the cost for two parallel rails per meter of their length.
16,000 GP (Riverine) + 10,000 GP (Adamantine) = 26,000 GP per meter = 5,200 IM per meter

Turns out WMDs don't come cheap and we haven't even started on spells.

We can safely ignore Harden, since that is only cast at the rails once and doesn't need to be enchanted into the gun itself. However, we do need spellwork to make sure the gun doesn't break down after a few shots due to overheating or wear. The latter is covered for the rails themselves, but unless we want to shell out even more money to build the whole carriage out of hideously expensive materials, it's better to add Make Whole.
Make Whole: 1800 GP (Command Activated) * 2 (Spell Level) * 3 (Caster Level) = 10,800 GP = 1,080 IM -> 810 IM (Lya Price)

For overheating, we will use Chill Metal, which explicitly is capable of negating heat damage.
Chill Metal: 1800 GP (Command Activated) * 2 (Spell Level) * 3 (Caster Level) = 10,800 GP = 1,080 IM -> 810 IM (Lya Price)

Finally, we need energy. Ironically enough, we get the best ratio of ED / GP by the lowly Shocking Grasp. To get half-way regular values, we will assume a basic "Power Unit" of 4d6 ED, which we average out to 14 ED. Each unit costs:
Power Unit / Shocking Grasp: 1800 GP (Command Activated) * 1 (Spell Level) * 4 (Caster Level) = 7,200 GP = 720 IM -> 540 IM (Lya Price)

Which gives us a final table of:
Part GP IM Lya
Rails (per meter) 26,000 GP 5,200 IM 5,200 IM
Make Whole 10,800 GP 1,080 IM 810 IM
Chill Metal 10,800 GP 1,080 IM 810 IM
Power Unit (per 14 ED) 7,200 GP 720 IM 540 IM
3. Final Design
Now we plug everything together. For the final calculation of total kinetic energy of the projectile, we will assume a energy loss of 25% during acceleration. We will use a 2m long rail and 20 PU = 280 ED as the power source, while firing a 20kg projectile.

Thus we get:
(420 ED)² * 204.7229 N / ED² * 2m * 0.75 (Energy Loss) =24.0754 MJ

Punching this into the kinetic energy formula, we get our velocity:
SqrRoot( 24.0754 MJ * 2 / 20kg) = 1551.63 m/s

D&D is slightly crazy with falling object damage. A 20kg = ~44 lb projectile would need to travel 40ft per round to do 1d6 of damage. This is pretty bogus, but let's roll with it. We will assume that the projectile has lost 50% of its speed by the time it hits the target.
50 ft / 6s = 2.032 m/s
1551.63 m/s * 0.5 (Speed Loss) / 2.032 m/s = ~ 382d6 of damage -> average of 1337 HP on a direct hit

Total Cost:
Materials: 10,400 IM
Crafting Materials: 12,420 IM
Time in Days: 62.1
The face of Tywin Lannister when we shell Casterly Rock into rubble: Priceless

4. Ammunition
Due to the forces involved, the projectile has to withstand quite some punishment. Regular steel shells will melt after a while, making them unsuitable for long range fire. So these shells are only really useful for close engagements.

However, there are other options:
Adamantine Tipped(AT) - Directly mitigates the problems by making the tip more sturdy, but it will melt all the same given a few kilometers of flight and once the Adamantine is gone, the steel will evaporate immediately.

Adamantine Mantled(AM) - Unlike the version with just a tip from Adamantine, this one will last a lot longer, but obviously require more Adamantine.

Adamantine Tipped Flat Top Shell (AT-FT) - By making the tip of the shell into a flat surface, we are actually improving the air resistance of the shell. The tip will take quite a bit of punishment, but push the air out of the way and form a vacuum bubble around the shell, which massively cuts down on drag and friction. Also useful for underwater use.

Riverine Tipped Flat Top Shell (RT-FT) - Basically the same as AT-FT, but since Riverine flat out no-sells damage, the melting problem disappears entirely. Obviously a pricey option.

Steel Cannister (SC) - The shell is designed to break apart from drag shortly after launch, releasing shrapnel. Nice to clean up large groups near the gun.

Adamantine Cannister (AC) - Basically the same as above, but by using Adamantine instead of steel, we can extend the distance the shell travels before breaking apart, thus allowing shrapnel bombardments of long range targets.

Before somebody asks, no, we can't fire Wildfyre or other chemically non-inert stuff with this. It would go up in the barrel once the electricity is applied.
However, since the thing is just accelerating metal really, really fast, most of the common defenses against long range strikes become ineffective against it. No SR, no wards, no AM shielding, no nothing.

It's just the wrath of an angry dragon, delivered as a half molten chunk of hyper-sonic death.

If it takes in ambient magic and radiates something else then that's a pretty weak argument considering the state of ambient magic for the past few hundred years.

What are a few months compared to a few thousand years?
And in Hell they absolutely were allowed to level and grow their skills. Devils are competent and at war, remember? These Erinye have seen millennia of battle, fought in almost every environment imaginable, and have certainly been seeking better ways to fight all the while. They chose martial power and therefore are Erinyes.
Nowhere has it been said that Hell keeps its devils weak or stops them from learning certain fighting styles.
There is zero reason for them to level from killing a few mutants if thousands of years of fighting demons didn't.

The minotaur levelling makes sense if you ignore ECL rules (I would have started them with lowered BaB and then required experience or training to raise it, like Rhaella. As DP didn't do that then of course years of training should bring a level or two). But Erinyes levelling from a few minor fights like B-party newbies?
Makes no sense. They're already 10 HD!

If they want to change, I'm for retraining them. Or maybe getting a Paladin Creature template eventually.

Take a step back, why does it make any sense that any Devils thousands of years old don't have class levels or a stronger form?

If the claim is that they've been Erinyes for all that time then it is absolutely ridiculous for them not to have advanced even through the sheer weight of existence, let alone the constant fighting.

Part MMCDXXXIII: Duty of the Damned
  • Threadmarks
    • Duty of the Damned​

    Twenty-Fifth Day of the Sixth Month 293 AC

    "It seems our foe's reach grows longer, or mayhap only more desperate!" you shout, pointing behind you ostensibly for Malarys' benefit though the magelord had heard Mereth's warning as clearly as you had.

    He takes a moment to take stock of the circumstances, though that too is mummery, then calls to the dead: "Ride on, ride north, the road is before you and only peril behind you! We will make an end of this!"

    Disturbingly the caravan master's voice spills out from the lips of a girl that had been riding not far behind you, though 'she' gives no indication that anything odd is happening: "How can you fight so many? I hear..."

    "Leave matters of sorcery for sorcerers to deal with. Your task is to get the children to safety, not fight their enemies," you reply even as you wheel your conjured mount about, swift as jumping shadows.

    Thankfully it seems you had judged them rightly, the hidden power of the curse compels them far deeper than the lie they 'live'. Ride off they do though it makes little sense to leave two men, mages though they be, to face the storm of flame and fury bearing down upon you. And so you must now face them, though far indeed from alone you are.

    The hounds spill out from the road like a river overflowing its banks, a swirling mass of hate and flame above which you can glimpse the ornate helms of dragonsteel, behind which eyes like accursed embers shine, as they ride steeds of dread by fel pacts bound to earth, six warriors of old arisen from the pyres of an age.


    At their head there rides one mightier in standing and in strength, his silver hair still wavering like a tattered banner behind him, his eyes as pits of empty might set into a grinning skull. The beast he rides so bright of thrice-damned majesty that its hoof-prints sear the road where it walks, even when the Doom itself could not mark it.


    So does he speak in a voice as as bitter ash and biting wind: "Surrender the boy! You have no right to him! No right to take him even further on a path doomed from the first step!"

    "And who are you to take him in your charge?" Dany calls out in challenge even as the others array behind you or above, ready to fight or to defend. "By what right to you deny him rest as you have been denied?"

    The question seems to enrage the dark champion for he rips a javelin from his saddle and hurls it at your sister with strength far beyond that of any living man, but to your relief she swerves aside with the grace and swiftness of her diminutive form.

    "Are we then to count your blows as words, thy wrath for reason to substitute?" she asks again, though for yourself you would see this thing cast down to dust for even daring to try to harm her.

    "The boy should be with his father, not doing the bidding of a treacherous goddess in the service of thieves!" the master of the fel hunt booms across the barren lands.

    "What have we stolen?" Garin interjects, but the thing pays him no mind, perhaps not counting him worthy of exchanging words, and so you echo the question in turn.

    "It is not what you have stolen but what you aim to, get of a Harlot Goddess." The answer is heavy with the venom of ages stirred anew. "I know you seek to rob Lyceos that you may build your mongrel realm upon its bones!"

    You cannot help but wonder how he knows. Why is he even here riding down your charges so far from the city where he must have arisen to unlife? Yet at the same time you can find little softness in your heart for one who carries such senseless pride into the grave and beyond. What purpose that Valyria's treasures should languish in its tomb?

    What do you do?

    [] Try to turn the accursed warrior from his path, or at least learn something from him before battle begins in earnest
    -[] Write in

    [] Strike now, let flame and sorcery give them the rest they would deny to others
    -[] Write in battle plan

    [] Offer a challenge by champion
    -[] Write in terms and proposal

    [] Write in

    OOC: Unfortunately that's the best picture of a death knight on a nightmare I could find. I really like the aesthetics, but the resolution is a little disappointing.
