So I've been reading over all your thoughts, and as always I love the discussion. There are a few minor things that I just want to make sure you have fair knowledge of.
Edit: I do have some concerns about rate of fire vs rate of kills, though. Arcthunder is strong and will certainly mulch any bandit it hits, but Ryza has to build that whole feedback loop each shot, and thus give the Bandits both time to react, and time to close distance and start attacking in melee after the first dies. It might be worth making Elthunder the default as it only takes one loop, and swap to Thunder if any bandits close to melee range.
I don't actually have a speed mechanic implemented, so using Thunder rather than Arc or Elthunder is not mechanically different. The only reason you all might need to downgrade a spell is if, for some reason, you were deprived of your tablets, or if some story reason came up (training exercise, not wanting to hurt someone too badly, or something like that).
For example, had Ryza failed the roll to think to grab Thunder's Cry, she'd be stuck with Elthunder unless she wanted to give up the initiative to go and grab it.
I agree, but I would suggest that protective anger-shifting might be a good idea if something goes wrong and any bandits get into melee range, or Ryza gets injured. Ryza in heart form is a glass cannon. Depending on how things go, she might need to become a tank.
Would you be willing to add something to that effect to your plan?
Dragon-form is always lurking in the background, and short of some sort of instant-death attack or ambush (which I've certainly not created here, if I ever do at all,) or fighting without her dragonstone (which she will never willingly do), Ryza will always have that split-second of knowing she's about to die, her dragon reacting, and transforming.
Mechanically, if a roll goes really bad, I've had a result that's something along the lines of "Ryza is badly wounded and instinctively transforms." Should she then lose
that combat, there'd be a chance she'd die, but that's never happened yet.
There would be consequences that would come afterwards, but I don't want a single bad set of rolls to kill off Ryza.
EDIT:
especially since few of these guys will have Strong Dice, meaning that Ryza gets two autos onto them. The Thief in particular is going to have a very bad day.
Actually, none of them have strong dice. The bandit leader's not a character, just a slightly-above-average mook. If he did have strong dice, though, Ryza would only get 1 auto success in heart form.
