Hmm...is a timed fuse in theme for fire?
I think so.
Also, a few thoughts from me while I hunt for data:
We found that we can push magic into our weapon and armour, but never actually tried doing it properly; keep that in mind for the next magic-session. Also, getting our actual flight would be good.
We also decrease our own weight for this version of Flight, which allows us to go to greater heights... but things we carry do not get lighter, as we saw with Una just in the last update. Maybe look into that.
Furthermore, I just noticed that Double Cast was a great thing to buy.
Our Thermal Spear has either Burn or Freeze; the latter does 1% Maximum Health damage per turn and reduces the target's ApT to 1 (if it was 1 before, the target is frozen in place).
Burn has the same damage... however, it can be stacked up to three times; which means that a single use of Thermal Spear can already apply two stacks.
We have to experiment on whether we can get extra damage by alternating between fire and ice.
Also, we should save up for Ignition Aura - Burning Plate; the description is a little weird, but it is basically another 10% damage reduction while it is active.
Then we just need to train keeping it active all around us, but only barely above our skin; we get the reduction without setting everything on fire, although the floor around our feet might melt.
My thoughts so far. Please expand.
Oh, also Spell Boost on our sword the moment we can buy it; the spells are our main source of damage and every bit counts.
Speaking of the sword, maybe we should ask Una if she came up with a name by now?
Edit: Actually, one more thing.
We have healing power and we can roughly guess how it runs through our body; try to express it outwards like Ignition Aura for a healing variant?
