There were two different sources of damage. One for 30% current HP damage for all party members, and a different type of damage that was supposed to reduce the HP of the salamander girl by 25%. However the system doesn't work as I thought, and both values were reduced from the party. I removed the additional damage, so it'll only be the 30% current HP damage to the party now.
Oh, so, a sort of collateral damage? That would be cool, and pretty sensible, thanks for explaining. But also, thanks for removing the extra damage, it was more than a little alarming to see a relatively common enemy deal higher damage than certain bosses. (And wow, your reply really came in a lot faster than I expected, not that there's anything bad about it lol)
