And i am pretty sure you spend too much time here (np though, rented a boat now) and not enough in game.
Am using the skel key 99% of the time now and seen that thing happen an handful of times and ONLY when both troops survived first hit and the LAST get finished by the extra 5 damage that btw happen at the very end, almost delayed seem sometimes.
However, if with enough tears over nothing we can get the skel key buffed (1:1 as damage boost would be better) and why not? maybe also a “empowered” for egg thief i wont cry x sure, so feel free to go on lmao.
Beside a little use of common sense tell me it work as intended, the extra turn is part of the base spell so only make sense if work only with it.
Well, sailing for another dock now, hf.
