Round table

So, in the second screenshot, it no longer mattered, the battle would have been won regardless. I obviously didn't transfer the breastplate. It's just possible that this could have been done earlier in the game. The AI's spellcasting is the only thing that decides the outcome here, as they switch from attacking one lizard to attacking the golems after not finishing off the lizard. In the third screenshot, the situation is already decided. A stack of weak units is killed, then in the next round, the weak units kill the defender, and a gargoyle takes its place. This means there's one more shot from the gremlins. As a result, a full stack and some single units remain, and we still have a live defender.
P.S. I have another idea.
