What's the dumbest thing you've done in combat?

My smart ass, on way past my first playthrough, thought a good strategy for my War Domain Cleric would be to 'Buff with Bless, then pop Divine Favor for extra damage'. Which I did, and wondered for a few seconds where the hell my Bless went.

Two spell slots, down and out. And to round off the whole thing, every Goblin Archer decides they're gonna rail me with arrows, or which my 20 AC War Domain Cleric avoided none of, and lost concentration on Divine Favor.

I'm good at this game, I swear 😂😭
