played more dnd today. we stumbled into a goblin hideout, found our way straight into the miniboss's room, and proceeded to kill him before he even did any damage. it took two player turns. i did 19 damage out of his 27 hitpoints. after he died, we took out everything else in the room with very little trouble. it wouldn't be a stretch to say we had a tougher time during the starting encounter.
needless to say, our dm was astounded and quite furious. he plans to get revenge on us, probably next session.
