You know when your screwed when you roll a miscast, say "Whats the worst that can happen?" blow up your Lord on dragon, cause a panic test to all your chariot riding hero's and shaggoth and they run off the board (Turn 1).
This was 2 editions of fantasy ago if i remember correctly (when heroes riding chariots counted towards Core as well).
PS - Yes, it was a 5 model army in 2k.
Don't, after rolling that final 1 too many, flip out, climb up on the table and jump up and down on your opponent's models screaming 'APOCALYPTIC BARRAGE, MOTHERFUCKER!!!'.
