Pyre of man supposed to last 3 turns. The problem is that he is rather big and occupies 9 squares. When the spell is cast, however, the cursor turns into one square summon tile. If pyre is summon so he covers some enemies (not on entirely free 9-square tiles) he lasts less turns (as long as their are enemies among his feet he looses his turns). Consequently, i have seen pyre going out without even attacking once and 1-2 attacks is norm. Only if i cast him far from enemies he gets 3-turns.
