Can I zig zag a wall of fire in front of T6, T5 and T4 (length is not a problem 60'), putting all of the trolls on thy "hot side?" Making sure we're all on the "not hot side," seems optimal.
Assuming that's OK. I'll cast wall of fire (by using the lyre) :
DC 18 DEX save. 18 damage half if save made.
