FOH in TG

hi all i wanna know how can i use fireofhell in tg cuz when i click the stake it doesnt hit but i see other doing FOH..........after anwsering that question tell me whatz better exp in tg fire circle or FOH ^^

use scarecrow or how its called

You need a target to use FOH in TG. So, take another char there, put him in front of a stake and attack him, this should make you attack 3 stakes with FOH.
FOH makes less damage than Fire Circle, but it's much faster, so you should get more exp with FOH.
The problem is, though, that you will stop attacking when your target char disconnects.
