Soul flare failed

[dirtdancer]

Sometimes I cast soul flare in dungeon but it failed to activate. Is there any prerequisite to successfully cast it?

Soul flare and soulburn gives everyone debuff that prevents its activation for certain amount of time. If some other warden in your group uses soul flare or some warlock uses soulburn before you then your SF will fail to activate unless you wait for the debuff to disappear.

Another thing to note is warlocks with VT badge running time distortion.  VT badge enhanced time distortion cuts off part of the cool down timer on skills that can't be reset so if you had a VT badge warlock stick their thrall on you then use time distortion your soul flare will come off cool down with about 30 seconds still left on the debuff that prevents you from using it again.
