I can do things others can't...
Bet would be that the spell - like the Mass Resist (Divine Energy Resistance) from the Radiant Servant for a Sacred Fist, did not have something checking for Warlock levels when it was copied over from one of the other existing classes. Wizard for example, works fine. Should be a quick fix by a Dev.Warlock's fog cloud spell should last 1m32s but it only last 1 second before it vanishes. (This video was it cast in the wilderness, so no reaper scaling or other thing effecting it)
