[Implemented] Player_hasSkillEquipped

Ok my fault, I need Player_hasSkillNotEquipped.

I want to define a condition for the potion where it is only used if spirit walk is on cooldown and health < 20% OR health < 20% and spirit walk not equipped. only this way it would work on other classes or before I have spirit walk.

It's like a additional cheat death
If my health is < 25% spirit walk is used, if spirit walk is on cooldown and health < 20% the potion is used and after that the cheat death comes. But often the cheat death comes instant, because the damage incoming is too high. xD And I want spirit walk first, because the cooldown of the potion is longer.
