kolos: Cure spell should be removed from game and modify the dispel spell. this spell should dispel all kind of spell cast by enemy like frenzy, slow, weakness etc.

kolos: whirlwind:

whirlwind attack is suitable with weapon like axe,swords etc

but with bow and crossbow? its weird combo(even in fantasy world)

but Death Angles and diablo can use it

this technique should work only with suitable weapons(axe, blades etc).
