Hey guys i was searching around and i wanted to make a mass sleep spell that will make all units in the area sleep and i've done it. Now the problem, I want when some 1 of the units takes damage to make him to lose the buff. So i copy/pasted the sleep buff and make a custom buff. And then i saw this: (This unit is sleeping; it cannot move, attack, or cast spells. Attacking it will wake it up.). How can a unit wake up when he is attacked when he is made already invulnerable? I don't understand that? Help please
