Ability One: A lightning ball is created at a targeted point grappling any units in the area (With a lightning effect). Instead of the ball pulling the units closer, it spins the units around 180 degrees clockwise, and lets them go (So it spins units 180 degrees from the location, and at the same distance from the lightning ball).
Ability Two: You cast a chain lightning effect that can be targetted on either an enemy or ally and bounces between enemy or ally, and if it hits an ally it heals them, but if it hits an enemy it damages them. The lightning changes colours when it goes to an enemy or ally (Green to ally, red to enemy).
It's a bit cartoonish, and not were warcraft-like in style, but you can fix that. Add a bit of texture and use less blend, to make it more rough. High contrast is also something that is used a lot in warcraft icons.
Overall, the icon looks nice You should just define the sword more, so that it stands out, since right now the sword and mr. Pit Lord kind of blend together a bit. So paint a shadow behind the swords upper part so it overlaps the pit lord. Just like a dark glow. And you can always set that layer to overlay or multiply, since that will probably make it look better good luck!
