ok, a preview not necessarily the final powerset
Cybernetic Shove: Increased melee attack with $KB,with additional electric $DMG. ;
Electrostatic Chaos or Indra's Storm
Heavy Weapons: Rocket is fired and home in on targets.Tap key for additional rockets( I changed a little your idea).
Garuda's descent: I would like to do but is difficult since I don't know a way to put the character flying or jumping in a high level on an attack so it will be strange.
the boosts will be probably Malicious Rog, Machinehead(that I will be probably renaming for Artificial Intelligence), vaporizing-barrier , neuro-poison and vayu's blessing.(I don't know if I will put all this boosts depends if garuda's descent will be in or out of the list)
is it for now
