Zaiden, this characters real name, knows a kark load of usually off limits powers. Its not necessarily whats unavailable, rather how you play with them when you learn em. In the begining i was told that Force Cloak is generally one of the most abused abilities, but since i first began its uses everyone has seen that the fun of it all is my intent, a victory second.
Go ahead, learn Force Storm or Teleportation or Phase, just use them in a way you would find fun to go against.
Ie:
Phase. Instead of simply phasing through everything that comes towards someone, they could phase through one then dodge another.
Teleportation. Dont use this sort of thing in battle, unless with the greatest care. As said about my own Cloak, if i used teleportation it would most likely be in the form of an overly taxing dodge.
Etc
So yeah, pretty much any power is accepted. (Zaiden actually created a form, Umbrakinesis)
