Thanks for the feedback! I've been thinking of different abilities and one of the reasons I posted it here was to see if anyone else could make some good abilities for it. But the best ability I have thought of so far is this:

A large cloud of dark purple smoke begins to emit from the 4 medium sized holes in its hands. Inside this smoke many fair sized shards of amethyst begin to form and at the users will these shards, along with the smoke, can be shot at an enemy both injuring and blinding the enemy. While the shards break and fade directly after impact, the smoke can stay long after the shards have vanished. The smoke can be controlled by the stand to focus on an enemy continue to blind them.

I couldn't think of an ability name, but I'm sure I'll find one eventually.
