Which is what makes her so hard to fit inside a single character. She can do pretty much ANYTHING! Even change the entire world(s).
Some ideas:
Passive skill (or when blocking): bullets/projectiles against her have a chance to either pass through or reflect back but now they target enemies instead of players.
Hex Bolt (main ranged attack with random effect)
Reverse Gravity ("break" move that throws nearby enemies upwards).
Nightmare Hex (enemy becomes aggressive against all, for a while)
Transmute to Crate (if enemy is killed while in crate form, may contain item inside).
Magic Circle (place a trap that triggers when enemies touch it, but with random effect, like Blackheart's Inferno. It's better than Hex Bolt, but you must lure enemies to it).
Hex Sphere (summon a slowly moving ball of chaotic energy that randomly Hexes enemies near it with random effects like fire, lightning, ice, poison, etc. Not as potent as a Hex Bolt, but works independent of her, and you may have multiple ones active).
Alter Reality (create a temporary wall, object or obstacle, low enough to jump above)
Unending Pit (creates a hole on the ground, enemies who fall reappear seconds later, high above ground)
Dimension Door (create a tear in space/reality that when touched teleports her, another player or an enemy, to a random position; enemies can take damage or come back disoriented/stunned. This could also be a passive skill against enemies doing melee attacks)
Warp Reality (she looses control and whole screen flashes, changes colors, background, etc, enemies are severely slowed and weakened)
