Oh she has far more than that.
Her hut can absorb essense as it walks around, and drain it from enemies which on stream they said it can drain attack power but its not in the patch notes on the website. It then uses that essense to heal her or if she has items that use stacks, it stacks them for her.
Her first ability, besides firing in an assortment of directions with it's main damage coming from her witch fire. But it has various random elemental trails. One is wind and boosts your ally movement speeds, one looks like a mushroom trail that boosts defence, an ice trail that slows enemies, and a sludge trail that silences them.
Her potions use five random ingredients, with eye of newt, dragon scale, and wolf tooth as the ingredients. Eye of newt adds more power, dragon scale slows movement speed, and wolf tooth reduces attack speed and power. The potion color changes based on which ingredient has the majority.
Her mortar, NOT a cauldron, can be hopped into for defense and she makes an explosion that damages enemies and sends her flying.
Her ult allows her to go into her hut, and fire off four massive blasts of witch fire, which upon connecting with the enemy and ground, CHASES the enemy around as a ring of fire.
And thats not counting her connections with nature and her potential of possibly controlling day, night, and the sun.
