Taliyah rock surfing skill might be controlled like sion ult, and she might be a hybrid
I think she will have a rock surfing skill similar to sion ult, a knock up since she trained with Yasuo and (this might be a stretch) she might be a hybrid mage doing physical damage with some ap/ad scaling.
I mean, rocks should do physical damage and it would add a unique aspect to typical mages like how Diana is an ap fighter.
leggit throw ice shards and damage is still magic
AOE spikes coming out of the ground is magic
throws a cleaver at you, deals magic damage
Throws a magic projectile at you, deals physical damage
Throws knifes, magic damage
Grabs you with an anchor, magic damage
burst of energy coming out of her sword, physical damage
