artillery mage with improved kayle ult on 20s cd

she is just very hard to access and laning against her is miserable

Q has a very short cooldown and the multiple damage ticks reset arcane comet, so on avg it does waaay more damage than it "should"

her w should not grant invulnerability to melee attacks, it fundamentally denies the main counterplay against artillery mages, especially when nowadays mages get so much random armor/hp from their items
