[Rework Idea]Xerath, the magus ascendant

So i've been playing alot of lately, and i noticed he's pretty much un-approachable all game, and has an easy time shrugging off ganks even without wards.

So the basis of this rework was to move his power that he has all game, and start off slow to own in late game.

Innate passive: Seal on power Xerath has a seal placed on him, as he casts spells, attacks, and puts ranks in his ult, the seal wears away. 0.1% for autos, 0.8% for spell casts, and 15% for ranks in ult.

As the seal wears, xerath's spells and other attributes become more powerful and his model updates. +5% increased spell damage for each 10% Wear on seal +2% increased attack range for each 10% Wear on seal +1% increased movement speed for each 20% Wear on seal +5% max mana and +20% base mana regen for each 15% Wear on seal +5% CC duration on spells for each 20% Wear on seal When Xerath breaks the seal, his model updates again and he gains 30% increased range on his spells.

Q: Arcanopulse 20% reduced damage, same scaling. CD at max rank increased by 0.5 seconds

W: Eye of destruction Empowered slow decays to 30% instead of 10% 25% reduced damage, same scaling.

E: Shocking orb 20% reduced damage, scaling decreases to 30% from 45 range increased to match W

R: Rite of the arcane Ranks in rite of the arcane Wear the seal on xerath by 15% Arcane barrage 10% reduced damage scaling increased to 45% from 43
