Idea for Ryze Rework?

Passive: Spell Gap; For each spell that hits a target for the next 1.5 seconds [stacking upward] the next spell will do an additional 5% + 1% (Per every 500 Mana) damage [Stacking up to 5 times]

Q: Overload; Cooldown goes off of Cooldown each time a spell is cast. Ryze throws a skillshot that detonates at the end of its travel distince or on impact. Causing all marks to blow up dealing damage. Spell Range 600. Travel speed 1650.

Cooldown: 6 50/65/80/95/110 + 20% AP. Mana Cost 50. Mark Explosion Damage= 5% Max Mana.

W: Rune Prison; Charge System {Prison Rune} [2] every 14 [affected by CDR] seconds. Cast time in between .5 seconds. Ryze slams the ground creating a shockwave that goes in a line damaging all enemies and snaring the first champion hit for 1.25 seconds. Minions take 80% damage and champions are marked with a Hex rune, Hex rune activates after being hit by 3 other spells. Hex Rune does damage= 5% of Ryze's Mana. Travel Speed 1800, Distince 800.

Cooldown: 14- CDR% 60/70/80/90/100 + 15% AP Hex Rune Damage= 2.5% Max Mana.

E: Spell Flux?; Charge System {Flux Rune} [4] every 8 [affected by CDR] seconds. Cast time in between .25 seconds. Ryze throws a spell in target direction marking the first target hit. If target is already marked creates a shockwave behind leaving target within 300 range marked as well including origin target. If a minion dies while getting hit with Spell Flux increase the range of shockwave to 600. Skill Range 700. Speed 1550.

Cooldown: 8 - CDR% 65/90/115/140/165 + 25% AP

R: k?; Ryze increases his movement speed and takes reduced damage based on the runes. [5% Movespeed + 10% damage reduction per Rune.] For each rune missing Ryze deals an additional 3% damage and consumes 10% more mana. For the next 3 seconds. *Shifts according to using runes.

Cooldown: 120/100/80

Doing a trail run with these numbers right now. Help me fine tune this if you think this would be a healthier play style for Ryze.

Late game: Six Items.

Seraphs= 80 AP + 1000 Mana + AP=3% max mana Morello= 100AP + 400 Mana RoA= 100AP + 500 Mana + 500 HP Void Staff= 80 AP Rabadon's = 120 AP + 35% Max AP (before this passive) Boots 10% CDR

Not including runes and masteries. Sticking to ryze's current Mana pool. 1250. 1250+1000+400+500=3150/500= 6.3% for passive. +5=11.3 3150x.025= 78.75 W damage for Hex. 3150x.05= 157.5 Q damage for Mark. 3150x.03=94.5AP AP= 80+100+100+80+120+94.5(mana AP)= 574.5 574.5 x 1.35= 775.575 AP.

Assuming you stand in a brush that is not warded lets see the damage output from a; also under the assumption that they are taking 65% of the full damage.

Q W Q E Q= 294+265+355+521+415+78+157=2085 x .65= 1355.25 Damage

R Q W Q E Q= Under conditions of starting with 6 runes.

294+273+376+568+465+78+157= 2211 x.65= 1437.15 Damage

Remember that ALL 3 damaging skills are skillshots.

Only W bypasses Windwall and Unbreakable Shield.
