Siege-based champion

Was thinking about this for awhile, probably would be OP with my current stats but whatevs.

Would be either a ranged carry or something similar, I could see with its current abilities functioning as a decent support as well. But its a must-have on siege comps. Has long range and is a real threat to those hugging turrets. Could be build AP or AD

(no name) the siege master.

Resource: Materials, starts at 400, mana pots are replaced with resource kits which instantly give materials. Items that would normally give max mana instead give 10% of that bonus to materials (ex something that gives +500 mana would give 50 materials.)

Passive: Turret Buster

Has 10 armor pen on turrets. OR deals a bonus 2% of turret current(or max) health on hit.(would end up being +40 damage at max health)

Q: Blasting arrows

Passive: Killing a minion or champion shatters their armor and returns 1(+ number of blasted stacks) materials.

Toggle: Arrows consume 2 materials / auto attack. They deal +5/10/15/20/25 +10% AP to all units within the blast radius (125 range). The enemy hit by the arrow receives 2 stacks of Blasted Armor, reducing his armor by 1 per stack, up to 50 stacks, the stacks wear off after 6 seconds (could be longer maybe). Enemies caught in the blast radius receive 1 stack.

W: Flaming Barrage

(25 materials) (700 range)(5 charges) Rapidly fires a flaming arrow at the target location dealing 40/45/60/75/90 (+25% AD) (+10% AP)(reduced damage on enemies recently hit) and applies flaming ground in a 50 unit circle around the landing location of the arrow for 3 seconds. Flaming ground deals 5/10/15/20/25 (+20% AP) per second to units standing on the area. Units directly hit by the arrow also recieve 2/4/6/8/10 (+5% AP) damage per second for 10 seconds. Can store up to 5 arrows and stores another arrow every 18/16/14/12/10 seconds. Arrows arc over everything between itself and its target so they won't be blocked by minion waves.

E: Fortify

(50% of current materials) Consumes 50% of current materials to fortify an ally unit or turret which shields for 50/100/150/200/250 (+ 2 * materials consumed) and grants bonus 4/8/12/16/20 Armor and Magic resist.

R: Siege Engine

(75% of current materials) (700 auto attack range) (1500 cannon ball range) (200 explosion range) Created a siege engine that has 200/400/600 health and has a separate material reserve equal to the amount of materials invested. Fires basic attacks at 1.00/1.50/2.00 attack speed that deal damage based on how close the target is (75 damage at 200 range, down to 25 damage at 700 range) and consume 2 material each. Can also fire large cannon balls that consume 100 materials each and deal 250/300/350 damage. If destroyed it explodes dealing 200/300/400 (+100% AP) damage to all units in the blast radius.
