Zaltz - The Swamps Avenger

Ok, so this is the first time I have done anything along the lines of Champion Creation, and any feedback would really be appreciated. Let's get started.

Name: Zalts Resource: Aymtrock Auto range: 125

Resource bar: Each time Zalts auto attacks, he gains 2 Aymtrock. At max Aymtrock (20) the next damaging SPELL will be reduced by 20%. That goes for any other amount of Aymtrock. If he has 15 it will be reduced by 15%, likewise for every other amount.

Passive: Vengeance: Each time Zalts takes physical damage, it is stored until Zalts auto attacks, which expends all the stored damage.The auto attack can deal an extra ((current level x6) ex. (14x6=84)(84 damage)) damage. Taking physical damage adds 1 stack, and at 6 stacks you reach the maximum amount of extra damage for that level. So if you had 3 stacks at level 14, you would deal 42 extra damage. After the bonus damage is dealt, it takes 3 seconds for this effect to happen again. You cannot gain stacks while this is on cooldown.

Q: Preying Eyes: Zalts dashes in a direction (200 range) Any enemies he comes into contact with take (50,65,80,95,110 + 50% AP) magic damage. If an enemy is hit Zalts gains 10% attack speed. This ability has a cooldown of (7,7,6,6,5 seconds) seconds.

W: Feet of the Aymtrock: Zalts cannot be hit by target abilities or auto attacks for (2,3,4,4,5) seconds, but he takes an extra 10% damage from everything else and CC durations are 10% longer, for the duration of this spell. The cooldown is (17,16,15,14,13) seconds. Cooldown does not start until effect wears off. The CC duration debuff does not effect ultimate.

E: Leap of the Frogmen: Zalts crouches low, then launches in any direction (500 range). If he hits an enemy, he will travel an extra 200 range. This does not stack, as soon as he hits the enemy the extra range resets, so he can only go 200 range past his last target. This range extra can be triggered (2,2,3,3,4) times. Zalts can cancel his dash at any time, knocking up nearby enemies within auto attack range (125) for .5 a second at all ranks. The cooldown is (20,19,18,17,16) Auto attacks reduce the cooldown by 1 second.

R: Concealed Redemption: Most of Zalts stats are increased for (5,7,9) seconds. AP and AD by 30,50,70 Movespeed by 25%, 25%, 25% Resists by 20,30,40 Attack speed maxxed, but decays over duration Health regen doubled Crit chance increased by 10%, 20%, 30% And armorpen increased by 10%, 15%, 20% In this time Zalts is silenced.

Base stat: 540 Hp 75 AD .79 atck speed 360 movespeed 32 armor 29 magic resist Don't really know how much it increases by each level

Thank you so much for reading, and any feedback is appreciated!
