Amurtek, One with the Sea

Hi again! So I have multiple champion ideas sitting on a shelf, so today I'm sharing with the community. Obviously, these are amateur ideas for creative purposes so feedback is helpful, regardless, here's Amurtek!

Amurtek, one with the sea Tank, From the Guardian Sea Primary roles : Top (maybe support)

(Passive) - Seas embrace - Cooldown (6 seconds out of combat) Amurtek whips his internal current, giving himself increased resistance from ranged auto attacks, this ability is put on cooldown when Amurtek is hit by a spell, melee attack or ability.

(Q) From the depths - cooldown (16/14/12/10/8) Base damage (70/90/110/130/150 + .25 ap ratio) range (900 units) Amurtek impacts the ground causing a fissure in a line, stopping at the first unit hit, at the end of the cast range, the projectile ruptures and knocks enemy champions back a short distance. If a champion is hit, a pool of water is left behind them.

(W) Tidal command - cooldown (24/22/20/18/16) Base damage (50/80/110/140/170 + .50 armor) range (650 units) Amurtek slams his arms down in front of him, leaving a pool of water behind for every champion hit.

(E) Receding Tide - cooldown (16 seconds all ranks) Base damage (none) range (1000 units) Amurtek manifests under target pool within range, once a pool is used, it dissipates.

(R) Engulf the Shore - Cooldown (180/160/140) Base damage (none) range (750 units in a cone) Amurtek opens his gaping maw, intercepting all projectiles and redirecting them to himself for 4 seconds, during this channel, Amurtek gains (35/50/65%) damage resistance.
