The skills we have so far are as they have leaked are:
All skills scale with AD and not AP
Passive: Gain shield and heal power by 0.5 of your critical strike
Q: You heal an ally and your next attack deals bonus AD damage equal to the amount of heal you did
W: Create ripple on the ground sucking in skillshots and autoattacks but allies can fall in and take damage
E: Dash forward, shield an ally and damage an enemy
R: You dash three times, each dash gives you increased critical strike, dashing on an ally heals them for the amount of damage you would deal, dashing to an enemy damages them. This can apply on-hit-effects.
