Hale, Ward of Demacia
Hale is a grizzled veteran of the battlefield, having fought beside Garen and Prince Jarvan IV in many battles. He specializes in protecting his Prince, using his unique ability to store hostile energy and use it offensively.
Passive - Prevent 3/5/10 of all damage dealt to Hale. When the damage prevented reaches 20% of Hale's total health, your next attack will deal the amount of said prevented damage. (To clarify, it doesn't keep building up, it is expended upon proc)
Q- Barricade: Hale throws energy onto an ally, briefly lending them his vigor, 3/4/6/8/10% of his maximum health for 2/2.5/3/3.5/4 seconds. The health is removed after the buff goes away.
W - Redirect: Hale erects a magical barrier between himself and his enemy. First cast determines placement of the barrier, second cast determines the angle of the barrier. Enemy skillshots bounce off of the barrier depending on which way it is facing. The skillshots can still hit Hale's teammates, but are also able to hit enemy champions for 30% reduced damage. On hit effects are still applied to Hale and are lost upon bouncing off of the barrier.
E - Smokeless and Mirrors: Hale places a small barrier on the ground. Two casts as before, one for placement and another for direction. Allies may hit the barrier with skillshots to redirect them. The skillshots lose on hit affect, but the mirror shatters and deals damage around it (while still reflecting the skillshot)
R _ Return to Sender: Hale summons all of his magical might and absorbs all incoming hostile energy for 1/1.75/2.5 second while taking 30/35/40% less damage. Upon second cast or after 3 seconds, Hale unleashes the energy back at his enemies in a line. The damage is not reduced.
's or 
's ultimate. The main difference I can see so far is that the return damage is returned as a burst in a line. This sounds like more of a pointed burst (which could be useful for targeting squishies) rather than just an AOE blast. I would need to ask questions to understand the rest of it. For instance, is a taunt involved, or is Hale just soaking up the damage that happens to be fired at him? In the former case, it would be much like Gallio's ult and the idea would be to jump in the middle of mayhem to absorb damage. If the latter is the case, I suppose the strategy would be to trigger it when you predict a lot of incoming damage to Hale? I would be interested in some clarification so I can understand it better.
, for example).
's in order to catch the projectile or reposition for another shot, the point would be less about redirect incoming or outgoing damage and more about playing catch and fire with the projectile.
