As for oyur suggestion...did you mean "castling"?

Anyways, the idea of applying a mark, blocking the next damage and then stun may be a bit...I don't know how to say, but that system can be "troll" maybe if the target is a tank or too aggressive. It's yes protecting, but not in the chess-way, since castling is a secured move before an enemy attacks.

That's why I made a suggestion of changing it to a more Lee-Sin style move, where Chester dashes to the target, grant bonus stats to himself and target, and maybe taunt nearby enemies for a second or two...
