Its just an idea that popped out of my head, what do you guys think?
People would say OP I guess but its just giving him some sustain due to his shield is not very durable, so that vamp could be taken easily.
Explanation
Basically, what I propose is while your shield is active, all your abilities (not including passive) gain a 5/8/12/17/20% spell vamp while on, due to his high cooldowns and this not including passive, it wouldn't be like an OP buff.
If you liked it, please upvote and take it to the op so mods can see it! C:
