Sivir E (Spell Shield)
I'm not quite sure if this is intended or not, but when playing Sivir against a Gangplank, when using a spell shield against Gangplank's Q he able to proc his damage and hurt me but I am able to retrieve the mana as if I blocked that skill. I tested this numerous of times and still has to effect of hurting me and I get mana back. I'm unsure if this is a bug or intended.
