Sivir Spell shield only giving mana back
In an aram game; at first, two attempts to use it against veigar's aoe stun. The shield proc'd and gave me mana for successful use, but I was still stunned. Stopped using it for that, blocked a nidalee and tf's ranged abilities as normal. Late in the game though, the shield once again only gave me mana back while I took full damage from their abilities.
