Toggle: Swain transforms into the form of a raven. During this time, up to 5 lesser ravens strike out at nearby enemies each second, one raven per enemy, dealing 50 / 70 / 90 (+20% of ability power) magic damage. Swain is healed for 20 / 30 / 40 (+12% of ability power) per champion hit and for 8 / 11 / 13 (+3% of ability power) per time he hits a minion or monster. Lesser ravens can't attack the same target again for 1 second. The cost to sustain Ravenous Flock increases by 5 Mana every second.
