Kindred's passive
So if Kindred successfully kills (or Assists) the target that lamb's hunting. Kindred's permanently gets 1.25% Current Health damage.
After a successful hunt, Lamb cannot hunt the same champion for 4 minutes.
I hope riot has plenty of ways to control the pacing of the Hunt mechanic. Otherwise a Frenzied match could result into 5 hunts every 4 minutes. (however unlikely) that's Lamb could receive a lot of Health shred, if she get's Snowballing.
