Critical Bite is a node at the far right end of the Beastmaster tree. It says aspect of the lynx grants you life leech on crit. But it’s confusing because Aspect of the Lynx applies to minions, too. Thanks for the help!
It’s a modifier to the aspect. If you crit, you leech, if your minions crit, your minions leech.
Thanks for answering! That’s how I hoped it worked.
