Invigorated is part of a chain of skills in the Juggernaut Skill Tree, all focusing on improving [[Health Globes]], their drop rate, a special strength bonus and the amount of hp health healed by them. Barbarians that are on the Juggernaut build will almost never run out of Health Globes, spending points into these skills isn't wasteful in anywayany way. It is unknown if the Strength boost from Invigorated will apply to Party members.
