A skill that sounds like it will be mandatory for most every Barbarian, unless equipment with health regeneration is common. The amount of regeneration was hard to read in our notes, but it is a low double digit number. Something like 10 or 12.Most likely one point will be enough for regenerating to full health while you are away from keyboard or in any way staying out of combat for a long time. Regeneration is usually not that handy in the middle of intense combat, since it works quite slowly, even at high levels.
