Absorption will give you 2 hearts that will regenerate every thirty seconds. At least that was the idea.

The real truth is that it doesn't regenerate at all. just like the health boost was regenerating in 1.6.1, the absorption isn't regenerating in 1.6.2.

This is something anoying, as of I'm building a PvP-arena I'm using absorption and it's quite anoying when a compilation error like this actually went through to release, when it actually worked before. Health boost and absorption is obviously extending the same class or something like that.
