The Alchemists - No Room for Error (passive skill)

[revengeance]

The description of the No Room for Error passive skill says that if you have less than 50% health, all your healing abilities will add 10% more heal but, I noticed that instead of 50% less health I think that it is 50% more health and not 50% less health because I get more heals if my hp is more than 50% and less heal if my hp is 50% less.
