Willpower Mastery

So I just added another point to willpower. Should be healing at .6% of my health but I'm healing at .5%. I'm losing health at .6% from I forget what it's called but the poison mastery and it's clearly 10% higher than I'm healing. Is this a glitch?

Because as the previous posters have stated, poison inhibits healing by 30%. So instead of healing for .6%, you'll really heal for .6% x 70%
