Awaken the Blood Help

For 20...39 seconds, you gain +2 Blood Magic and +2 Curses, but whenever you sacrifice Health, you sacrifice 50% more than the normal amount.

So if I use a spell that sacrifices 10% health. Does that mean it sacrifices 15% instead?

Sacrifice 10% health from 100hp.

Total Sacrifice 10hp.

With AoB Sacrifice 10% health.
With 50% more sacrifice of the 10%.
So total sacrifice is 15% from 100hp.

Total Sacrifice with AoB 15hp.

Got that right.

Thanks. I can amp my build up a few notches with this.

For some reason I always thought it would sacrafice 20HP from 100HP.. Reading and concentration FTW !

Fortunately I don't think that anymore.
