Masters Rite

As a veteran member of the Blood Hunters you learn an advanced but dangerous form of crimson Rite. 

The Masters Rite is an alternate way of using any of the Rites you already know. This doubles all Rite damage while it is active.

When you activate the Master Rite, you lose a number of hit points equal to one roll of your hemocraft die at disadvantage, from then on to keep the Rite active a normal hemocraft roll must be made at the start of your turn (if you have less hitpoints remaining than your hemocraft dice maximum the rite ends)
