Custom Blood Magic: Ritual
Some chronicles allow for their players to develop customized powers for their characters. The following is a compilation of player created custom content in OWBN. At this time, custom content that is created and/or used by vampire PC's is required to be listed.

Comine your blood, and the blood of someone with the merit 'magic resistant'
Feed this blood to an ash or oak tree every night for a full cycle of the moon. (It only takes a trait per person involved, not a trait each night)
When a stick, stake, or club formed from this tree (only one can be made per casting) contacts someone (other then the caster) actively using blood magic (including rituals, and potency, ect), they stand to loose their blood magic for but a round.
The target can not use any blood magic for one full round, after which they may begin recasting. The stake/stick/club crumbles after one use. For each active power on the target, engage them in a contested willpower challenge to see if that power/ritual drops. Powers lost in this mannor can be recast the following round (but not this one). Rituals lost in this mannor must be recast as normal. (Requiring ritual casting times.)
