I have some ideas, but want to make sure I’m understanding the Arcana.

Mind ••

Mind shielding seems like an obvious answer

Life ••, Death •

I feel like this would break a blood bond in oneself. Life lets you heal damage from other supernaturals, I imagine having a dot in Death makes it easier to target undead effects.

Prime ••••

This I’m the least sure about. In fact, I’m pretty sure it would not help. Prime lets you sense other supernatural creatures, observe their Pattern, and even harm ghosts and spirits. It also lets you counter magic very well. However, I understand magic is magic, and vampiric powers do not interact with mana. If I’m really reaching, a mage might be able to purge their own Pattern of the taint a blood bond.
