You can summon SupernaturalCreatures to your aid. This must be a specific type of creature, as specified when the power is bought. Additional types can be bought for additional schticks.
The difficulty is their Powers skill, and each attempt costs a Magic point (if you use some unusual component, such as corpses to animate or a sacrifice to a demon, the call is free).
You get either one named creature or a number of unnamed creatures equal to your Outcome (minimum one).
You are usually on friendly terms with whatever creature you call. Unnamed creatures adore and follow you, while named creatures may have a more cynical approach to being called to help you in some foolhardy fight. Creatures usually walk off between adventures or even between fights.
