Hick Jr has made piles of sponsored magics. There's an Outsider one he made...I'll try to find it for you.
Here it is:
Sponsored Magic Master ListEdit: Turns out it was Vultur who did an Outsider version:
Outsider MagicDescription: Drawing upon the power of the Outside (or a powerful Outsider patron), you're able to cast spells that destroy, distort, ruin, or harm aspects of reality (time, space, energy or matter) and induce fear, despair, and horror.
Cost: 4 refresh, 3 if you have Evocation or Thaumaturgy, 2 if you have both. You also need to either be an Outsider, or have an Outsider patron.
Benefits: Standard sponsored magic benefits.
Evocation - Outsider magic may be used as an element for evocation; when used this way, it produces effects similar to the entropy aspect of water evocation, and can also produce veils (as per spirit evocation). Outsider evocation effects are always obviously and profoundly weird, warping and twisting aspects of reality.
Thaumaturgy - Outsider magic can produce the effects of entropomancy, as well as psychomancy and transportation/worldwalking effects appropriate to the themes of this magic (psychomancy cannot produce beneficial or calming effects, transportation creates teleport effects, etc). It also may produce limited chronomantic effects.
Evothaum - Outsider magic can produce Outsider-appropriate psychomancy effects with evocation's methods and speed.
Other Benefits - Outsider magic provides a +1 power bonus on evocations (not evothaum) which directly cause destruction or harm.
