Each 25-point grouping of Pattern breaks down into Shadowshifting (10) and Probability, P. Defense and P. Senses at 5 points each.

25 points: Simple shadowshifting. No hellriding, no walking to intangibles like time flow or a hot music scene.

Simple Probability manipulation, nothing too unlikely. You can alter the weather this way, slowly.

Pattern Defense, a sort of energy sink that grounds out hostile magical or other Power attacks, it takes your full concentration. Your combat abilities drop to Chaos, or Human if you start from Chaos level.

Pattern Senses: passively sense strong Pattern use in the area; with concentration, widen the area a lot or sense subtler uses.

50 points: Corwin-level shadowshifting. Hellride, shadows of desire, faster or slower shadows (not too fast or slow, a 5:1 difference is damned rare on the Amber side of the cosmos); send people or things through Shadow along known routes. You can create or destroy simple Shadow Paths (for transshadow commerce, etc.) with great effort.

More complicated Probability control.

Pattern Defense drops your combat abilities to Amber, or Chaos if you start at Amber.

Pattern Senses extend to use of other powers, range and or sensitivity increase.

55-100 Sectional costs (Sensing, Probability, etc.) double. Scary Fiona tricks. Individual tricks cost 5 points each. Gerard and Julian have definitely bought up expertise in making Shadow Paths, for instance.
