I've made Advanced Pattern mirror the novels -- Fiona and JoJ tricks.
Shift shadow in Amber.
Nullify, glitch or aid other people's use of powers.
Shift shadow without moving.
Scry across many shadows for Pattern or Logrus traces.
Hide or make obvious traces of most powers.
Shortcuts through shadow.
Blessings and curses. (Not to be confused with far more powerful death curses.)
Used a simple skills system. Anything that fits background at a professional level. World class skills for 1-2 points. So, no, Warfare doesn't make you a super-thief, -driver, etc.
Used Madeline Ferwerda's take on Shapeshifting.
http://www.z-amber.com/soad/soadrules.htmlCut the point cost of Trump Artistry to 25 and got rid of 'Trump powered items'.
Defined Control of Contents as effectively making the owner #1 in Psyche and any powers they have while in their shadow.
C o Destiny allowed the owner to banish anyone from his world -- the next step the banished one took exited the shadow, the banishee couldn't find it again, any location Trumps of the world the banishee tried to use were destroyed upon contact and anyone attempting to pull them through to it got expelled.
Pattern death curses didn't lay down Bad Stuff. They laid a new, narrow, fundamental law on the multiverse. Benedict got cursed by Dara with, "Never heal." Shortly thereafter Ben cursed the leaders of Chaos with, "Success." Meaning their enemies', against them. The only way to get rid of one would be for another Pattern initiate to die laying down a contrary blessing.
