The Order of Secrets
Support is a secret skill that allows it’s user to aid others in combat. It’s related to World Hacking in nature. Most often this is used with Special Moves. You can do things like healing a group of people (as an Ultimate), or add a bonus when trying to go through a door, or with unlocks to make attacks using various tools.
It has no real use in the ‘mundane’ world, since most would take it to be ‘magic’. However it can be used kind of a like a universal craft skill. This is always at one rank lower than the skill itself though.
