I've been trying to work out the specifics for a new adept that would allow the adept to increase the concealment rating of the melee weapons he carried. The basic idea my friends and I have come up with is that for .25 power points per level, you gain 2 points of concealment you can add to a melee weapon you carry, or divide the points amongst multiple weapons. Example, Georugi is a melee centric adept, and he has 2 levels of weapon concealment. He can add 4 points of concealment to his katana, bringing it to a total of 7, or he can add 3 points of concealment to the katana and 1 to his wakizashi.
I would appreciate comments and opinions on how to keep this balanced and functional. I'm not intending it to be a [katana|hammer]space, but more of a 'masking' that makes it harder to perceive the weapon, so it would be easier to carry around a more substantial melee weapon than a knife without having to worry about getting harassed.
Costs, values, effects, nothing is set in stone, so any ideas are welcome.
