Level 1: 20-pt buy. All official races (up to and including 20 RP)/classes allowed (including unchained). May ask about 3rd party material. Two traits. 300 gp starting gold. Any alignment that can play well with others, follow orders, and perform morally gray missions. Alignment mechanics will matter so alignment may be shifted depending on actions.
Full hit die at first level followed by half hit die +1 at each subsequent levels. Con mods, favored class bonuses, toughness, etc of course add to the hp gained at each level.
Will use the alternative system designed to get rid of feat taxes.
Combat stamina feat is also available. Full BAB classes get it as a free bonus feat at level 1. I intend to bring martials relatively in line with casters in terms of flexibility and power at higher levels.
Submissions should include a character background right up until selection by the Shadows.
