Ad Astra Per Arcana
You are trained to fight in conditions of varying or zero gravity. This could be when you fall overboard or when your ship’s gravity plane shifts.
Prerequisite: Dex 10+, Int 10+, Spacefarer.
Benefit: You suffer no penalty to actions in low or zero gravity, and you receive a +4 bonus to keep your balance when the gravity suddenly shifts. In addition, your character will not provoke an attack of opportunity when performing an action, unless that action would normally provoke one.
Normal: Without this feat, most actions suffer a -4 penalty in zero gravity, and actions in a low-gravity environment suffer a -2 penalty. The character does not threaten the area around and cannot perform attacks of opportunity, while any action he takes provokes one.
