Low gravity (0.1-0.5g): movement penalties, Reflex saves (DC 12) to avoid drifting, and Athletics checks (DC 15) to anchor.
Low gravity zones are areas with reduced gravitational pull -- a space Station, a moon, or a ship in zero-G. The zone is divided into tiers based on gravity: low (0.1-0.5g) and zero (0g). In low gravity, characters suffer a -2 penalty to movement and must make a Reflex save (DC 12) each round to avoid drifting; failing the save imposes the Prone condition. In zero-G, characters must make a Reflex save (DC 15) each round to avoid drifting and an Athletics check (DC 20) to move. Magnetic boots and grapple guns grant +4 resistance to these checks.
