You are able to quantum lock your position in space, giving you greater control over your movement and increasing your stability.
Prerequisites
Scorn earth class feature.
Benefit
Any time your movement speed would be reduced to 10 feet from using scorn earth (such as from wearing heavy armor or being more than 1 foot away from a stable surface), your speed is instead reduced by half, rounded down to the nearest 5-foot increment, to a minimum of 10 feet.
You do not take any penalty for attacking while affected by scorn earth, levitate, or psionic levitate at distances greater than 1 foot from a stable surface.
