Resilience
From NsdWiki
Typically used with: Self-Control.
In short: body control. Resilience is a measure of a character's inner fortitude, the ability to shrug off magic which distort a target's body. Any supernatural phenomenon which distorts a character's physical being is opposed by a Resilience check: shape shifting, petrification, disintegration, or psychokinetic clothing removal.
Resisting Spells
Many mutative spells and transportive spells can be avoided with a Resilience check, for instance Banish and Petrify. In this case, you may add any points in Magic Defense to this roll. The mage makes a Casting Roll. You make a Resilience check. If your result meets or exceeds the Casting Roll, you elude the effects of the spell.
