Mage Knight: Machination
Prerequisites: Magus level 4th, must have spent at least a year absorbing blackstone radiation
Benefits: Your magic is more resistant to antimagic effects. When within an antimagic field, you may make an opposed caster level check (1d20 + caster level) against the antimagic field’s caster’s caster level in order to cast a spell. You must make this check each time you attempt to cast a spell.
Likewise, if you have cast magical effects on yourself, you may make a similar check upon entering the antimagic field, once for each effect, to attempt to keep the effects active for the entire duration you occupy the field (or until the effects end). Failing the check suppresses the effects until you leave the field.
