You are able to maintain your invisibility against opposing magic.

Prerequisite(s): Spellcraft 15 ranks, Stealth 15 ranks, 9th-level Arcane Trickster

Benefit: While you are invisible, if anything attempts to reveal you by using a spell or magical ability which specifically counteracts invisibility (such as invisibility purge or see invisibility), you may make a caster level check (DC 11 + the effect's caster level) in order to remain unaffected and undetected by the effect for one round per arcane trickster level. This feat does not counteract general antimagic effects such as dispel magic and detect magic.
