Instinctive Obfuscation [reaction] Feat 13Gnome Illusion Visual Source Player Core pg. 53 2.0Frequency once per hour
Prerequisites at least one arcane or occult innate spell gained from a gnome heritage or gnome ancestry feat
Trigger You are attacked by a foe, but they haven’t rolled yet
The magic within you manifests as a natural reaction to threats. An illusory double of you appears in your space for a brief moment. The triggering attacker must roll a DC 10 flat check; on a success, the attack targets you normally; if they fail, the attack targets the double and destroys it. The tradition of this action matches the tradition of your gnome ancestry options.
