Allergenic

undefined: Allergenic is a system/headmate origin that is created by or related to allergies. An allergenic system or headmate could form due to an allergic reaction, stress caused by allergies, ect.

An allergenic headmate will commonly be an allergy symptom holder (more/less sensitivity to the allergy that formed them), an allergy protector (protects the body from their allergies), or an allergy persecutor (sabotages the body with its allergies).
