Allergic

Allergic is a status ailment only in Paper Mario: The Thousand-Year Door. It negates all other status effects for two turns, meaning that Mario or his partner are invunerable to any status effects bestowed upon them. However, this also means that they cannot use status-raising items or the Star Power Power Lift. It is indicated by a small universal "No" symbol above the afflicted. Mario or a partner can attain this status through eating Space Food.
