 - ```ETHEREAL```  You will not drop your items if you gain the `incorporeal` effect.
 - ```ELECTRIC_IMMUNE``` You are immune to electric damage.
+- ```EMP_ENERGYDRAIN_IMMUNE``` Your bionic power cannot be drained during an EMP blast.
 - ```EMP_IMMUNE``` You bionic power cannot be drained and your vulnerable electronics cannot be broken during an EMP blast.
 - ```ENHANCED_VISION``` Increases the scouting range, similarly to `ZOOM` item flag.
 - ```EYE_MEMBRANE``` Lets you see underwater.
