Came up in a teaching game of N4. Hulang with mono-CC weapon fights a Muyib with Bioimmunity. Does the BioImmunity work vs monofilaments setting the arm to 0?
My understanding is that it does still set the ARM to 0 but they can choose to take it on their BTS instead, which is unaffected.
Bioimmunity can choose to use ARM 0 (fixed bu Mono) or full BTS value. Anyway, if the saving roll is failed, goes straight to dead
