Bioimmunity allows me to pick ARM for my Yan Huo instead of BTS that E/M wants when hit by E/M. E/M asks to halve BTS, does picking ARM mean I save on full 5 ARM because E/M specifies only BTS to be halved?
It states that you may choose what attribute you use regardless of attribute the weapon indicates . Based on that I'd say you halve the ARM as you have now changed the specified BTS attribute to ARM attribute. EDIT: Fixed some typos
I think it's probably an oversight on their part to not account for the potential of Bioimmunity to impact E/M ammo. But given the way AP is written to clearly accomodate modifying either value, the way the rules are currently presented definitely strongly suggest E/M only halves your BTS. There's a certain logic to it but I don't think it's intended.
It's kinda elegant in the way it doesn't turn ARM into wasted points if you have a high BTS and bio-immunity
Probably because AP is written with acting as multiple N3 ammo types needing to be both AP and Breaker ammo. E/M on the other hand was written as a standalone.
