I promise this question isn't about crits with an em ccw. So a domaru with his duel wield hits a dude in cc. The guy getting hit has to make an armor roll and a BTS roll. Reason being because em goes against bts while the ccw part goes against armor. If I'm right so far does only the armor roll cause a wound and only the bts roll cause isolation and potentially imm2 if able? Or is it that both rolls can cause a wound/isolate? Is the interaction similar to that of the breaker rifle+marksman zhaeyadan? With him each or his successful uncancelled hits cause two checks each 1 for armor and 1 for bts because of the breaker ammo type hitting bts and shock from marksman hitting armor. Obviously each of those checks would cause a wound.
E/M CCW cause both a normal hit (vs. ARM) and an E/M hit (vs. BTS) naturally: E/M Special Ammunition and CC Weapons Close Combat Weapons that use E/M Special Ammunition cause Normal damage in addition to the E/M effect. Critical hits in CC are always applied to the E/M effect. Consequently, the target must make an ARM Roll in addition to the BTS Roll (with half its usual BTS value). For both Rolls, the CC Weapon's Damage is the trooper's PH Attribute. http://infinitythewiki.com/en/Electromagnetic_(E/M)_Special_Ammunition Failing the ARM roll results in losing 1 point from W/S. Failing the BTS roll results in being Isolated/Immobilised. (since it's a Domaru who is probably dual wielding using a Shock CCW as well, failing the ARM roll will kill a 1W trooper due to the shock effect)
