searched the wiki and the search results came back with nothing. maybe overthinking this: is the Normal damage inflicted on both bts rolls (and apply bts effects + other CC skills such as shock)or just the first roll?
Each failed Saving Roll causes 1W and the E/M effects. Combined Ammo rules for reference https://infinitythewiki.com/Combined_Ammunition
Yes. See https://infinitythewiki.com/Combined_Ammunition and the example of DA+AP forcing two Saving Rolls which both apply the AP effect. In the same way, EM+N is two Saving Rolls applying all the effects of both ammunition types.
To expand on this clarification, If Nourkais lands two hits on his opponent in CC using the EM CCW, the opponent makes 4 N+EM rolls. And if he crits twice, he makes 6. Correct? All 6 saves could heal Nourishment through protheion as long as it doesn’t exceed his base wounds value by 2 correct?
Two rolls vs BTS divided by two ? Cause we slightly defer from the examples in the wiki. The example in the wiki shows two ammo rolling against the same attribute (ARM) Here we have N rolling against ARM and EM rolling against BTS (I think N+EM CC weapon are the only one doing that right now). I have trouble understanding why we should roll against BTS only.
Normal ammo doesn't have an assigned saving roll in N4. The weapon determines the saving roll, not the ammo type. For example, a Nanopulsar has Normal ammo vs BTS. A Breaker Pistol has AP ammo vs BTS.
