native flats are all their own source
doesn’t matter where the WD is, proc, skill, devo, auto attack, you get 1 source, highest amount counts,
just like the baked in trauma on RF doesn’t get turned into multiple different sources via wps, it’s still the same source, just different attack application/“application doesn’t matter source does”
(smite/smash = 1 rf native dot, 1 wd dot, but you get an additional dot on smash since smash has native too so now you have 3 combined dots in “1” attack applied)
