Would these 2 abilities stack for 20 extra damage on moonbow procs for Athena (still a 4 Star but I’m not gonna wait to summon a 5 Star or wait for Karel because my luck is not nearly good enough for that to happen) or should I just hold on and wait until I get a unit who will benefit from wrath. I summoned 3 nephenees on the banner, one is built and one went to black knight for wrath, the last one is my final Wrath fodder
I don't have Wrath myself but I've seen this question answered as "yes" several times in the past. Wrath/Wo Dao+ is also listed as a build for Fir, Navarre, and some others on this site.
