Special 3 sometimes not doing damage
I have no idea why this is happening but I have been rerunning the Legendary Side Quest over and over because I keep losing champs and sometimes using the same champ on the same enemy I deal damage with SP3 and sometimes I don't. It is the top left path with the reduced damage node EXCEPT for specials and heavies and something else. There is nothing in that node that I can see that would make a SP3 do no damage.
Some of the fights are Doom against the Venom, Vision classic against Thor Rag and Immortal Abomination against Mangog.
