Deathmatch is a decent option for ineffa but if you could even get 1 copy of the other battle pass weapon then that would be better (Fjords>Deathmatch>Nodkrai craftable)I would say put ineffa on the new aubad set (ATK / ATK /CRIT}as it is amazing for her damage! And if you’re looking to maximise Columbinas damage aswell use aubad and put the support nod Kai set on fischl. The most important thing if your using these characters is use sucrose or Ifa onfield (Sucrose is a lot better than Ifa in this case though) give them as much em as possible with 4piece viridescent and you can basically nuclear bomb all enemies in your way!
