Substats: Crit Mutiplier&ATK&Chill, last one can be weak point or darkness legion.
Core: Orange slots 2 ATK, Green slots 2 Fire Rate, free slot can be crit mutiplier, fire rate or chill for more specialized usage.
Core can grant u 160% ATK and u also have mental focus, rifling reinforcement can be replaced now. Overwhelm is for darkness legion only, if u want dagger for other enemies, u can switch it to weak point or ATK etc, depending on u.
Darkness and immortality legion can both be countered with chill attribute, cause actually immortality legion has even lower chill resistance than darkness.
This weapon in gley's hand is insane now, it can easily stack up to max crit chance, u won't need enzo, just gley herself. But if u want to deal with truth legion as well, then perhaps u need electric attribute. And since truth legion can be a little harder for head aiming, so maybe dagger isn't so effective. But for 30&27 stages, dagger is the most effective weapon now. And in 400% infiltration or colossus dagger can deal massive damage. Completely worth ur time and catalysts.
