it is weapon for stealth attack + heavy attack , Happy Hunting

you have 1 empty slot for ur interest but in fact you really dont need it ,any combo mod will be useless otherwise [Ivara] get benefit of solid extra dmg+crit or crit dmg

everyday i farm in steel path hunting mission with this weapon and i kill acolyte " boss" with only 2 heavy attack hits

dont forget "chap chap" enemy with heavy attack
