replacement
riven - primed bane of grineer, primed firestorm, galvanized scope or alternate critical delaywith vile acceleration

info for mods
serration- for initial damage you can replace this with racist mod since guncane is a thing
point strike-because this build is for spamming and [Critical Delay] wasn't a nice choice
vital sense-main source of damage is from crit
galvanized chamber-the multishot is multiplicative to everything calculated very important
primed cryo rounds-since we are equipping [Hunter Munitions] so we don't need to balance the slash and viral weight and since its general build so we will focus the initial damage, for higher level content its more wise to change to rime rounds (note:my bramma is initiate tox so that will be easy viral with these mod i mention)
hunter munitions-the only reason we use viral is this mod, viral amplifies damage to health(check wiki for more detail)
vigilante armaments-as i mention above about multishot this mod is somehow important it does +60% multishot and does boost set mod(tip: you can use this set mod equip with sentinel weapon even with active pet present)
vigilante supplies- SUPER SUPER IMPORTANT this mod allows you to convert ammo to bow ammo, i suggest using with fetch
riven mod is for boost some damage it does help alot but the mod i mention at the top are also good especially racist mod
