Assassin/Ninja Help Need A Thundra/ivory Build

ya pretty much what the title says, preferably using Boreal-infused since i already have that

thanks

 

does that mean you want a thrunda ripsaw build with an ivory secondary? or separate builds for both weapons?
anyway heres a hybrid that can use both the 6mr shouldnt be a problem since theres also 3ms. needs a good prism but is quite lenient on the far cosmos. damage kinda low
heres a ripsaw only build focusing on damage
for an ivory build i guess use the first one or maybe this it actually uses the bpa u wanted
