I use my Uzumi RR4 @310 light with a 5 round mag and triple tap. When triple tap procs I get to fire off 8 rounds before reload. I do more damage on bosses than those that use black spindle
Stillpiercer is way better than the raid one hands down. I have always been a fan of high impact snipers specially my #1 favorite Efrideets Spear. I dislike low impact snipers and imo they're trash...that's just me though so if anyone loves low impact snipers I respect that.
Anyways, speaking of snipers for the raid, you'll be fine with any high impact snipers. The raid sniper does less damage to bosses because of its low impact so you're better off with a yard stare, eirene rr4, spindle or stillpiercer.
I'm actually happy that the raid sniper can be useful in the game...yes to infuse my beasts high impact snipers.
They're both really great. I use still piercer on my hunter and Yasmin on my other two. I prefer the scope on still piercer though. I think that's what gives it a little edge for me. What matter the most to me though is whether I can one shot the boomer knights on top platforms at totems. If I can. It's a good sniper. I put a 310 hereafter into my still piercer because it couldnt do that.
I used to run the spindle but I like Yasmine better now. I know it's slow except being in an aura and I have to wait a few seconds to reload. I just prefer the way it fires over spindle.
