Viper trinkets alternative ?
Yeah, sinister would be the next best stats.
Sinister yes, the easiest alternative after that would be rampager, but you end up losing a bunch of dps if you go for those.
Also assuming you’re going for fractals or whatever you need ascended preferably and getting ascended sinister ones is a pain, same goes for vipers. That is unless you’re prepared to farm a ton of Bloodstone Fen. Anyways raiding wise get exotic viper’s over anything else.
