While certainly not a Lex Prime, the Spira is still a formidable weapon in its own right. As it is silent and has a decent crit chance, this looks to be the sidearm of choice for stealth runs or characters with invisibility (namely, Loki and Ash). While you could elect to not use primed mods, you will loose out on a fair amount of DPS that way.
Built to proc status effects with high status chance and multi-hits. With the default damage being Electric (meaning no Slash/Puncture/Impact), status effects will only be elements.
Cold+Fire (Blast) and Toxin (Corrosive) [Grineer/Infested/Void]
> AoE knockdowns and melting Grineer armor, also great against Ancients
Cold+Toxin (Viral) and Fire (Radiation) [Grineer/Void]
> Significantly weaken enemies and keep them confused
Fire+Toxin (Gas) and Cold (Magnetic) [Corpus]
> AoE Toxin (ignores shields) and shield destroyer
Pretty balanced build for this incredible sentinel weapon with high status and critical chance, with also viral and radiation statuses which are really effective versus Grineer.
Those 3 formas are needed.
Standart utility build for general purposes. Good survival, melee and sniper mods.
Currently one of the costliest weapons to build. This requires 2 prime mods to achieve it’s maximum potential and a neat 6 forma since it came without polarities (hopefully DE fixes this).
Basically point and shoot and if you crit, they will feel this.
Don’t forget crit multiplier on head shots will make your damage skyrocket.
So no point fitting Vicious spread on this baby.
The increased mag size also makes punch through a little less necessary.
Although crit chances look low, but remember it is 47% chance to crit, PER pellet.
So each pellet has 47% chance to crit, so not too shabby.
If you want slightly faster reload speed and punch through.
Remove one of the elemental and squeeze in Seeking Fury,
My first build on the Telos Boltor. In this build I uses 3 forms, and no mistovich modules are hard to beat. In this build for 1 shot (cartridge) viditur figures in 20K. By the way this is the 1st build is about the Telos Boltor.
