The reason behind this build is to make The Mageslayer set work with cold Devastation. Build uses Olexra’s Flash Freeze to freeze enemies and then you drop Devastation on them and Trozan’s Sky Shards. For cold devastation Arcanum Frigus gun is needed. For shorter cooldowns the build uses huge cooldown reduction and Eternity relic. For spamming between spells and for healing with lifesteal Chain Lightning from component is used. Your main defense is freezing enemies, then lifesteal, Pneumatic Burst, Ghoul and Mirror. Build is a glass canon. In long battles you will have to take energy potions. SR 65-66 is relatively easy.
I have other builds using OFF here.
Here is a list comparing all my Olexra builds from best to worst. All are at least SR 65-66 capable.
Olexrian Luminari – great build, OFF + DW ranged elemental Beronath‘s Fury, offensively a little slower, defensively quite tanky (best of my OFF builds)
Olexrian Judge – great build, OFF + physical Obliteration and Judgment, offensively a little better than Olexrian Luminari, defensively weaker than than Olexrian Luminari
Olexra of Kalastor – great build, OFF + fire RoK and FoI, offensively a lot better than Olexrian Judge, defensively a little weaker than Olexrian Judge
Spinning Freezer – great build, OFF + fire EoR, offensively a little better than Olexra of Kalastor, defensively a little weaker than Olexra of Kalastor
Olexra of Vire – great build, OFF + fire Vire and Judgment, offensively a little better than Spinning Freezer (best of my OFF builds), defensively a little weaker than Spinning Freezer
Olexra of the Sky – great build, OFF + cold TSS and Devastation, offensively a little weaker than Olexra of Vire, defensively similar to Spinning Freezer
Albrecht von Frozenstein – good build, OFF + fire AAR, offensively a little weaker than Olexra of the Sky, defensively a little weaker than Olexra of the Sky (but better than Olexra of Vire)
Albrecht the Freezer – good build, OFF + fire AAR, offensively and defensively similar to Albrecht von Frozenstein
Olexra of Menhir – OK build, OFF + fire Aegis and Vire, offensively a little weaker than Olexrian Luminari (weakest of my OFF builds), defensively a little behind Albrecht the Freezer
Build uses two green monster infrequent items - Terrnox’s Aether Tome and Stoneplate Greaves. Affixes are chosen for resistances. Two crafting bonuses are to freeze resistance and stun resistance.

I play SR with camera pointed away from enemies and I try my builds only in SR 65-66 and SR 80. I play around 10 SR runs per character.
This build does SR 65-66 easily. It can even do SR 80 with good mutators (if you can freeze enemies) but it is tougher. It is squishy in SR 80. If you can’t freeze Kuba and Reaper it would be impossible in SR 80. Cold resistant nemesis are slower to kill.
I don’t play Crucible so I don’t have a time number for it.
