Fire Primal Strike Elementalist
Blazerush allows us to convert lightning damage to fire damage fully if we play as a Demolitionist. And we can thus convert Shaman’s Primal Strike. It is rather a meme build but a good one. Physical damage on Primal Strike is also converted with this weapon. Both classes have access to health regeneration and so the defense will lean into this and items as well. Ideally you want two Gollus’ rings. Additional healing is from ADCtH and Wendigo Totem. Haunted steel is also important for healing when things get tough. It unfortunately converts some physical damage to vitality but DPS loss is negligable compared to the healing. There is damage absorption from Primal Bond and Blast Shield. Chest armor provides aura with % damage reduction. Giant is bound to Blast Shield for healing when it is actually needed. There are four circuit breakers from Serenity, Ghoul, Prismatic Diamond and Blast Shield. Build also uses Meteor Shower from devotions. You also have Wind Devils and Cinderwind proc from the gloves. Thus there is a lot of mayhem on the screen and unfortunately you often don’t see the enemies much due to this. Other items are chosen to complement the build for their additional bonuses. Build has lower % fire damage but it is compensated by access to resistance reduction from both masteries and total RR can be up to -139 %. This build can clear SR 34-35 fine and also SR 36-37 consistently.

This build is just a template. Customize it to your own liking. Instead of Gollus’ rings you can also use Mythical Combustion Band and Mythical Eternal Band. Other option for medal is craftable Mythical Volcanum. But the build will be weaker with these choices. Arcane Spark is necessary for energy sustain.

SR
I finished SR 34-35 5 out of 5 times within the timer. Some enemies can be dangerous. Benny’s hits are dangerous. During Valdaran’s aura use Bloodthirster. Use Bloodthirstier proactively in appropriate moments. Due to a large AoE you sometimes agro more bosses in boss rooms than just one. Due to many effects it is hard to see bosses.
In SR 36-37 I finished 3 out of 5 times within the timer. Damage output is good but build is squishier. You can get away with one death usually and still finish within the timer. You can always finish it. Benny can oneshot you so avoid his hit. Physical hitters are dangerous. Grava is not a big problem and neither is Iron Maiden.
Celestials
Ravager of Minds can be killed without pharma. Avoid his null and sunder.
Callagadra can be killed without pharma. It is slower but fine if you avoid tornadoes and sunder.
