I really wanted to make a build around the new Legacy of Rose staff that was added in 3.26. This staff summons the shaper after spending 2000 ES to either do a slam attack, shoot the ball projectiles, or shoot the shaper beam. This build uses the slam (Shaper Devistation) to support purifying flame with large shocks. I leveraged a few key aspects of the item to form the cornerstone of the build.

• It has a large Phys damage mod for a caster weapon so Battlemage would give ~450 flat phys to spells

• Inquisitor can also sustain my high mana costs with Pious Path feeding my life regen to my ES regen

• Coiling Whispers soul eater tech both ramps up the cast speed to summon the shaper more and allows the use of Fanatacism via 225% attack speed + leap slam

• +5 all spell skill gems is a large DPS increase that makes the staff viable as well as boosting auras and support skills.

Purifying Flame was chosen as my primary skill since it generates a large amount of consecrated ground and the base damage is physical. It also converts half its damage to fire which is good for trinity but bad for doryani prototype tech.

Playstyle is to leap slam enough to sustain fanaticism and stay close to rares to keep soul eater stacks up. Mind over matter helps with max hit and you have so much regen you wont even notice it.

The shaper aspect of the staff sadly fails in dealing damage significantly but what it does do is hit really hard once, which is great for applying large shocks. I convert all his damage to lightning and give him overcharge and use it for bosses or just whenever because its fun. He takes a while to attack so it usually misses on trash since its already dead.

The Coiling whispers duration tech is very tight and you must pick up all of the reduced skill duration nodes as well as link temp chains with a 21/20 or 20/23 less duration support. All the other gems should be 1/0. Sadly the staff hurts us here because it forces temp chains to be level 6, though the reductions above are enough for it to work.

You need the forbidden flesh/flame for fanaticism, but these are currently pretty cheap at 20-30c or so. Other super important items to get right are the Lethal pride gem and the Watchers Eye with 25% phys as lightning. Both of these items can roll an absolute ton of great and useful mods for you, the lethal pride in particular hits 8 different notables that you were planning to take anyways with potentially up to 11! They are also 1 div or less so don't skip them thinking it will be too expensive.

Get a fallen Reverend merc with zealotry and wrath if you can. He can be built out with a doryani prototype (even if half our damage is fire) or you can go for Garb of the Ephemeral for tank. Victario's Charity (or the replica) can give Frenzy or Endurance charges but has lightning res so it doesnt work with Doryani. Otherwise Zealotry/Wrath aura effect scepters are good damage with Perquils toe/shaper seed.

If you use Trinity support, keep an eye on your fire/lightning damage to make sure it stays even, there's a lot of Phys as extra and -resists in this build that can throw off the balance.

Doppelgangers guise helps a lot with oneshots and phys damage as well as giving a lot of regen. Spend money on a +2 duration or +2 AoE corruption implicit if you have money and its a nice damage boost. Awakened Added Fire Damage and Awakened Elemental focus also give +1 to gem levels, though you lose shocks with the 2nd one (the damage is probably worth it).

Runegraft of the Jeweller with a completely unlinked staff also gives 60% increased damage, to unlink all sockets you must benchcraft 2 sockets, unlink them with a fusing then in sequence craft 3 sockets, 4 sockets, 5 sockets and then 6. Otherwise you will never hit it with fusing orbs. Finally, Runegraft of the warp was supposed to increase fanaticism duration by 30% but it doesn't work despite fanaticism being a buff. I kept it since its nice to have anyways but its not terribly important.
