Sporefall Raid Guide — WoW Midnight Patch 12.0.7
Rotmire is the single boss of Sporefall, the one-encounter raid arriving with WoW Midnight Patch 12.0.7: Revelations. The raid sits in Harandar and is built as a short, focused weekly clear — closer to a 30-minute checkpoint than a full tier — but the encounter itself scales hard at higher difficulties and introduces the first proper test of Mythic Flex, a 15-to-25 player roster format the rest of the game has never used before.
Release Date & Difficulties
Sporefall is targeting the week of June 16, 2026 for live release, alongside the rest of Patch 12.0.7. Mythic Flex testing is scheduled on the PTR for May 14, 2026 at 1:00 PM PDT — the first time players outside Blizzard get to try a non-fixed Mythic roster size. The raid runs on the standard Midnight weekly lockout, with one kill per character per difficulty per week.

Notes |
| Raid Finder | 10–30 | 259 | Queue only, pug-friendly entry tier |
| Normal | 10–30 | 272 | Standard flex, premade or queue |
| Heroic | 10–30 | 285 | Ahead of the Curve: Rotmire available |
| Mythic Flex | 15–25 | 298 (Sporefused) | First Flex Mythic in WoW history; Cutting Edge here |
Mythic gear lands at item level 298, the same ceiling as weapons and trinkets fully upgraded with Ascendant Voidcores. One weekly kill of https://www.wowhead.com/ptr-2/npc=254176/rotmire on Mythic gives you the same per-slot ceiling as the entire https://www.wowhead.com/ptr-2/item=268552/ascendant-voidcore upgrade grind.
Location & Access
The raid entrance sits in https://www.wowhead.com/zone=15355/harandar, near the Grudge Pit, and only requires standard raid unlocks — no quest attunement, no progression gate. Minimum character level is 90, matching the rest of Midnight raid content. The introductory quest Sporefall: Rotmire hands you the bonus-roll item the first time you clear the boss on any difficulty.
The lore setup: a Spore Storm is building over Harandar, and Rotmire is the source. No prior questline, no group attunement — if you can open a raid lockout, you can start pulling.
Mythic Flex — First Time in WoW History
Mythic has been locked to exactly 20 players for over a decade. Sporefall is the first raid to break that rule, scaling boss health, damage, and add counts to any group size between 15 and 25. The point is to give guilds that consistently sit at 17 or 22 raiders a real Mythic option without forcing them to bench healthy raiders or scramble for trial recruits before every pull.
This is a Sporefall-only experiment, not a permanent change to the Mythic format. Hall of Fame and Race to World First standings do not apply here, because Sporefall is one boss with no leaderboard rank to defend. If you have been sitting on Ahead of the Curve and never quite got Cutting Edge because of attendance math, this is the raid built for that exact gap.
Rotmire — Fight Overview
https://www.wowhead.com/ptr-2/npc=254176/rotmire is a single-target encounter with constant add pressure, a fixed tank-swap rhythm, and a hard energy timer. The fight does not change shape over the pull — it keeps stacking pressure on the same loop, and the raid's job is to clear adds, swap on time, and keep boss damage moving so Rotting Pustules cannot run away with the healing.
Fight Style: Single-target boss with stacking raid-wide DoTs, repeating add waves, and mandatory tank swaps.
Recommended Setup (20-player baseline): 2 Tanks / 4 Healers / 14 DPS. Scale healers proportionally for 15-player and 25-player Mythic Flex.
Recommended Utility: Warlock Gateway between the boss and the off-tank kill zone, plus at least two reliable kicks for Sporecap casts.
Bloodlust: On the pull. Lust value falls off as Rotting Pustules ramps healer load, so the front-loaded burst is worth more than saving it for an execute window.
All Boss Abilities
https://www.wowhead.com/ptr-2/spell=1221637/fungal-bloom — The Wipe Condition
The 100-energy dump and the wipe condition of the fight. Rotmire releases a putrid miasma that hits every player for very heavy Nature damage and applies a 16-second damage-over-time effect, then knocks the raid back from his position. The same cast also fully heals every living add via Fungal Frenzy. If Shroomlings, Funglings, or Sporecaps are alive when the energy bar fills, they snap back to 100% health and the next cycle starts with extra add pressure on top of the rebuilding tank stacks. Your add cleanup window is the energy bar — not "soon," not "after a few more globals."
https://www.wowhead.com/ptr-2/spell=1221622/awaken-fungi — Add Spawner
Rotmire sprouts fungal growths around the arena that explode after a short delay, dealing minor Nature damage in 6 yards and knocking nearby players away. Each growth that resolves spawns an add — Shroomlings on every difficulty, with Funglings added on Mythic. The mechanic is light damage on its own, but it is the only source of adds in the encounter.
https://www.wowhead.com/ptr-2/spell=1221781/putrid-fist — Tank Swap
The only mandatory swap mechanic of the fight. Rotmire smashes his current target with a rotting fist, dealing massive Physical damage, knocking the player upward, and applying a stacking debuff that increases Physical damage taken by 75% for 16 seconds. Tanks must swap on every cast, no exceptions. A second Fist into the same tank lands on a 75% amp and is generally fatal even with externals layered on top. Defensive cooldowns belong on Fungal Bloom, not on the swap.
https://www.wowhead.com/ptr-2/spell=1222176/rotting-pustules — Soft Enrage
Rotmire periodically bursts pustules on his back, dealing minor Nature damage to the entire raid and applying a stack of Rotting Pustules — a stacking, persistent damage-over-time on every player. The stacks do not fall off during the encounter. Healer HPS requirement keeps climbing the longer the pull runs, which is the encounter's soft enrage timer. There is no mechanic to clear the debuff; the only solution is to kill the boss before your healers run out of mana.
https://www.wowhead.com/ptr-2/spell=1222088/festering-vines — Positional
Several players get rooted in thorny vines that deal Nature damage every second and slow movement by 30%. When the debuff expires, the vines snap apart and leave a Writhing Vines pool on the ground. Do not let the snap resolve while stacked on other players, and do not stand in the leftover pools afterward. Tanks should keep Rotmire away from the active add cleave zone so expiration pools do not pile up on top of the kill spot.
https://www.wowhead.com/ptr-2/npc=238699/sporecap — Heroic and Above
Sporecaps are environmental adds that spawn around the arena starting on Heroic. They cast Poison Burst — a stacking AoE damage-over-time on the whole raid — and shoot Blightshot at random players for sharp single-target hits. They are not optional cleanup. Letting Sporecaps free-cast stacks raid-wide pressure on top of Rotting Pustules and turns a manageable pull into a healing collapse. Treat them as priority targets the moment they appear.
https://www.wowhead.com/ptr-2/spell=1222684/cross-fertilization — Mythic Only
The headline Mythic mechanic. If a Shroomling corpse falls within 10 yards of a Fungling corpse, a Doom Shroom is created. Doom Shrooms detonate via Bursting Doom Shroom for very heavy Nature damage to the raid plus a long-duration follow-up damage tick. The raid has to kill Shroomlings and Funglings in deliberately separated kill zones — same arena, two corners — and never let the corpses meet. This is the mechanic that separates a clean Mythic kill from a chain of disaster pulls.
Role-by-Role Strategy
Tanks
Swap on every https://www.wowhead.com/ptr-2/spell=1221781/putrid-fist?dd=233&ddsize=25. The active tank takes the hit, the off-tank taunts immediately while the 75% Physical-taken debuff is still up, and the cycle continues. Position Rotmire away from the active add kill zone so https://www.wowhead.com/ptr-2/spell=1222088/festering-vines expiry pools do not stack on top of the cleave area. Keep the boss on a fixed wall side and let the off-tank handle the swap while the previously active tank rotates onto add pickup if Funglings are loose. Tank defensives go on https://www.wowhead.com/ptr-2/spell=1221637/fungal-bloom?dd=233&ddsize=25, not on the Fist.
Healers
https://www.wowhead.com/ptr-2/spell=1221637/fungal-bloom?dd=233&ddsize=25 is your wipe condition. Pre-cooldown every cast on progression, alternate healer cooldowns across cycles, and assume the raid will not survive a back-to-back Bloom without external mitigation. Rotting Pustules stacks make the second Bloom strictly harder than the first, and the third strictly harder than the second. Identify Festering Vines targets the moment the debuff applies, not when their health bar is already dropping. Save a major raid cooldown for Bloom 3 onward — by that point Pustules has stacked five or six times and recovery healing alone will not be enough to stabilize.
DPS
Track the energy bar and time personal cooldowns to catch adds in cleave. https://www.wowhead.com/ptr-2/npc=238696/shroomling , Funglings, and https://www.wowhead.com/ptr-2/npc=238699/sporecap need to die before the next Bloom. https://www.wowhead.com/ptr-2/npc=238699/sporecap need to die before they free-cast https://www.wowhead.com/ptr-2/spell=1221714/poison-burst more than once. Raw boss parsing while adds are alive is a measurable wipe contribution on this fight.
On Mythic, designate one corner of the room for each add type, kite them apart on spawn, and never let a corpse drift into the wrong pile. A single Cross Fertilization Doom Shroom can chain into a wipe through the next Bloom. Movement uptime matters — Festering Vines slows you 30%, Awaken Fungi knocks you off the boss, and the Bloom knockback resets positioning. Specs that handle movement cleanly — Demonology Warlock, Augmentation Evoker, Fire Mage with movement procs — gain a real edge here.
Loot — Sporefused Gear
Sporefall drops gear with the Sporefused tag — items that are pre-upgraded to a higher base item level than standard tier loot, with no upgrade currency required. Mythic Sporefused gear lands at ilvl 298, the same ceiling reached by weapons and trinkets fully upgraded through Ascendant Voidcore. From a single boss, once a week, with no upgrade investment required after the kill.
| Difficulty |
Sporefused ilvl |
Equivalent To |
| Raid Finder | 259 | Veteran-track gear |
| Normal | 272 | Champion-track ceiling |
| Heroic | 285 | Hero-track ceiling |
| Mythic Flex | 298 | Matches Ascendant Voidcore upgrades — above standard Mythic 6/6 |
Loot Table
https://www.wowhead.com/ptr-2/npc=254176/rotmire drops eleven gear pieces split across all four armor types, plus a neck, a ring, and a trinket. There are no weapons in the loot pool, which is consistent with Sporefall being a single-boss bonus raid rather than a full tier — weapon upgrades for Season 1 still come from March on Quel'Danas.
Weekly Quest — Free Nebulous Voidcore
Completing https://www.wowhead.com/ptr-2/quest=96746/sporefall-rotmire rewards a https://www.wowhead.com/ptr-2/item=269258/void-twisted-sporbit, an item you convert into one https://www.wowhead.com/currency=3418/nebulous-voidcore — the bonus-roll currency used by the Voidforge system across Midnight Season 1 content. The quest is granted automatically the first time you enter the raid, and credit is earned on any difficulty including Raid Finder.
Voidforge raid bonus rolls cost two https://www.wowhead.com/currency=3418/nebulous-voidcore per attempt, so the Sporefall quest gives you exactly half a raid roll per week. The most efficient approach: clear on the lowest difficulty to bank the core each week, then save stacked Voidcores for your priority raid boss target.
