Mythic Sporefall Lockout & Bonus Rolls Guide

The Mythic Sporefall lockout does not behave like every other Mythic raid in the game's history. Instead of locking you to the instance ID after a kill, it works like a Heroic lockout: you're barred from direct drops, but you can re-enter, re-kill, and help other groups all week on the same character. No alt-swapping required.

Whether this is intentional or a side effect of Mythic Flex raiding: the experiment letting groups of 15 to 25 players enter Mythic instead of a fixed 20: is not confirmed. Blizzard hasn't said a word. Enjoy it while it lasts, or until a hotfix quietly kills it.

Status: Not officially confirmed as intended. Treat it as live until it isn't.

Bonus Rolls: The Part That Actually Matters

Here is where it gets interesting. The Voidforge bonus roll window opens every time you kill Rotmire on Mythic: even after your direct loot is locked. Kills two, three, and four this week will all prompt the roll screen. If you have Nebulous Voidcores sitting around unused, Mythic Sporefall is exactly where you should spend them.

At 298 item level, Sporefused loot is the highest-ilvl gear in Midnight Season 1. No upgrade currency, no Ascendant Voidcore grind. One kill, max ilvl: the same ceiling it takes weeks of upgrade farming to reach through any other route.

Voidforge raid bonus rolls cost 2 Nebulous Voidcores per attempt. Stack your cores before burning them on re-kills.

Bonus roll flow

1. Kill Rotmire on Mythic (first kill this week: collect direct loot normally).
2. Re-enter with a new group. Kill again. Bonus Roll window appears.
3. Spend 2 Nebulous Voidcores per attempt via the Voidforge system.
4. Roll for Sporefused 298 gear. Repeat until your Voidcores are gone or your soul is.

The quest reward is one Void-Twisted Sporbit per week, converting to one Nebulous Voidcore. That covers half a raid bonus roll. Pair it with a second core from the Great Vault or M+ and you have one full Voidforge attempt on Sporefused loot. Thrilling math.

Mythic Flex: Why the Lockout Works This Way

Sporefall is the first raid in WoW history to run Mythic Flex scaling. Groups between 15 and 25 players enter Mythic, with boss health, damage, and add counts adjusting dynamically. This is a PTR experiment: not a permanent format change: but it is almost certainly why the Mythic raid lockout behaves like a flexible difficulty rather than a traditional instance lock.

The practical upside: guilds that perpetually sit at 17 or 22 players and cannot hit exactly 20 finally have a Mythic option. Rotmire Mythic does not require bench decisions or emergency recruitment. You bring who shows up, within the 15–25 bracket, and the boss scales to match.

15-player Mythic: boss health is lower, but every mechanic targets a higher proportion of your raid. You will be the soaking target more often. This is not easier: it is differently punishing.

Recommended Mythic setup (20-player baseline)

• 2 Tanks / 4 Healers / 14 DPS
• Scale healers proportionally for 15 or 25 players
• Warlock Gateway between boss and off-tank kiting zone
• Minimum 2 reliable interrupts for Sporecap casts
• Bloodlust on pull: Rotting Pustules stack all fight, so front-load burst

Rotmire drops Sporefused gear across 11 armor slots covering all four armor types, plus a neck, a ring, and a trinket. No weapons. Weapon upgrades for Season 1 still come from March on Quel'Danas, the Voidforge, and Mythic+. If you came here for an axe, leave.

Notable drops

• Sporelord's Mycelial Insignia: the trinket. Most contested slot in the pool.
• Rotmire's Sporeheart: neck piece.
• Sporecaller's Blooming Loop: ring.
• Cosmetics: Luminous Rotshroom (housing decor), Mycomancer's Hearthspore effect, Madcap Redcap toy: available on any difficulty.

The Luminous Sporeglider mount comes from a weekly quest: kill Rotmire on any difficulty, collect a Delicious Sporesnack. Four weeks of this. LFR counts. Difficulty is irrelevant. Do not run Mythic for the mount.

Rotmire: Don't Let the Mushroom Outlast You

The fight is an energy timer with stacking raid damage. Rotmire fills to 100 energy and casts Fungal Bloom: heavy Nature damage, 16-second DoT on the entire raid, and any adds alive at the time get fully healed and empowered via Fungal Frenzy. That is your wipe condition. Not DPS. Not healing. Add cleanup before every Bloom.

Meanwhile, Rotting Pustules stacks on the entire raid all fight and does not fall off. Your HPS requirement climbs continuously. The longer the pull runs, the worse it gets. Kill the boss before your healers run out of mana. That is the entire mechanic.

Tank rules

• Swap on every Putrid Fist. Non-negotiable. The active tank takes the hit, off-tank taunts immediately.
• A second Fist into the same tank with the 75% Physical-taken debuff active is fatal. Every time. Save defensives for Fungal Bloom, not the swap.
• Keep Rotmire away from add kiting zones: Festering Vines pools layer and become unmanageable.

DPS rules

• Shroomlings and Funglings must die in separate areas. If their corpses land within 10 yards of each other, a Doom Shroom spawns. This mechanic ends guilds.
• Kill Sporecaps immediately. They cast Poison Burst and shoot random targets. They are not optional.
• Damage cooldowns align with add windows: the cleave has to finish adds before Bloom.

Burst AoE priority: Classes with strong cleave and reliable defensives perform best here. The fight rewards add-control, not single-target throughput.

Weekly Sporefall Checklist

In order of efficiency. Don't overthink it.

1. Clear on any difficulty to complete the Sporefall: Rotmire quest: claim your Void-Twisted Sporbit. LFR is fine.
2. Kill Rotmire on Mythic for direct Sporefused 298 loot.
3. Re-enter Mythic with a new group and bonus roll via the Voidforge (2 Nebulous Voidcores per attempt).
4. Repeat step 3 until cores are depleted or boss is on farm. You can kill Rotmire as many times as groups will have you.
5. Kill on any difficulty once a week for the Delicious Sporesnack (mount progress, 4 weeks total).
