Molten Core 25 is the classic 13-boss raid from World of Warcraft 1.0 and the second-easiest 25-man in WotLK 3.3.5a. The raid is where new guilds cut their teeth — the mechanics are simple, the loot is Tier 1-2 (100 iLevel, useful for twinks and gold-making), and a first-time group can clear it in 2-3 hours. Most veteran guilds clear it in 30-45 minutes as a "cheap lockout" raid.
This guide is for WoW Forever players in 2026 who are stepping into Molten Core 25 for the first time. By the end, you'll know all 13 boss mechanics, the Shazzrah's Hat quest, and the fastest clear path.
Quick answer up front: Molten Core 25 is the second-easiest 25-man in WotLK 3.3.5a. The raid needs 150+ iLevel average (twink-friendly), 20-25 players, and 2-3 hours. The 13 bosses are Ragnaros, Magmadar, Golemagg, Shazzrah, Baron Geddon, Sulfuron, Majordomo, Ghnore, Razorgore, Vulfire, Onyxia, Shamanrah, and Core Hounds. The loot rewards Tier 1-2 tokens (100 iLevel).
Raid requirements for Molten Core 25
Minimum gear
- Average iLevel: 150+ (fresh 70 boon, or any 80 character).
- Tanks: 60,000+ effective HP.
- Healers: 300+ HPS.
- DPS: 500+ DPS.
The raid is twink-friendly. Because it's classic-era content, a level 70 with dungeon gear can clear it. Most guilds use it for twink gearing and gold-making (the trash mobs drop a lot of gold).
Minimum composition
- 2 Tanks: 1 Main Tank, 1 Off Tank.
- 18 DPS: Any mix of melee + ranged.
- 5 Healers: 3 Holy Paladins, 1 Resto Shaman, 1 Priest.
Healer note: The boss mechanics are very light on healing, so 3 healers is enough. The trash mobs do more damage than the bosses.
The Molten Core boss order
Molten Core has 13 bosses, but they're not linear. The path is:
- Lair of the molten defenders: Shazzrah, Baron Geddon, Sulfuron, Golemagg the Incarnate, Shamanrah.
- The Molten Giant: Majordomo Executus, Ghnore, Razorgore the Untamed, Vulfire Golem.
- The Emberwing: Onyxia, Domination of Magmadar.
- The Fire Lord: Ragnaros.

Boss 4: Golemagg the Incarnate (the wall)
Golemagg is the first boss in Molten Core that requires a coordinated strategy.
The mechanics
- Golemagg the Incarnate: 1.2 million HP, 9x normal. Must be killed first.
- Core Hounds: 2 adds with 60,000 HP each. Spawn when Golemagg dies.

The strategy
- Kill Golemagg first (tank it, burn it down).

- Kill Golemagg the Incarnate after the adds.
The wipe point: If the Core Hounds aren't killed, Golemagg heals for 20% per hound alive.

The strategy
- Tanks: Kill the adds.
- Healers: Interrupt the Healing Wave.
Expected kill time: 1-2 minutes.
Boss 6: Majordomo Executus (the mid-raid wall)
The mechanics
- Adds: Summons 4 Elite Blazing Elementals, 6 Invoker Inferno adds, 4 Flamewaker Adds, 8 Rockfire Summons. Must be all killed.
- Summon Entities: Majordomo summons adds at 100%, 50%, and 20% HP.

The mechanics
- Razorgore (channeling): Razorgore channels a spawn for 10 seconds. If the channel completes, he spawns 4 whelps. If not, he dies.
- Adds: Summons 8 Razorgore's Add whelps during the channel.
- Spawn of Dragonkin: Summons 4 whelps every 30 seconds.
The strategy
- Kill Razorgore's Adds (the 8 whelps at the start).
- Razorgore channels → the raid must damage him to 10% during the channel to kill him.
- If the channel completes, kill the 4 whelps and reset the channel.
The wipe point: If the raid doesn't damage Razorgore during the channel, he spawns whelps. If they survive, they heal him.

The strategy
- Healers: Dispel the Magma Shield.
- DPS: Kill the Lava Spawns.

Boss 9: Onyxia (the flying boss)
The mechanics
- Onyxia is the air phase + ground phase boss (see our WoW Forever Onyxia 25 Raid Guide (2026) for the full mechanics).
In Molten Core, Onyxia is a simpler version (no Whirlpool, no 280% flying requirement). She flies at 66% HP and 33% HP.
The strategy: Same as Onyxia 25 but easier. The Deep Breath is shorter (covers less of the map).
Expected kill time: 3-5 minutes.
Boss 10: Ragnaros (the final boss)
Ragnaros is the final boss of Molten Core and has 2 phases.
Phase 1 (100% to 10% HP)
- Lava Pools: 8 puddles spawn under players. Move out.
- Fireball: Casts a 3-second AoE. Use cooldowns.
- Melee Quake: Casts a knockback. Prepare for it.
- Wrath of Ragnaros: Raid-wide fire damage on 50% and 30% HP.
Phase 2 (10% to 0% HP) — the classic "Son of Ragnaros" phase
At 10% HP, Ragnaros sinks into the lava and spawns 4 Son of Ragnaros adds (elite elementals) plus 12 Magma Spawn adds.
- Kill the 4 Sons (they heal Ragnaros).
- Kill the 12 Spawns (they heal Ragnaros if alive).
- Ragnaros is immune to damage until all adds are dead.
The wipe point
If any Son or Spawn is alive when Ragnaros is pulled, he heals 10% per add. You must kill all 16 adds before resuming damage.
Expected kill time: 4-6 minutes.
The Shazzrah's Hat quest
Shazzrah's Hat is a MoP-era addition to Molten Core:
- Head slot: BoE helm with +1% damage to all attacks.
- Drop rate: 100% (it's a quest reward, not a random drop).
- Quest: Kill Shazzrah and turn in to the NPC at the Emberwyrm.
Shazzrah's Hat is the must-have for any twinking character in WotLK 3.3.5a.

The fastest Molten Core clear path (2026)
The fastest clear is:
- Kill all trash in a single pull (the trash is more dangerous than the bosses).
- Kill each boss in order (no skipping).
- Loot the bosses on the way.
Total clear time: 30-45 minutes for a veteran guild, 2-3 hours for a first-time group.
The gold value: A full Molten Core clear (including trash) drops 5,000-10,000g — one of the highest gold-per-hour activities in the game for low-level characters. See our WoW Forever Gold Guide: How to Earn 1000G in Your First Week (2026) for the broader gold path.
