“WoW Forever Naxxramas 25-Man Raid Guide (2026)”

✦ Editorial

Naxxramas is the first 25-man raid of WotLK 3.3.5a and the most-played pre-ICC content on WoW Forever in 2026. The 15-boss progression from Anub'Rekhan to Kel'Thuzad is the standard raid ladder for new 80s, and clearing Naxxramas 25 is the threshold for "ready for ICC 25 normal."

This guide is for WoW Forever players in 2026 who are stepping into Naxxramas 25 for the first time. By the end, you'll know the boss order, the basic mechanics, the loot priority, and the path to The Immortal achievement.

Quick answer up front: Naxxramas 25 on WoW Forever 2026 takes 2-3 hours per full clear for a competent guild, and you need a minimum of 18-22 geared 80s to start. The first 8 bosses (Spider + Plague wings) are clean with any gear; the last 7 bosses (Military + Construct + Frostwyrm Lair) require 232+ iLevel. The hardest boss in 25 normal is Kel'Thuzad (3 phases, requires CC).

Attunement

Naxxramas has no attunement in WotLK 3.3.5a. You can walk into the raid at 80 with no prerequisite questlines. The only requirement is being level 80.

Recommended gear for Naxxramas 25 normal

Minimum: iLevel 200+ (fresh 80 with quest rewards is enough for the first 8 bosses). Recommended: iLevel 226+ (Emblem gear + crafted epics). Optimal: iLevel 232+ (Tier 8 / 9 mix from ToC 10).

A fresh 80 with 200 iLevel can clear the first 8 bosses (Spider + Plague) in quest reward gear. The last 7 bosses (Military + Construct + Frostwyrm Lair) require 232+ iLevel.

Boss 1: Anub'Rekhan (Spider Wing first boss)

Health: ~3.5 million HP (25-man normal).
Key mechanic: Locust Swarm — Anub does a 12-second channel that does massive shadow damage to all players. Move out of the swarm at the end of the cast.
Tactics: Tank at the center of the room. The off-tank picks up the adds (crypt guards) that spawn. Ranged DPS burn the boss.
Loot tier: 200 iLevel pieces, Tier 7 tokens for the spider wing.

Quick tip: Locust Swarm is a 12-second channel. Save cooldowns (Anti-Magic Shell, Divine Protection, Pain Suppression) for the end of the cast when the boss does burst damage.

Boss 2: Grand Widow Faerlina (Spider Wing second boss)

Health: ~3.5 million HP (25-man normal).
Key mechanic: Frenzy — at 30% HP, the boss does 100% increased attack speed. The tank must be ready to heal through it.
Tactics: Burn the boss from 100-30%. At 30%, the tank uses cooldowns to survive. The adds (Sacrifice of the Spider) need to be positioned in the center of the room.
Loot tier: 200 iLevel pieces, Tier 7 tokens.

Quick tip: The 30% Frenzy phase is the only mechanic. Pre-heal the tank and save cooldowns for the burst.

Boss 3: Maexxna (Spider Wing final boss)

Health: ~4.5 million HP (25-man normal).
Key mechanic: Web Spray — Maexxna casts a 20-second AoE incapacitate on all players. Every player must be webbed.
Tactics: Pre-position players in a circle. Web Spray puts everyone in cocoons. The off-tank + ranged DPS burst the boss while the tanks are webbed.
Loot tier: 200 iLevel pieces, Tier 7 tokens.

Quick tip: Web Spray is unavoidable. Burst the boss during the cocoon phase, because the tanks can't do anything.

Boss 4: Noth the Plaguebringer (Plague Wing first boss)

Health: ~5 million HP (25-man normal).
Key mechanic: Balcony phase at 75%, 50%, 25% — the boss teleports to a balcony and summons adds. The raid has 60 seconds to clear the adds before the boss comes back.
Tactics: Burn the boss from 100-75%. At 75%, the boss goes to the balcony. AoE the adds. Repeat at 50% and 25%.
Loot tier: 200 iLevel pieces, Tier 7 tokens.

Quick tip: The balcony phase is the only mechanic. Save cooldowns for the transition back from the balcony.

Boss 5: Heigan the Unclean (Plague Wing second boss)

Health: ~3.5 million HP (25-man normal).
Key mechanic: Dance phase at 20% — the boss does a Plague Dance that does 4,000 damage per second to anyone in the room. Players must run to the dance floor and back.
Tactics: Burn the boss from 100-20%. At 20%, the boss goes to the dance floor. The raid has to dodge the eruption patterns.
Loot tier: 200 iLevel pieces, Tier 7 tokens.

Quick tip: The dance phase is the only mechanic. The eruption patterns are scripted; learn the safe zones.

Boss 6: Loatheb (Plague Wing final boss)

Health: ~5 million HP (25-man normal).
Key mechanic: Healing buff — Loatheb gives all players a 30-second buff that increases healing by 200%. The raid must burst heal the tanks during this window.
Tactics: Burn the boss from 100-0%. The healing buff is a DPS race — you want to burn the boss before the buff runs out.
Loot tier: 200 iLevel pieces, Tier 7 tokens.

Quick tip: Loatheb is a healer DPS check. If your healers are good, you can burst the boss. If not, the boss heals faster than you can damage.

Boss 7: Instructor Razuvious (Military Wing first boss)

Health: ~4.5 million HP (25-man normal).
Key mechanic: Mind control — Razuvious controls 2 player pets (Death Knight ghouls, Shaman totems, or Priest MC). The pets are his tanks.
Tactics: The 2 pets are the tanks. The raid bursts the boss. The MC phase ends when the boss reaches 0% HP.
Loot tier: 200 iLevel pieces, Tier 7 tokens.

Quick tip: The pets can't be damaged by normal attacks. Only the boss takes damage. The MC'd players are immune during the phase.

Boss 8: Gothik the Harvester (Military Wing second boss)

Health: ~3.5 million HP (25-man normal).
Key mechanic: Wave event — Gothik summons waves of undead for ~4 minutes. The raid must clear the waves. At the end, Gothik becomes active.
Tactics: Phase 1 (3 minutes): clear the waves. Phase 2 (1 minute): burn Gothik.
Loot tier: 200 iLevel pieces, Tier 7 tokens.

Quick tip: The wave event is scripted. Pre-position tanks for the waves; pre-heal the raid for the burns.

Boss 9: The Four Horsemen (Military Wing final boss)

Health: ~3.5 million HP each (4 bosses) (25-man normal).
Key mechanic: Mark — each Horseman marks a player. If the marked player is the only one on a Horseman, they take massive damage. The marked player must be spread.
Tactics: Tank 1 Horseman each. The marked player must be on a separate Horseman, not the tank.
Loot tier: 213 iLevel pieces (this is the first piece of Tier 8 loot).

Quick tip: The mark mechanic is the only tricky part. Pre-position marked players on a separate Horseman.

Boss 10: Patchwerk (Construct Wing first boss)

Health: ~7.5 million HP (25-man normal).
Key mechanic: Hateful Strike — the boss hits the top 3 threat targets. The tank must be the highest threat, but the off-tank must be second.
Tactics: Burn the boss. The tank and off-tank must manage threat so the boss always hits them.
Loot tier: 213 iLevel pieces, Tier 7.5 tokens.

Quick tip: This is a tank-and-spank fight. The boss does no AoE. Just burn.

Boss 11: Grobbulus (Construct Wing second boss)

Health: ~5 million HP (25-man normal).
Key mechanic: Slime Spray — Grobbulus sprays a slime on a player. The slime grows. The raid must kite the slime to a green circle.
Tactics: Burn the boss. The slime target runs to the green circle. Slimes in the green circle give raid-wide damage buff.
Loot tier: 213 iLevel pieces, Tier 7.5 tokens.

Quick tip: The slime target must NOT move the boss. Pre-position the green circle near the tank.

Boss 12: Gluth (Construct Wing third boss)

Health: ~6 million HP (25-man normal).
Key mechanic: Decimate — Gluth fears and one-shots all players below 50% HP. The raid must keep everyone above 50%.
Tactics: Burn the boss. The tanks must be above 50% HP. The adds (zombies) must be off-tanked.
Loot tier: 213 iLevel pieces, Tier 7.5 tokens.

Quick tip: Decimate is a healer check. Keep everyone above 50% HP. The zombies are off-tanked.

Boss 13: Thaddius (Construct Wing final boss)

Health: ~7.5 million HP (25-man normal).
Key mechanic: Polarity Shift — Thaddius alternates between positive and negative charges every 30 seconds. Players of the same charge damage each other, players of opposite charges heal each other.
Tactics: Phase 1: Stand on the pads, avoid the boss. Phase 2: Burn Thaddius while avoiding the charge mechanics.
Loot tier: 213 iLevel pieces, Tier 7.5 tokens.

Quick tip: Polarity is the hardest mechanic in Naxxramas. Pre-position players on the correct pad.

Boss 14: Sapphiron (Frostwyrm Lair first boss)

Health: ~9 million HP (25-man normal).
Key mechanic: Air phase — Sapphiron flies and does Blizzard + Frost Breath. The raid must be 10+ yards apart.
Tactics: Phase 1 (100%): tank and burn. Phase 2 (air): spread 10+ yards. Phase 3 (ground): burn.
Loot tier: 213 iLevel pieces, Tier 7.5 tokens.

Quick tip: Spread out for the air phase. Stack for the ground phase burn.

Boss 15: Kel'Thuzad (Frostwyrm Lair final boss)

Key mechanic: 3 phases with 25 adds per phase. The raid must CC the adds and burn the boss.
Tactics: Phase 1: CC 25 adds. Phase 2: kill 25 adds. Phase 3: kill 25 adds + burn the boss.
Loot tier: 213 iLevel pieces, Tier 7.5 tokens, including the T7.5 set tokens and Scepter of the False Prophet (a BiS caster weapon).

Quick tip: Kel'Thuzad is the hardest boss in Naxxramas 25 normal. The CC chain is mandatory. Most guilds wipe 2-3 times on first clear.

The fastest Naxxramas 25 normal clear path (2026)

The fastest guild progression path in 2026:

Day 1: Clear Spider Wing (3 bosses). 30 minutes.
Day 2-3: Clear Plague Wing (3 bosses). 1 hour.
Day 4-5: Clear Military Wing (3 bosses). 1 hour.
Day 6-7: Clear Construct Wing (4 bosses). 1 hour.
Day 8-10: Clear Frostwyrm Lair (2 bosses). 1-2 hours.

A new guild can expect 8-10 days to a full Naxxramas 25 normal clear in 2026. A veteran guild with full pre-BiS players can do it in 1-2 hours.

The path to The Immortal achievement (25-man no-death)

The Immortal is the "skill check" achievement for 25-man raiders. To earn it, you need to kill every Naxxramas 25 boss in a single lockout, with no player deaths.

The Immortal rules:

All 15 bosses in one lockout.
Zero deaths (any class, any reason, including disconnect).
The lockout can be saved (you can have multiple nights of progress, but the achievement completes when the last boss is killed in the same lockout as the first boss).

Time to complete: 1-3 lockouts (4-12 hours) of focused raid.

Difficulty: Hard. Sapphiron and Kel'Thuzad have wipe mechanics that are hard to recover from. The most common wipe points are:

Heigan's dance phase (player stands in the eruption).
Thaddius's polarity phase (player on wrong pad).
Sapphiron's air phase (player too close to another).
Kel'Thuzad's adds (overwhelming the raid).

Reward: Title "the Immortal" + tabard of the Frozen Champion.

If you're preparing for Naxxramas 25 on WoW Forever in 2026:

Pre-raid BiS gear first — see the WoW Forever Pre-Raid BiS Gear List for Every Spec (2026) guide.
Sons of Hodir Exalted for the shoulder enchant — see the WoW Forever Reputation Guide (2026).
Practice the first 8 bosses on alts first — they're a clean ramp-up.
Plan a full clear night (2-3 hours) with 20-25 players.

Once you kill Kel'Thuzad, you'll have Tier 7.5 set pieces for most specs and the start of your pre-ICC BiS. That's the milestone before ICC 25 normal.

Plan 8-10 nights. Get the Tier 7.5 set. Then move to Ulduar (the next raid) and eventually ICC 25 normal.
