Gruul’s Lair Raid Guide (TBC Classic Anniversary) – Maulgar Strategy, Shatter & Growth Tips

Gruul’s Lair is one of the two Phase 1 25-player raids in The Burning Crusade Classic Anniversary. Featuring two boss encounters — High King Maulgar and Gruul the Dragonkiller — this raid serves as a gear and coordination check early in TBC progression. While mechanically simpler than Magtheridon, Gruul punishes poor positioning and scaling damage over time.

High King Maulgar

A council-style fight featuring Maulgar and four adds. Each add requires a specific tank and control strategy.

🛡️ Tanks

• Assign one tank per add
• Spell Reflect Krosh Firehand’s spells
• Keep Maulgar faced away from raid
• Prepare for Phase 2 (Maulgar enrage at 50%)

🩸 Healers

• Heavy spike damage on add tanks
• Watch Whirlwind targets
• Stabilize during Maulgar’s enrage phase

⚔️ DPS

• Follow strict kill order
• Interrupt heals and casts
• Avoid Whirlwind
• Spread during Phase 2

Gruul the Dragonkiller

A scaling DPS race where raid damage increases over time due to Growth. Positioning and Shatter management are critical.

🛡️ Tanks

• Main tank center room
• Face boss away (Cleave)
• Manage Hurtful Strike (second highest threat target)

🩸 Healers

• Tank damage increases every Growth stack
• Raid healing after Ground Slam
• Prepare big cooldowns after 8+ Growth stacks

⚔️ DPS

• Spread 8+ yards to reduce Shatter damage
• Collapse awareness after Ground Slam
• Max DPS early before Growth stacks ramp
• Manage threat carefully

        R     H     R

    M          T           M

        R     H     R

T = Main Tank (center)
M = Melee spread loosely behind boss
R = Ranged spaced around room edge
H = Healers spread between groups

Maintain 8+ yards between players.
After Ground Slam → reposition immediately.

Every 30 seconds, Growth increases Gruul’s damage by 15%. Most stable kills happen before 12–14 Growth stacks. After that, tank damage and raid healing become extremely difficult to sustain.

Recommended Kill Window

• Target kill time: 4:30 – 5:30 minutes
• Safe Growth range: 10–12 stacks
• Danger zone: 13–15 stacks
• Wipe territory: 16+ stacks

Raid DPS Targets

• Minimum total raid DPS: ~18,000–20,000
• Comfortable kill DPS: 21,000–24,000+
• Average DPS per damage dealer (15–17 DPS): 1,100–1,400+

How to Increase Kill Speed

• Use Bloodlust/Heroism early (before 6–8 Growth)
• Pre-pot and use second potion during burn
• Minimize Shatter movement downtime
• Ensure melee maintain uptime after Ground Slam
• Optimize threat so DPS can push safely

• Tier 4 Shoulder Tokens
• Strong melee DPS weapons
• High-value tanking shields
• Excellent physical DPS trinkets

• Boss Mods (DBM / BigWigs)
• WeakAuras for Growth tracking
• Threat Meter
• Raid frames with range indicators
• WCUI optimized UI Packs

Gruul’s Lair is a classic early TBC DPS race. Execute clean positioning, control Maulgar’s council, and push Gruul before Growth overwhelms your healers.
