Magtheridon's Lair Boss Guides - TBC Classic

Magtheridon

Phase 1

Magtheridon remains innactive for the first 2 minutes.
DPS should kill as many Hellfire Channelers as possible during this time.
Interrupt
Shadow Volley
and
Dark Mending
.
When a Hellfire Channelers dies, all other Hellfire Channelers gain
Soul Transfer
.
Use
Fear
,
Banish
, and other forms of crowd control on Burning Abyssals that spawn.

Phase 2

Begins after 2 minutes.
DPS should kill any remaining Hellfire Channelers.
Everyone should avoid the
Conflagration
AoE.
Every 50 seconds, a
Quake
will knock everyone up for 7 seconds.
Every 60 seconds, Magtheridon will cast
Blast Nova
. Immediately interrupt this by having 5 players click on all 5 Manticron Cubes at the same time.
Two alternating groups of 5 players should be assigned to this task because channeling a Manticron Cube will place a 1 minute and 30 seconds debuff preventing players from channeling.

Phase 3

Begins when Magtheridon reaches 30% health. Everyone will takes 6k damage and be stunned for 2 seconds.
Make sure to avoid entering Phase 3 when a
Blast Nova
cast is about to go off.
Continue interrupting
Blast Nova
by clicking on all 5 Manticron Cubes simultaneously.
Everyone must avoid getting 1-shotted by the AoE ceiling collapsing on the floor.

Notes

Warlocks should use
Curse of Tongues
on the Hellfire Channelers to help with interrupts.
Mages and Paladins can use
Ice Block
and
Divine Shield
to avoid damage when entering Phase 3.
Hunter traps are helpful with controlling the Burning Abyssals.
