5 Megaera

Guide in short:
1. Face the head away from the raid to avoid breaths on the raid.
2. Avoid killing the Freezing Head on Normal and the Venomous Head on Heroic.
3. Stack in melee and use strong defensive raid cooldowns during  |cffffde00Rampage|r.
4. Dispel  |cffffde00Cinders|r outside of the raid group (preferably within 3 seconds on Heroic).
5. Move towards the back of the room when targeted with  Torrent of Ice (Heroic only).
6. Create distance between yourself and the impact zone of  Acid Rain (Normal only).
7. Tank-swap with every new head that spawns.
8. Cleave and interrupt Nether Wyrm|cffFFD100s|r when they spawn.
9.  Bloodlust on the 6th Rampage and kill the boss.
