Paladin Tank soloes Magtheridon in his Lair.

Improved self-heal by Talents:
- Protector of the Innocent
- Eternal Glory

Glyphs:
- Glyph of Seal of Insight
- Glyph of Word of Glory

I positioned myself in the corner so I won't get kicked around by his earthquake and so the adds wouldn't hit me in the back. This also prevents Magtheridon from bugging and suddenly despawning in midair.

Also Used a Damage Weapon, Trinket and Flask to increase the damage done, or else I would have hit the enrage timer of 22 minutes.
