Old Kingdom

Nadox: This boss is a DPS check. He summons adds that can be ignored until a guardian spawns, making Nadox and the bugs immune. Burn down a few adds before immunity, then focus on the guardian, and finally return to Nadox. Pull adds off the healer and kill them quickly.

Prince Taldram: Beware of flame spheres and health drain. Dodge the 3 moving flame spheres by running away. When he drains a player, DPS him to free them. Stack up when he vanishes, as you cannot heal the drained player.

Jedoga: To counter her enrage from eating a sacrificed minion, you can either DPS the chosen minion down before it reaches the middle (use aggressive pets and AoE) or let it be eaten. If eaten, spread out, taunt Jedoga to let the buff wear off, and consider disarming her.

Amanitar: Located left of the Jedoga room. AoE tanking areas of mushrooms, keeping some healthy ones. The tank must watch for the 'Mini' debuff and kill a healthy mushroom. Avoid poison mushrooms, but eating a healthy one grants a 100% damage buff.

Herald Volazj: The main challenge is surviving the 'Insanity' spell. Increase survival chances by having only one healing class, unequipping weapons before Insanity, sending someone to die first, or casting damage-reducing spells for your clone. Stun and DPS the healer clone first, then follow the DPS chain, and finally kill the tank clone.
