Instance Overview
The Ring of Acid starts out like the others; the raid must progress through several mobs which all require coordination, crowd control, and two tanks on separate targets before the raid reaches the main boss.
When the raid group reaches Iorweth, the fight has several stages. Iorweth spawns several adds which must be controlled by the tanks to keep the healers alive. He will then spawn two large troll which will need to also be tanked in the traditional manner. Here is where the 'acid' comes in: The entire room will fill with acid. ALL members of the raid must run in circles AND jump in order to avoid being killed by the acid. There are also acid pools which bubble up, causing extra damage. Stopping, even for a one second, will most likely cause a member of the raid to die. After the acid retreats, continue DPS on the trolls. It is advisable that the main tank kill the troll he is holding first, so he can recover in time to tank the boss. Once the trolls die, Iorweth will become damageable for a short time and then the adds start again. Repeat this process several times until Iorweth is defeated.
Challenge
In order to complete the Challenge quest, you quickly need to kill Iorweth's friends (2 Avancs, 2 Dragonets 2 Trolls), as soon as he calls out for them. Also make sure to not get coved with acid (as soon as the water level rises), or hit by any acid geysers. In both cases the challenge will fail.
