Chimera Pet Quest

Overview

Wall of Slaughter NPCs offer 3 different pets: Feran Pet Quest and Murkglider Pet Quest in addition to this Chimera Pet Quest.

They involve killing trash mobs of a specific type and collecting 8 rare drops from them.

Speak with Chimera Tamer Trelak in the Wall of Slaughter. Beware, mobs summon and many see invis. Call of the Hero is disabled in this zone.
He will ask you to collect 4 Dragorn Gold Coin for him before divulging details about the rest of the quest.
Collect 4 of this semi-rare item and return them to Trelak unstacked to proceed.
Trelak will then give you a bag, and ask you to collect 8 no drop Chimera parts from the Chimera cave located on the outer perimeter of the zone.
After collecting all 8 parts, combine them in the quest-given bag to obtain Chimera Essence.

Take your Chimera Essence and find An Untamed Chimera. They are weak and KoS. Fortunately they go invulnerable and freeze when low on health.
At this point, give Chimera Essence to An Untamed Chimera to tame it and make it yours.

If you've made it this far, congratulations! You have successfully tamed a Chimera, yielding this item: Art of the Chimera to summon it and provide yourself with a beneficial buff.
Note** The buff persists after dismissing the pet - fret not.
