You will encounter high level Kizoars as well as other possible mobs during this rite. It is recommended that you are a rather high level in either elemental magic or in a melee skill. While it is possible to do this rite in a group, if someone else in your team has the Kizoar Rite and is up to the current stage of locating Kizoars, your mission may bug requiring you to start the rite mission again from Ana Ryon.
All prerequisite missions are from Bechi Chiado and Aniche Anigno. Aniche Anigno may also be located at Southeast Trade Post
Travel to Altami Wood and enter the Kitin Lair to to find Ana Ryon and begin the mission. She'll instruct you to visit Pecho Cuigno in Upper Bog. He tends to move around ending up in the maze section in the south to the border of Fleeting Gardens. It's suggested to talk to him when he's wandering around the upper areas to prevent getting killed needlessly!
He'll then assign you five missions, one for every land of Atys:
At each of these locations you'll encounter either a level 236 Great Kizoar or a level 236 Lethal Kizoar.
Each location you visit will spawn one of these nearby, which you will then need to kill to continue your mission in the current land. You won't have to loot them except for a Lethal Kizoar which you'll receive goo meat and a Lethal Kizoar Wing (automatically placed in your inventory).
During my rite, I found the lethal kizoars only at:
Once you have all five Lethal Kizoar Wings, return to Pecho Cuigno to continue the main mission.
He'll hand you a report (automatically placed in your inventory) to return to Ana Ryon.
Show the Report to her to then recieve a new mission to locate and kill a Lethal Kizoar in the Lair.
The Lethal Kizoar can be found with the other group of Kizoars that roam around in the north east of the Cattle Room. If you're having trouble finding it, remember to set up a macro for easy targeting!
Once complete, return to Ana Ryzon for the last time.
Congratulations! You've completed the rite!
