This is for those who want to know how to feed Pekka’s Ardun in Xenoblade Chronicles 2.
IF YOU KILL THE ARDUN BEFORE IT HITS LEVEL 99, IT IS GONE FROM THAT SAVE FILE!!! EITHER RESET IF YOU KILL IT ACCIDENTALLY OR TRY AGAIN FROM NEW GAME +.
There are 5 different feeding phases for the Ardun, and the Ardun will go up approximately 20 levels for each feeding phase. You can do this after any time you enter Torigoth. The level 99 unique monster that results from this is not aggressive and will not target you if you don’t attack it first.
Locations for collectibles are marked with a spoiler tag. Collectibles themselves are not marked.

** RELENTLESS ARDURAN, LVL 99 ** – Yer dun
Note: If you already unlocked Arduran in a previous playthrough, and if you feed it to full again, the Arduran will not show up like the previous Arduns did. It still has to be summoned by using the gravestone. Therefore, you cannot fight two Ardurans at once.
After defeating Relentless Arduran, a gravestone will appear for which you can summon it over and over again, similar to other Unique Monsters.
I’m open to suggestions for locations too if these current ones don’t work for you.
