ANCIENT VOWS

I know there are other threads on Reddit about this, however there have been multiple issues with this quest and the main on being on how to get the relics to drop. I have obtained both with no mind in another play through but now on my new build I have no idea how to get the kabala relic. The sun relic I have gotten with ease on three characters in the bone pits of the mastodon. I know the kabala relic is in keth and on a Reddit post I saw a guy say he had to play keth 14 times through to get the relic drop from a random mob. I am currently on my 7th play through of it while dripping my guy out in item rarity % and no luck. If anyone has any idea or tips on this quest please share. I am well past it now but just having that pesky little shit of a quest note on my screen is driving me nuts. Thank you.
