I've made my own Kiss the Void bot for Carbon similar to the built in one, but I use my own because you don't need Tendurrr and it's as fast. It joins the next room when you have the needed items.
It farms 80 Fragments of Chaos, 8 Broken Betrayal Blades and then turns in the quest.
I believe someone has made a similar bot.
Manually buying Tendurrr back from the buy back shop.
100th post?! Lets celebrate!
If you're interested let me know, I may release it if anyone would find it useful,
