Additionally. A small QoL update would be to add infinity books to the grey books in custom enchants. And remove the useless ones that have no value from the other sections I.E headless, glowing, telepathy, experience, ravenous, berserk
as to the first part. Thats a good idea. All you need to do is implement a limit of the amount that can be placed within fac land and it essentially eliminates that. 10-15 would be a good amount.
With the second part. There's far too much verticality in volcano to make pvp a satisfying...
Volcano being more worth it would also increase the need for it being remodelled for better pvp. The soul sand makes it horrific. I’d suggest changing it to stained clay or reaching out to the creative community for a new build
