when i use /vampirism eye only fangs changes ( from 0 to 7). If i write 8...25 no result
Command /vampirism fang(s) does not exist.

Add /vampirism fangs and review the implementation of /vampirism eye

I'm sorry for my bad english.

Commands had the same name 🙈
Thank you for reporting

That is not a correct Forge version. It should look like this: 1.14.4 - 28.2.0

fangs changes ( from 0 to 7). If i write 8...25 no result

There are currently "only" 8 fang types, so anything beyond 7 won't work.
