1.20.1 forge. Ill update with more details once im back from Christmas.
I only tested one ability: the passive drawspeed increase. Making it work seems like a reasonably easy change since tetra adds an attribute for bow draw speed.

The official support for the mod on versions from 1.16.5 to 1.20.1 inclusive has been discontinued. However, the issue may be resolved by other users through a Pull Request.
