Ebony LogSwap

The Fabric mod Charm introduces unique ebony trees, but they don't spawn naturally in any biomes. Additionally, according to the developers, ebony saplings should be found in Woodland Mansion chests, but this feature also malfunctions—possibly due to conflicts with other mods altering mansion generation.

Another mod, Oh The Biomes You'll Go (BYG), also includes its own version of ebony trees. This datapack works with Polymorph to enable conversion between BYG Ebony Logs and Charm Ebony Logs.

It also fixes a known bug where Charm's ebony leaves don't drop saplings. Conversion recipes for both ebony sapling types are included for planting Charm ebony trees around your base.
