This is a datapack, so it is applied through the world rather than each player's game. The server controls the spell balance, which keeps it the same for everyone.
Applying It on the Server
1. Stop the server and make a backup of the world folder.
2. Place the datapack in the server world's datapacks folder.
3. Start the server. As an operator, run /datapack list to confirm the pack is enabled.
4. If it is not enabled, turn it on with /datapack enable and the pack name shown in the list. Then run /reload.
The main Death Knights mod must be installed for the spells to exist. The balancing pack only adjusts their stats.
Telling Your Players What Changed
Share a quick summary so Unholy players know what to expect:
- Lesser Festering Strike: higher spell power for magic and melee, cooldown cut in half.
- Death Coil: faster bolts that hit much harder.
- Epidemic: a big burst of direct impact damage.
- Death Grip: shorter cooldown, so pulls happen more often.
Keeping Things Fair
- If Unholy players start outperforming everyone else, edit the config values for the other spells to close the gap. Then run
/reload. - Announce balance edits before applying them so players aren't surprised mid-fight.
- Keep a copy of each version of the pack you use. This lets you roll back if the group dislikes a change.
