Server Guide

Installation

The mod goes on the server and on every client, with Fabric API. Mod Menu and EMI are optional and client-only.

Terrain

• /gamerule jjkTerrainDamage false turns off all terrain damage from techniques.
• Adventure mode, spawn protection and mobGriefing (for NPCs) are also respected.
• Domains and the Veil keep a temporary copy of the terrain in <world>/jjk_domains/ and always restore it, even if the server crashes. The folder clears itself.

Balance: config/jjk.json

• Created on first start with every value in the mod (damage, costs, cooldowns, chances, curse spawning…). Each version adds new keys without touching the ones you changed.
• Quick multipliers in the Multiplicadores section: DAMAGE (all technique damage), COST (CE costs), COOLDOWN (cooldowns), PLAYER_DAMAGE_TAKEN (damage players take), and one per technique (TECHNIQUE_DAMAGE) and per ability (ABILITY_DAMAGE, using the Spanish name: "Azul": 1.5 for Blue).
• /ce config reload reloads it without restarting. Max health changes need a restart.
• Deleting a key resets it to its default. If the file has an error, the mod uses the defaults and doesn't overwrite it.
• The server sends its balance to each player on join, so the K screen shows the server's numbers.
• In singleplayer you can also edit it from K → Settings → Mod balance (or Mod Menu's Configure button). On a dedicated server that screen is read-only.
