D&D Stats Core

Adds six tabletop ability scores to players and mobs, then resolves combat with d20 attack rolls, crits, stuns, and on-screen dice checks.

Requires Minecraft 1.21.1 and NeoForge.

What it does

On first join you assign STR, DEX, CON, INT, WIS, CHA (27-point buy from a base of 8, plus a +2 / +1). Scores lock for that world. Mobs have their own sheets.

Attacks, checks, and saves are rolled on the server. The client only draws what happened: floating numbers, a gold die on a passed check, and a roll log in the top-left.

Combat

• Every swing and shot rolls a d20 vs armor class. Nat 20 crits. Nat 1 always misses.
• Damage is 1dN + modifier. Crits roll the weapon die twice.
• Axes, tridents, and maces can stun (STR vs CON) on a fully charged hit.
• Light / medium / heavy armor with real AC. Light keeps full DEX, medium caps it at +2, heavy ignores DEX. Below an item's STR requirement you keep the AC but attack at disadvantage and move slower.
• Shields add +2 AC. A raised shield only holds if the attack failed to beat that AC.
• Enchantments and potions use their own dice (Sharpness, Smite, Power, Fire Aspect, harming, healing, poison, wither, burning).

By default, failing the attack roll vs AC still deals damage (Minecraft-feel). Turn on failedAttackRollsMiss if you want a miss to cancel the whole hit.

Checks you can see

A passed check plays a dice sound, floats a gold die over that creature, and adds a line to the corner log — Charisma talk-downs, fire DEX saves, poison/wither CON saves, fall checks, brew checks, and the rest. Failures stay quiet.

Ability perks

HUD

Floating combat numbers, crit / stun / miss / block icons, corner roll log, mob health bars with portraits, inspect panel (I), and a character sheet keybind.

How to configure

Configs appear after the first launch:

• Server / world rules: config/dnd_stats_core-common.toml
• Your HUD: config/dnd_stats_core-client.toml

Edit, save, then restart the client (or the server, for the common file).

Datapacks (no code)

Drop files in a datapack (or override the ones in the jar). A file with the same path replaces the built-in default.

Example mob file (data/minecraft/dnd_stats_core/mob_stats/zombie.json):

{
  "strength": 13,
  "dexterity": 6,
  "constitution": 16,
  "intelligence": 3,
  "wisdom": 6,
  "charisma": 5
