Xp Formula

# Item Attributes Version: 1. 4. 1-legacy Minecraft: 1. 20. 1 Loader: Forge ## What this mod does Item Attributes lets players (and admins) customize any item vanilla or modded using XP levels as currency. Everything is stored in the item's own NBT, so no new items, blocks, or recipes are added; a plain diamond sword or leather boots can become a build-defining piece of gear. The system has four layers, roughly in order of power: 1. Attributes set attack damage, attack speed, attack range, or armor to an exact value. 2. Effects attach vanilla or modded potion effects that trigger while held, while worn as armor, or on a melee hit. 3. Rank every attribute and effect on an item counts as one "modification." Enough of them pushes the item's rank from E all the way to SSS. 4. Flux Cores once an item hits SSS rank, it can be assigned one of 12 rare cores (7 for weapons, 5 for armor), each with its own passive kit, and in several cases, unique abilities. Everything is priced in XP levels, and almost every number in the system costs, drop rates, cooldowns, damage, terrain destruction is server-configurable. --- ## Progression ### Rank `RankUtil` counts how many real modifications are on an item (Damage/Speed/Range/Armor each count as one if set, plus one per Hold/Armor/Hit effect): | Modifications | Rank | |---|---| | 0 | E | | 1 2 | D | | 3 4 | C | | 5 6 | A | | 7 9 | S | | 10+ | SSS | Reaching SSS for the first time on an item automatically rolls it a random Flux Core (from the correct pool for that item's type weapon cores for weapons/tools, armor cores for armor pieces) and grants the God Forge advancement. ### Cost Every modification costs XP levels, computed per-attribute and multiplied by a global cost multiplier (default 2x): - Damage/Speed/Range/Armor: cost scales with the requested value (per-point cost, configurable). - Hold/Armor/Hit effects: base cost per tier-1 vanilla effect (default 30), doubled for modded effects, and multiplied per amplifier tier above 1 (default 3x per tier). - Setting a specific Flux Core costs a flat amount (default 500); rolling a random one costs less (default 50). - An optional max level cost cap can clamp any single modification's cost down to a ceiling, regardless of how expensive the raw calculation would otherwise be. --- ## Weapon Flux Cores Rolled or set on whatever is in the mainhand or offhand slot. Only one weapon core is active per item; Godfather can only exist once server-wide (see below). | Core | Default roll weight | Passive kit | |---|---|---| | Everchosen | 35% | Regeneration II while held. On hit: true damage (bypasses armor/resistance/invulnerability). | | Juggernaut | 25% | Resistance II, Health Boost II, Absorption II while held. On hit: weaker true-damage explosion. | | Angelic | 15% | Regeneration II + a 37-block "godly pressure" aura (Slowness/Wither on nearby hostiles). Hits deal true damage. | | Reaper | 14. 79% | Strength V, Speed V + god
