What was built

Added a full ability system that assigns one of ten themed abilities the first time a player joins. Each assignment is stored by UUID in abilities.yml and persists through restarts.
Implemented /ability (info), /ability use, and /ability cooldown so players can view and trigger their power. Actives respect the defined cooldowns and use effects/damage boosts tailored to each ability.
Created a configurable Reroll Tome (enchanted book, default name §dReroll Tome) with a shaped recipe (NNN/OOO/GGG for netherite ingot, obsidian, gold block). Right-clicking it rerolls the player’s ability and consumes the tome; recipe/item visuals can be customized in config.yml.
Added passives and actives per ability: Rampaging Fury kill stacks and bursts; Executioner execute hit; Blood Pact and Heart Reaver lifesteal models; Serene Aura ally buffs/cleanse; Overcharged Bliss potion duration boost plus absorption surge; Phase Error void/suffocation immunity with short phasing; Reality Break periodic buffs and hotbar scramble; Blood Offering health-for-damage trade; Soul Altar periodic healing pulse plus Armor Drain window.
Background tasks keep radius buffs (Serene Aura), periodic buffs (Reality Break), and scheduled healing (Soul Altar) running automatically.
Updated plugin metadata to mnokey with a concise description and default config for tome/ability tuning.

How to use it

Players are auto-assigned an ability on first join; run /ability anytime to see name, passive, active, and cooldown status. /ability use fires the active when off cooldown (Soul Altar can also be right-click activated).
Craft a Reroll Tome with the default recipe (top row netherite ingots, middle obsidian, bottom gold blocks) or adjust the recipe/materials/name in config.yml. Right-click the tome to consume it and reroll to a new ability.
Abilities stay bound to each player across sessions; death resets relevant stacks/buffs (e.g., Rampaging Fury stacks, temporary actives) but not the assignment itself.

Executioner’s “true damage” active is modeled as a large bonus hit; extreme armor or resistance may still soften it.
Phase Error uses a brief swap to spectator mode for 2 seconds to mimic phasing, which may be affected by server rules restricting that mode.
Reality Break’s hotbar scramble targets the nearest other player within the configured range and restores their original hotbar after 4 seconds.
Armor Drain reduces durability on each hit during its window; it respects armor that can take damage and won’t affect non-damageable gear.***
