Nex Leech Utility

A RuneLite plugin that helps you efficiently leech loot from Nex by securing the minimum 25 damage for loot eligibility with the least effort, while staying safe.

Features

• Per-kill damage tracker — an overlay showing your own damage and contribution this kill (e.g. 25 (0.5%)), turning green once you reach the 25-damage loot threshold and red until then. Also shows your drop rate (1/N from contribution) and the player count, and persists after the kill so you can read the result.
• Minion vulnerability highlighting — Fumus, Umbra, Cruor and Glacies are outlined faint red while invulnerable and hard green the instant they become attackable (driven by Nex's "<minion>, don't fail me!" callouts), resetting when the kill ends. Colours are configurable.
• Starting minion + leech-rotation warnings — pick the minion you start on (e.g. Umbra to skip Fumus). A prominent centred warning announces when that minion — or any later one, if you still need damage — is about to become vulnerable, with a countdown (seconds or ticks), then switches to "ATTACK NOW" once it's live. Warnings stop once you've reached 25 damage.
• Focus grab — optionally bring the client window to the front when the warning fires, so you don't miss the hit while tabbed out.
• De-prioritized minion attack — removes left-click Attack on a minion while it's invulnerable so you can't misclick it; left-click Attack returns the moment it becomes attackable.
• Optional blood-reaver highlighting — reavers also count towards your damage.
• Low HP / prayer alert — optionally flash the screen with a configurable message (e.g. EAT! / DRINK PRAYER POT) when HP or prayer drop below configurable thresholds (default 60 HP / 50 prayer). Stays up until the stat recovers, or for a set number of seconds.
• Hide players — entity-hider style; hide other players while inside the Nex room to reduce clutter (your own character is kept).
