Wither Symbiote
Inspired by AltarSMP.
Base item: Netherite Sword
Command: /withersymbiote [player]
Permission: customweapons.withersymbiote (default: op)
Resource Pack: Install the AltarSMP Texture Pack - this plugin set is built around it and looks/sounds as intended with it installed.
Cross-Plugin Detection (/weapons)
Every AltarSMP weapon plugin registers /weapons [player], which hands you one weapon from every other AltarSMP plugin currently installed and enabled - a live check each run, nothing to configure.

Abilities & Triggers
| Trigger | Ability | What it does |
|---|---|---|
| Right-Click | Infection | Afflicts your target (within 5 blocks) with Wither II for 3 seconds. |
| Shift+Right-Click | Rampage | Grants Strength II and Speed II for 8 seconds each and heals you 4 health, fueling an aggressive push. |
Notes
- The weapon is bound to the player who receives it via a persistent NBT tag, so lore/name changes won't break ability detection.
- The activating player is never hit by their own ability's damage, knockback, or negative effects, even for area attacks, explosions and travelling projectiles/waves.
