Contagion Signal
Inspired by AltarSMP.
Base item: Echo Shard
Command: /contagionsignal [player]
Permission: customweapons.contagionsignal (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.
Crafting Recipe

Drop the ingredients into a crafting table in that pattern (. = empty slot) to get the Contagion Signal. Recipe can be turned off in config.
Enchantments
- Mending I
Not a melee weapon, bow, or armor piece, so it doesn't carry combat/defensive enchantments beyond Mending. Still unbreakable.

Abilities & Triggers
| Trigger | Ability | What it does |
|---|---|---|
| Right-Click | Pale Curse Beacon | Summons a floating beacon at your feet that pulses Poison to nearby entities over its duration, then disappears. |
| Shift+Right-Click | (none) | This weapon has no secondary ability. |
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.
