Elder Staff Mod - Avada Kedavra

A powerful magical wand for Lethal Company inspired by Harry Potter. Cast the Killing Curse on enemies and players - but beware the Dementor that may come for your soul!

Features

The Elder Staff

• Avada Kedavra: Instant-kill spell with green lightning VFX, muzzle flash, impact explosion, spark trail, afterglow, and death glow effects
• SphereCast Detection: Reliable hit detection with 0.5m radius
• Buyable in Shop: Purchase from the terminal (configurable price, default: 1 credit)
• Spawns as Scrap: Also found as loot on all moons (configurable rarity)

The Dementor

After each spell cast, there is a configurable chance (default: 20%) that a Dementor spawns:

• 3D Grim Reaper Model: Dark, menacing appearance with HDRP-compatible materials
• 5 Particle Systems: Head smoke, wisps, face cloud, body smoke, and hem wisps for a truly terrifying look
• Spawns from Random Direction: 10-15m away, you never know where it comes from
• Hunts the Caster: Follows the player who used the staff, getting faster over time
• Dementor's Kiss: 6-second cinematic where the Dementor extracts your soul - player is lifted, stunned, and killed
• Staff Sacrifice: Drop the staff to save yourself - the Dementor destroys it in a purple magical explosion

Atmospheric Effects (while Dementor is active)

• Frost Overlay: Screen edges darken with blue frost as the Dementor approaches
• Cold Breath: Visible breath particles appear near your camera
• Light Flickering: Nearby lights dim and flicker (restored after Dementor leaves)
• Player Slowdown: Movement speed decreases the closer the Dementor gets
• Audio Distortion: Low-pass filter dampens all sounds
• Whisper Audio: Eerie whispering sounds that get louder with proximity
• Dark Trail: Trailing dark wisps behind the Dementor as it moves

Multiplayer

• Full Network Sync: Dementor is visible on all clients via ServerRpc/ClientRpc
• Team Warning: Nearby teammates experience insanity increase
• All players need the mod installed for full experience
