Spectral Veil

The Spectral Veil is a Revengeance Mode-exclusive Post-Moon Lord rogue accessory that drops from Signus, Envoy of the Devourer. While equipped, pressing the key teleports the player to the position of the cursor at the cost of 25% of the player's stealth and inflicting the Chaos State debuff. If the cursor's position is over 20 tiles away, the player will be teleported 20 tiles in the direction of the cursor as long as no blocks are in the way. After a successful teleport, the player gains 2 seconds of immunity frames. If the player gets hit during invulnerability, stealth regenerates to full and the invulnerability is removed. Teleports are disabled for as long as the player is inflicted with Chaos State.

Trivia

 * The Spectral Veil was implemented based on a community suggestion made by Hyperin on the mod's Discord server, where it was called "Signus' Cloak".
