Shadowtentacle

Based on game build 714014 | Last updated: 2026-03-07

Overview

shadowtentacle is a transient projectile prefab used as a boss attack in DST, specifically fired by the Ruins Bat (and potentially other sources). It manifests as a semi-transparent, slow-moving tentacle with shadow traits that damages targets on contact, reduces nearby player sanity, and automatically removes itself after 9 seconds. It is non-solid (due to SetPristine) and lacks physical collision for the player.

Usage example

This prefab is not manually instantiated by modders. It is created internally by entities like ruins_bat and slingshotammo. A typical internal instantiation looks like:

local tentacle = SpawnPrefab("shadowtentacle")
tentacle.Transform:SetPosition(x, y, z)
tentacle.owner = some_entity
tentacle.components.combat:SetDefaultDamage(new_damage)

Dependencies & tags

Components used: health, combat, sanityaura, lootdropper, physics, transform, animstate, soundemitter, network Tags: Adds shadow, notarget, shadow_aligned.

Main functions

The shadowtentacle prefab does not expose custom public methods beyond standard component APIs. Its behavior is configured via component setters during instantiation in the fn() constructor. All logic is handled by attached components and the state graph (SGshadowtentacle).

Events & listeners

The shadowtentacle prefab does not register or emit any events directly. It relies on its components (combat, health) and the state graph for internal event flow.
