Wormwood Vined Debuff

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

Overview​

wormwood_vined_debuff is a_prefab that functions as a combat debuff effect — specifically, a rooted vine that attaches to a target entity. It is instantiated by Wormwood's abilities and attaches to the target using a follower system tied to a named symbol. The prefab adds a debuff component (enabling integration with the debuff system), a timer component (to automatically terminate the effect after a fixed duration), and ensures the target becomes rooted via the rooted component. Upon attachment, it deals initial damage to the target and listens for events that should prematurely end the effect (e.g., target death, flight state, removal).

Usage example​

This prefab is not added directly by modders but is spawned internally by the game (e.g., when Wormwood uses a specific ability). However, if a modder wishes to replicate its behavior for testing or custom abilities, they would do something like:

local inst = MakePrefabInstance("wormwood_vined_debuff")
inst.GUID = TheNet:GetServerGUID() -- Required for proper network sync
local target = some_entity
inst.Follower:FollowSymbol(target.GUID, "root_sym", 0, 0, 0) -- Followed via debuff.SetChangeFollowSymbolFn

Dependencies & tags​

Components used: debuff, timer, rooted, combat, health, transform, follower, animstate, network
Tags: Adds "FX" and "NOCLICK" to the instance. Uses target.components.rooted to add/remove source.

Properties​

No public properties are exposed by this prefab. All internal behavior is encapsulated in event handlers and debuff callbacks.

Main functions​

OnChangeFollowSymbol(inst, target, followsymbol, followoffset)​

  • Description: Callback used by the debuff component to update the follower's target symbol and offset during runtime (e.g., on state change). Attaches the debuff FX to the target’s specified symbol.
  • Parameters:
    • inst: The debuff instance (self).
    • target: The entity being debuffed.
    • followsymbol: The symbol name to follow (string).
    • followoffset: A vector offset (x, y, z) relative to the symbol.
  • Returns: Nothing.

OnAttached(inst, target, followsymbol, followoffset)​

  • Description: Invoked when the debuff is first attached to a target. Sets parent relationship, adds rooted source, registers cleanup listeners, and deals initial damage.
  • Parameters: Same as OnChangeFollowSymbol.
  • Returns: Nothing.
  • Error states: Attaches a rooted component to the target if missing. Ignores damage if target is dead or lacks combat.

OnDetached(inst, target)​

  • Description: Invoked when the debuff ends. Removes the root source, plays detachment animation, and schedules the prefab for removal.
  • Parameters:
    • inst: The debuff instance.
    • target: The previously debuffed entity (may be nil/invalid).
  • Returns: Nothing.

OnTimerDone(inst, data)​

  • Description: Timer callback. Terminates the debuff when the STOP_TASK_NAME timer expires.
  • Parameters:
    • inst: The debuff instance.
    • data: Table with timer name; checked against "stop_vined_debuff".
  • Returns: Nothing.

Events & listeners​

  • Listens to:
    • death, enterlimbo, teleported, onremove on target — all terminate the debuff.
    • newstate on target — terminates debuff if target enters a state with tag "flight".
    • animover on self — triggers self-removal after the spike_pst animation completes.
    • timerdone — triggers debuff termination if timer name matches "stop_vined_debuff".
  • Pushes: None (this prefab does not fire custom events).
