Modifier Flags Reference

Complete list of all 303 modifier_flag constants. For the curated subset of flags most useful to scripters, see Types & Constants > modifier_flag.

Usage

if player:has_modifier_flag(modifier_flag.STUNNED) then
    -- player is stunned
end

Not every flag fires

The full list below is exposed for completeness. Some flags are populated reliably and broadly (e.g. STUNNED fires for almost every hard stun, INVISIBLE_TO_ENEMY fires for every cloak/smoke effect we've tested). Others may never fire even when the player is clearly in that state. Examples we've seen in testing:

• SLIDING may not be set while a player is sliding
• USING_ZIPLINE may not be set while a player is on a zipline
• IS_IN_CHARGE_MELEE may not be set during a heavy charged melee
• SLOWED and BURNING are inconsistent: some sources set them, others apply the effect via stat modifiers without ever tripping the flag

Some of these may turn out to be set by items or interactions we haven't tested. Always confirm a flag actually fires before relying on it. Use the Debugging Modifiers workflow with Modifier States logging enabled to watch the flag toggle while the effect happens. If it doesn't, fall back to player:get_modifiers() and match by name or token directly.
