Debuff

For the purpose of this article, debuffs are temporary effects that reduce the statistics of players or NPCs, usually affecting their movement speed, incoming damage, outgoing damage, or other.

End game raid debuffs

The below table is intended as a list of "endgame" debuffs in DDO. These typically reduce the defences of enemies, and thus raise party DPS. Descriptions may not exactly match in game, or be consolidated where effects are named differently but coded the same.
