Reading this scroll will unleash a powerful blast of mind magic. Any creatures within line of sight will turn against their companions and attack indiscriminately for 30 turns.

A scroll of discord can be used to create chaos in the dungeon. It it temporary, having a relatively short duration, and is therefore often best used on tightly grouped enemies. Discord warps perception. Creatures affected by the discord shed alliances and treat all other creatures as an enemy. It does not mean that discorded enemies are your make-shift allies or that they will not attack you as well.

Discord does not discriminate. It will turn your allies (temporarily) against you and each other. It's often best to make sure that allies are out of sight when you read the scroll, or suffer the consequences.
