☀The Must Obey spell is a continuous spell which forces your creatures to work more efficiently. This spell increases the speed of all of your creatures (similar to being slapped) and forces them to perform all of their tasks much more quickly for however long the spell lasts. The spell is similar to Call to Arms in that it is a continuously-running spell, and costs 25 gold per second until it is cancelled or the player runs out of money. This spell is very useful if one has a large amount of money or access to gems, but can be quite costly otherwise. If Creatures are angry while the spell is in action, they will not perform their Anger Job. In Dungeon Keeper FX, the spell also allows the player to force creatures to do jobs they hate.
