"Keep the enemy away as long as you can, and pick them off one at a time. One-on-one battle is for fools and knights!"Fatigue is a second level death magic spell in Heroes of Might and Magic IV that costs three spell points and reduces the target's speed and movement in battle by half.
This spell sounds similar to Order's Slow, but it is inferior for one reason; Slow will affect any creature not immune to magic altogether, while fatigue is a mind spell, and only works on creatures that can become fatigued. Elementals, constructs, and the undead ignore one more weapon in the Necromancers' arsenal.
Water elementals can cast this spell in combat.
