Bugged. What's listed here is the actual effect.
This spell can be seen as a half-assed Blind that only works on Ranged troops. Only really cripples the opposition if their ranged numbers are very vast and they don't have No Range Penalty. Otherwise you're better off using Blind.

On the contrary: Blind is more useful (assuming you have it) until you have expert water magic; then the mass effect of Forgetfulness is superior when the enemy has multiple stacks of range troops, especially with units that attack hand-to-hand at half strength.
