This spell can be cast on an enemy unit visible to the caster and within 24". If successfully cast, the target unit is drenched in rain and counts as soaked for the rest of the game.

All soaked models suffer a further -1 modifier on their shooting to hit rolls, increased to -2 if the model's weapon has the armour piercing rule. If the unit does not fire using BS (a cannon, for example), then it may only fire if the player can first roll a 4+ on a D6 each turn. There is no additional effect for being soaked more than once.
