Cloying Quagmire

Pick a friendly Maggotkin of Nurgle Wizard to cast this spell, pick a visible enemy unit within 18" of them to be the target, then make a casting roll of 2D6.

Halve the target’s Move characteristic until the start of your next turn. If the target’s Save characteristic is 3+ or better, subtract 1 from run rolls and charge rolls for that unit until the start of your next turn.
