Remains in play. The enemy is infected with an atrophying canker that twists their limbs and withers their muscles. Pick one enemy unit on the battlefield that is not in close combat. Whilst the spell remains, the unit halves its Movement value (rounding up). If the unit is mounted, then the Movement value of the mount is halved. Flying creatures affected by this spell may only use ground movement but do not halve their Movement. Afflictions remains in play until the Sorcerer chooses to end it (which he can do at any time), it is dispelled, he attempts to cast another spell, or he is slain.
