Emperor's Chains

Cost: 16m
Target: One ghost or multiple ghosts The necromancer claps his hands, and his Essence rings like a dull but very loud gong. When the sound strikes a ghost, the ghost becomes sluggish and has difficulty moving. All ghosts within 50 yards of the caster move at half speed (minimum one yard per tick) and double the Essence costs of all movement-related Arcanoi. Creation mutes the sound of the gong, reducing the range to 25 yards.

The caster may instead focus the spell on a single ghost in range. That ghost becomes unable to move at all, and the Essence costs of movement-related Arcanoi triple.
