With this spell, a competent riftwalker can create and control a rift which shadows an opponents body, leeching life energy into the dimensional rift. The rift shadow will increase in power the longer it is in existence. A true master of all types of rift entity can cause huge amounts of damage with this spell. There is also a chance that critical amounts of energy will be leeched from the target, some of which will be absorbed by the riftwalkers entity if they have completed 'The Grind'. Criticals consume a rift spark. This spell uses 2 rift sparks.
