You mark a target for certain death

As part of this invocation you have to make a ranged touch attack against the target. The target is marked with an invisible mark of your patron(see invisible can reveal it). Any hit against this target now has a doubled crit range. You can only affect one creature with this invocation at any given time. When attacking the target you can choose to automatically threat a critical hit on the target, thus dispelling the mark.
