Bullseye

Despite its name, lock on does not actually lock on to the target. Instead, it increases the damage that the target takes from lightning and dark orbs. I rarely find myself taking this card, as it is difficult to guarantee that you are hitting the right target or that you will have channelled enough orbs of the correct type for this to actually be effective. In theory, it can significantly increase a dark orb’s damage, but being able to cast this and evoke the orb on the same turn and on the right target is unlikely.
