Shark Keen Scent

[shay7815]

Will a shark be able to scent the diffrent between mirror image and the real one?

[VoxRationis]

The difference between keen and regular scent is merely maximum range. Regular scent can only pinpoint a foe by using a move action while within five feet of them, but it is possible. So yes, once the shark is next to the cluster of images, it should be able to tell which one is real.
