With that in mind, you're well within the approvable constraints. If there's no other changes you'd like to make, I'll move right along.

For reference, something like being able to see in the dark isn't that strong, so it won't take up much space in your ability slots. If you wanted him to be able to see leylines or read the path of a spell before it's cast, that would be much higher rates. These are just examples of progression you might take, what you actually decide is up to you. Just bear in mind that you're not married to your level one abilities by any means once you've progressed.
