First, you should start with [i]two[/i] elemental cores. If you only want Earth, you could start with two Earth cores.

Second, Stone Sense has to have a range limit, because there's a limit on how far you can extend your magic. For now, a kilometer should be about as far as you can stretch it, and the image should get weaker the further away it is from you. Also, you may not be able to see through earthen materials that are already infused with magic more powerful than your own.

Third, Earth Glide is kind of awkward and vague. You make it sound like some limited form of intangibility that only works inside earthen materials, which isn't really possible. Due to how intangibility works, you either clip through all physical matter or none. True intangibility also usually needs the Aether element, or at least Light or Dark; you can't really pull it off with Earth. I'd say you should change it so that the ability uses magic to cause the earth in your character's immediate vicinity to flow like water, so that he can "swim" through it. With this change, the ability [i]would[/i] create some detectable ripples, but it would no longer affect the user if the rock he is in gets split apart. Also, you should know that the ability might not work well on earth that's already infused with magic more powerful than your own, just like the previous ability, though you don't have to add this to the description.

I agree with your judgement. I'll add the character to the character list with the proposed changes.
