This mod allows you to upgrade the personal crystal independently of Kreia. That way you can do that even after Kreia becomes unavailable.

The idea behind this mod is that if this crystal you get on Dantooine is so unusually responsive to you, why do you need someone else to keep it attuned? As I see it, the reason is Kreia's being the manipulator and control freak that she is. Most likely she wanted to seem even more indispensable to the Exile. Each time he runs to her with the crystal, it's a subtle reminder that he gains power, but through her.

However, what if our Exile was perceptive enough to pick up on the procedure himself...?

Therefore, with this mod, you can attune the crystal at a workbench, without Kreia's help. However, you must have enough Wisdom (16 or more). That stands for the Exile having sufficient understanding of the Force and of his own connection to the crystal.

Hint: if you're playing a combat-oriented character with low Wisdom, you can still meet the Wisdom check with some Wisdom-increasing items and/or Force Valor.

This mod changes something I originally thought was rather odd, that you couldn't change the alignment of a crystal that is attuned to you in itself, and that someone who is, in fact totally neutral in alignment has to change it for you. Why shouldn't you be able to do your own work?
Also, it's very useful when dealing with the alignment changes post-Dantooine return, for example killing your party members on Malachor. Having your weapon attuned to you at such a critical moment is very important, something I believe Obsidian missed. Overall, an excellent mod and one I would recommend.
