Adaptive Blade
Weapon (shortsword), legendary (requires attunement)
This sword appears ordinary in every way. In fact, it is a legendary magical weapon imbued with the ability to adapt itself to seek it's wielder's approval. It learns from its wielder's actions and choices, becoming more powerful and versatile over time.
The sword begins as a very plain, ordinary shortsword. As it grows, it's appearance slowly changes to suit it's holder. A paladin's Adaptive Blade might be intricate and golden, while a necromancer's could be a gnarly looking and made of bone.
The blade starts with one adaption point. Whenever you gain a level while attuned to the blade, it gains an additional point. During a long rest, you can spend any number of points to make an adaptation from the adaption table to the blade permanently. If a adaptation has a prerequisite listed, the blade must already the prerequisite to obtain the new adaptation. The new adaptation always replaces the prerequisite adaptation. Each adaptation can only be gained once, unless otherwise stated.
Once a creature has attuned to the blade, and the blade has at least one adaptation, the blade refuses to attune to other creatures. One month after the attuned creature dies, the blade loses all adaptations and reverts back to it's original form.
GM Note: GMs are encouraged to work with players to create custom adaptions beyond those provided.

Creation Notes
Inspiration words: learns and approval. It's weapons week!
I uh, went a bit overboard on this one, and didn't really have time to give it to normal balance polishing. I may have to return to this one at the end. Finishing weapons week with a bang, though!
