I kinda bumped into this concept and fell in love with it, so I started thinking further, thought up some playstyles, some unique features to it, etc.
Rather than just retyping everything out here, I just copy-pasted it from the notepad I used for it. It's still raw, but I think this entire concept has potential.
Hope you enjoy. Thoughts and feedback welcome.
F.A.

Psychic Spellblade - Psyblade for short.

Main Theme: Controlling your weapon through Psychic prowess, wielding it seperate from your character, combined with several Psychic spells.

Main Weapon: Chained Spellblade
- Chain is wrapped around the main arm of the player (-> Prince of Persia is a good visual reference),
blade is thrown and swung around using the chain and controlled using psychic powers.

Main attribute: INT
- Psychic powers are its main focus, thus Intelligence.
(No auto-attacks at range)
