I honestly thought about movement speed, but I didn't want the item to be too much like Zephyr. I figured Zephyr filled that position already, especially since it also has Tenacity to enhance mobility even more. The most difficult part was figuring out what Advanced tier item would be combined with the Chain Vest to give it movement speed. Unless it was a passive, but if so - what would the second Advanced Item be? A Pickaxe, maybe? That could work, but then it'd be a lot like Zephyr. It's a good concept though.
