I am currently working on other projects and not actively maintaining this mod. 1.9 might get me to revisit it once the modding support is there - it implements many of the changes that I would have (or did) myself, and the new features such as cooldowns, special arrows, and dual wielding open new opportunities. (Consider, for example, a sword that has a secondary right-click spellcast ability, but only if your off-hand is empty.)
The Azure Cloak is used for flying, in conjunction with a Sky Lens installed in a starwell. It works very much like the new wings in 1.9 do.
