Description
While having Jump boost you're ascent will slow down (and stop) after releasing the jump key, allowing you to have better air control. AKA it won't make you rocket into the sky, you won't fail a jump because you're head hit the celing.
Higher level of jump boost will be better to have.
Will work fine under "normal" levels of jump boost (up to 4). After that, the stop will be too sudden, and there isn't really much to do about it. (whitout rewriting the effect entirely)
At the moment there is a bug, That it will crash your server. It'll be one of those things I'll get to (sorry for the inconvinience).
