Bumpity~ someone please check it.

-Make the duration 6

-Change the diameter to 10 m

-Speed buffs have a specific speed, I believe it's stated in the 4th post or so in the magic section.

-Take out the using physical attacks, it kind of gives a bit of a double effect to it. You could use magical physical attacks though, like shadow surrounded fists or whatever.

-Pick a place where it must be fired from like a limb or your chest/back and give the explosion a size.

-The endurance debuffs are in the post below the buffs, it just needs a tad bit of editing to the wording is all, you can pretty much copy/paste the description in the rules.

-Take out that it takes .2 seconds to reach the height, that would imply it moves faster than it does.

Edited, sire. Now check it again~
