floor(value) rounds down value. So floor(6.5) = 6.
exptnl(level-1) is just the amount for the previous level. It's technically a recursion and not an exponential, because of that floor in it. But either way it doesn't make a mind-blowing difference.
Cyanne, will do - at least I'll move it to the top of its spoiler, I'm a bit hesitant to move it in with the weapon formulae because there's already staff/wand whack and technically it's a skill-related formula. It just happens to be used for a bunch of them.
