well, the custom doesn't "count" toward the tree points.
they are considered equipment. by that, i mean that those points won't show up when you assign skill points.
so your tree should look like 00000 when you try to assign them, right?
if you want to build pancake, shit...
now i'm confused!
so you can put a point into get low???
if so, then put a point into get low, hands, and cut block.
you should then be able to put the remaining two into pancake and your tree will look like this: 12222 (with the equipment)
either way, you have to build up previous skills to get the next one maxxed out.
i'm still confused because when i added my custom i already had points in run block and hands. but the main thing is this...
if it says prerequisite level not met, add points into the skill ahead of it.
my head hurts!
good luck
