Re: weirdness of skillchains elements in SCH Macro screenshot, confusing at first, detonation -> compression makes gravitation, gravitation -> distortion makes darkness, Reverbaration -> Impaction makes Impaction, so if it's in a paired box it makes higher level chain basically.
My brain hurts just looking at this skillchain rainbow. Im glad there are people who are able to read and understand skillchain charts, and many props to them.
Never really understood the use of charts like this. The way it's laid out in a list format on http://ffxiclopedia.wikia.com/wiki/Category:Skillchains was my go to for years. A lot easier to read.
