Great job. I just have one small critique and then a question.
My critique is that I'd link your skill calculator right above the video explaining it. Not a major thing but it could save those looking to use it a bit of time.
My question is I'm a content creator myself and I'd like to create a skill calculator for a different game I've made content for (I won't do one here because I don't want to compete with the hard work you've already done!) Did you custom program this entire calculator or do you have some kind of skill tree builder plugin I might be able to use? I've been looking for a good skill tree plugin for WordPress and haven't found one.
