Its a pretty simple S3 Darius guide (but it also has the strongest BUILD on the site hands down :<). I didn't really want to make a match-up section as a lot of match-ups for darius are pretty straightforward, but I'll probably make one when I get the time, I have this bad habit of typing way too much in match-up sections though :<.

(Maybe I'll narrate it instead :O)

EDIT 2:
Re-released it with a fixed cheat sheet and some added info, wasn't aware it was so overwhelming to people. Thanks to tehasian and OTGbionicarm for the initial feedback, wish I could let people preview guides without publishing them. (HINT HINT)
