a lot of people like to pull out dung pies and/or poison knives/arrows when they see dragons. with this setup they're a lot less annoying (you have more poison resist than the most standard pvp armors). pike is lightning for the chip damage and should be decent at breaking guard w dragon roar. dex is 13 so you can swap it for furysword if you'd like (roar doesn't combo into pike r1)
