For my D&D game, what dice, mat, and accessories do I use?

So, the first video I made was talking about how you don't really need anything to get started playing D&D. The next live video here is talking about how that video is DEAD WRONG and how you should totally go out and buy a bunch of cool stuff for it! People are curious about the stuff I have so: the box with the minis is called "Pathfinder NPC Codex" the large dice are called: "jumbo d20 Chessex"
