 This started out as part of section 2, but I realized it was a *large*, open topic. The larger roguelike games, such as Dungeon Crawl Stone Soup, Cogmind, Caves of Qud, etc. all have a variety of maps. Section 3 is all about map building, and will cover many of the available algorithms for procedurally building interesting maps.

 Every year, the fine fellows over at [r/roguelikedev](https://www.reddit.com/r/roguelikedev/new/) run a *Tutorial Tuesday* series - encouraging new programmers to join the ranks of roguelike developers. Most languages end up being represented, and this year (2019) I decided that I'd use it as an excuse to learn Rust. I didn't really want to use `libtcod`, the default engine - so I created my own, [RLTK](https://github.com/thebracket/bracket-lib). My initial entry into the series isn't very good, but I learned a lot from it - you can find it [here](https://github.com/thebracket/rustyroguelike), if you are curious.

 This tutorial is primarily about learning to make roguelikes (and by extension other games), but it should also help you get used to Rust and RLTK - The *Roguelike Tool Kit* we'll be using to provide input/output. Even if you don't want to use Rust, my hope is that you can benefit from the structure, ideas and general game development advice.

 In the last chapter, we added items and inventory - and a single item type, a health potion. Now we'll add a second item type: *a scroll of magic missile*, that lets you zap an entity at range.

 In the last few chapters, we've focused on getting a playable (if not massively fun) game going. You can run around, slay monsters, and make use of various items. That's a great start! Most games let you stop playing, and come back later to continue. Fortunately, Rust (and associated libraries) makes it relatively easy.

 We have all the basics of a dungeon crawler now, but only having a single level is a big limitation! This chapter will introduce depth, with a new dungeon being spawned on each level down. We'll track the player's depth, and encourage ever-deeper exploration. What could possibly go wrong for the player?

 Currently, you can advance through multiple dungeon levels - but they all have the same spawns. There's no ramp-up of difficulty as you advance, and no easy-mode to get you through the beginning. This chapter aims to change that.

 Now that we have a dungeon with increasing difficulty, it's time to start giving the player some ways to improve their performance! In this chapter, we'll start with the most basic of human tasks: equipping a weapon and shield.
