Hello. I went in search for a place where I could find tutorials of how to make encounter maps for tactics games, this means a small scale location with a grid (I was lead to this site). I wanted to have specific terrains in mind, being lava, ice, snow, grass, dirt, water, rivers depicted in motion, as well as a few props like boulders, buttons, tap boxes, fountains, and also a bunch of other things.

What kind of map tutorial would allow me to draw that sort of stuff without having to spend years honing the fine details in?

If you want to know what kind of game it's for a Pokemon Conquest Role Play. (I've already got the global map created.)
