*'''Note that the material is dug from the corners of tiles; Where your avatar's feet are (which of the four corners in the tile you stand in) is where the tile will be dug down. Where you right-click to select the dig command has absolutely no impact whatsoever on where you dig.''' So, for example, by standing in the northwestern corner of a tile and digging, just that area of the tile and connecting tiles will drop. The other three corners of the tile will remain at their original level. By then hovering the cursor over neighboring tile borders, one can then see the results of their work via slope count (1 slope = 1 dirt = 1 dig action). Dropping dirt on tile corners works the same way but by raising the corner in which the player is standing when dropping the dirt.
*The maximum slope you can dig on, level, or flatten is 3 x [your digging skill]+ 1. e.g. A skill of 50.25 in digging will mean you can dig on, or adjacent to, a slope of up to 151 dirt.
*It is not possible to dig on [[cliff]] or [[rock tile]]s. Rock tiles can be [[Mining#Surface_mining|mined]] down.
