*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.
*For skills below 10, you can dig slopes up to 30.
*It is not possible to dig on [[cliff]] or [[rock tile]]s. Rock tiles can be [[Mining#Surface_mining|mined]] down.
