[quote=@TheUnknowable] It partially answers my question. Say my dad was taught by his father to Earth Wield, and has been practicing several days per week since he was Ten. Would it be believable for him to create a 100x.5 meter cylindrical well in less than a day at the age of Forty, with breaks every time he wears himself out? How large of a cylinder of stone could my character, say a twenty-five year old that has been practicing almost every day since he was ten, lift at once? Would it be conceivable for him to create an identical well in a day (10-12 hours max work). What I'm essentially trying to get at is what qualifies as OP? [/quote] 100 meters of rock would be OP even with 30 years of experience. At most, 10 meters would would be the limit for a man of his age and experience, anything more would be a bit if a stretch. So with 10 years of experience 8 to 9 meters would be reasonable. Could you imagine throwing 300 feet of solid rock at someone! 0.0
