I don't have an issue with the 62 points of damage portion. It's a niche effect, meaning that it'll be extremely effective in some situations, and nearly useless in others.
Putting a new character out of a bunch of gold right off the bat for a 3rd level spell does seem a bit harsh, but I think it's also necessary to make Blacksmithing more viable as a production skill.
62 points is an outlier I agree, but given the new layering rules and increased armor values I think it's safe to say that the vast majority of players are going to be at their class maximum which means that shatter will do a minimum of 15 points of damage, 25-35 points against fighter types, and in some niche circumstances up to 62 points. Combined with the fact that if your armor is not rendered you cannot "heal" that amount back until you visit a blacksmith and buy a new suit of armor, it still seems far too powerful for a 3rd level spell.
