Yeah. Or enchanting your circlet at 10% and seriously ticking everyone off!Unless you are an infuser. Most pointless gambling craft in the universe (I am considering what goes in, not just what comes out!). "YES success at 20%! I get ... eh."
Statistically speaking, forty attempts is actually a small sample.
Do remember you have a 25% chance each attempt. It is no guarantee you will successfully craft 25% of what you attempt to make.
But it is a lot of CNR.
