What does soft, sharp and hard cap mean on the wiki

Soft cap is the point where you begin to get less and less out of a stat you put a level in. Hard cap is where it downright becomes absolutely minimal, and isn't very useful to continue putting points into after that point. 40 is the soft and 60 is the hard cap for several stats.
Vitality and Luck don't really have these caps; they remain consistent in giving you equip load and item discovery, respectively, all the way up to 99

Things like Vigor, you barely get any more health per point past 40. In fact I think the difference in health you get from 40 to 99 is like 100 extra HP, while obviously you get over 1000 from 1 to 40 Vigor.

Soft means where you get less for each point into the stat, sharp is where you get even less, and hard is where you barely get anything.
For example: End: You get about 1 END every 5 or so LvLs after 40 end.
