He seems to be writing that when it comes to drops that are mostly in very hard with one ultimate drop. How often hit and high %s drop is affected by a lot of things, difficulty, area, monster, even section id seems to play a role sometimes. If it has a good chance of dropping with good stats, that includes all the stats, not just hit. The way I used to hunt DoB was to spam ep 2 max attack 2 hildeblue on whitill, i would find a ton of them and every other run or so one may have 45 hit on it. It may only be very hard, but the sheer volume of DoB I would find doing it made finding good ones happen often. I never found 50 hit though. I've not had as much success getting high %s on other hildeblue drops on other ids, which is why i said id may play a role too. Without looking at the game fiiles, it's hard to quantify how often the high quality stuff will drop from areas/monsters/etc, but just in general higher level areas/monsters drops better gear more often. Shambertin PoD boxes have dropped me 55 hit gear on tons of runs xD.
