Hello, i am a new to the server. Have been palying for some weeks and i am using https://l2db.club/index.php as a database for drops, recipes etc. Since now it has been 100% correct on the mob drops but for 5 days i have been killing Breka Orc Perfects for the mithril alloy recipe, which is 1/200 drop. As propabilities go that not possible since i have killed more than 1000 mobs, possible to be around 2000. The second question is generally to the database itself, if it is accurate on other drops too, or if there is a better one we can all use.
