Bear in mind that Boss Jewels were not originally a part of C3, they’re a custom implementation. I’ve checked the stats and the jewels should give a standard amount plus a small percentage.
well they do 100 dmg the percentage is not working. its actually not fealable 😀 and if you implemanted s grade sets already why not give the real stats to the jew. since i mean you have s grade in there already, i can understand the setting if there is no sgrade tho. but the settings are bad if you have sgrade in there. since this is not even a part of c3 at all 🙂 so imho you should fix up the jew.
