tokill and joka are noobs, don't worry about them.

ya they are reroll from baal charms and duped, you CAN still reroll them, but it's going to long ass time, I reroll baal sc at ladder, the best I could get is small 175 psn damage over 6 second. I rerolled 5 of them, and took me long ass time.

I wouldn't suggest you rerolling those charms because the time you spend on them would be worth more than what you paying for a dupe one.
