Chai Stones: Daily Calendar +ARP (+1 to 6 based on upgrade lvl). For more info click left on "AWA Information", there is a thread called "Artifacts Info" with all of them listed.

these seems like one of the must-have artifacts, do more experienced people agree I should try to buy it?

It depends on how much time you got for your daily tasks & how reliable you are. This one is super quick, reload the page a day & collect the extra ARP.

Everyone should be buying this one if they don't have it. It can add up to 3 bonuses a day: bonus ARP to the daily calendar ARP, bonus to the 7 day login ARP, and when a promo gives daily ARP it can add an ARP bonus to that too.

Sometimes you'll only get 1 (if the calendar login gives a cosmetic or fragments then), but most of the time you'll get 2, and on those rare promo occasions (a little more rare in regions where we get DRP vs ARP), 3 bonuses is pretty sweet.

@easyrhino yes its one of the must have's.

Its a must have in my eyes, worth like 4380 ARP a year once upgraded to max.

Its also part of 15% marketplace discount set (which works on game vault too).

@MysteriousMrX @MysteriousMrX ok thanks guys. I am also saving up for as many DRP as possible before black friday. When do the DRP in marketplace reset? I got one in september and it shows claimed without a fresh one.

@easyrhino - 4 times per year, so next DRP reset should be around start of November.
