How long does it take for battle stats to reset? As in the number of times you've battled an opponent? I noticed that after I battle an opponent 10 times I don't get any more exp, but after a period of time it resets back to battling the 1st time and so I can get exp again until I get to 10 battles. I wonder how long this reset wait is? I never kept track of it. Is it every couple months or once a year?

the resets aren't something that it's done regularly. they happen when there's a major change on the coliseum. so next time can be tomorrow or in five years. there isn't a way to know.

i just hope it happens soon haha :'D

Aww darn I wish it was more regular so it would be easier for higher tiered pets to level. Oh well. Thanks!

Although a full scale reset doesn't happen unless a major change happens, individual challengers do reset if there is a change in their loot. The Morostide challengers and the Fireside Cursed Effigy reset every year.

EXP can still be racked up through battle quests though, where any opponent you do not have to unlock can show up and they reward anywhere between half to full of their listed EXP.

Like MrCool said, battling through BQs advances a pet exponentially, as well as event battling that happens every so often and annual challengers like the Morostide, Fireside and Anniversary challengers.

If I'm not mistaken the last reset was in 2012 with the addition of tiers. So it's been almost two years :)
