I've done the Canith challenges and they can be quite challenging but not impossible but the Evensingstar especially the Defenseless challenge, to be almost impossible to get completed in the time constraint for the challenge, and for items with unsure abilities except for the cloaks. Plus I heard that the Dyrad challenges were easier before they changed them, but again to do these challenges for unknown item abilities make them not worth trying even though you can turn the item back in for about half the tokens you paid for item. Give us a good reason to do the challenge other then pot luck and hope I'll like the item abilities. PS Everything in the challenges is bound to character unlike the Canith challenges that are bound to account.
