Ice Climber is a level 60 item. Is it limited to level 60 or does it also drop as a level 70 version? I found already three or four Fire Walkers but not Ice Climber at all. Fire Walker was originally a level 50 item but drops also as level 70 item. I am wondering if it is the same with Ice Climber? Does anybody have a level 70 Ice Climber?
Ice Climbers are not limited to level 60, they can and will drop at higher levels too. the level you can see on the battle.net website is the minimum level they can drop on.
So every single non-crafted legendary can drop at level 70. The fact that you got multiple Fire Walkers and no Ice Climbers is just based on luck (on a random number generator actually, but that resulst basically in luck).
As proof: At the time of this post this character is wearing lvl 70 Ice Climbers. Or just look at the screenshot I found of them
