Well, wall-climbing alone seems pretty shallow. But if you add some quirks to the armor to make it like a mobility-enhancing set, it would be quite the fun armor. Something such as making the armor allow you double/triple jump, move at fast speeds, have some sort of tabi effect or maybe even have a black belt effect to it. I feel like the ninja armor should had been something like this instead of throwing armor that is outclassed by fossil very easily. Agility is something that isn't very worked into the game, as most people tend to tank enemies or spam lifesteal.I'll give it some thought. I dunno how well a wall-climbing armor set would work, given there's already a way to climb walls with an accessory.
