Some of the rifts were even valuable, dropping a variety of rare skills. The rifts were marked as keep-able, but their primary purpose was to test terrain and other factors.
The two of them then repeated their testing with rifts near the same areas, and with the outside world cut off. In those rifts, the terrains more closely resembled the areas around them, but interestingly enough, they had far less variation in skill drops.
The rifts still followed the standard twenty-five percent rule for skill drops, with there always being three common skills that dropped seventy-five percent of the time. There was also one rarer skill dropping just twenty percent of the time, called the uncommon skill. The remaining five percent chance for a skill was utterly random, but could even ignore Tier bar
