Umbrella（傘）

I'd like to see umbrellas added. The purpose would be to allow for a slower, safer fall. However, I think it might not disrupt the game balance if there were elements like being unable to use both hands while falling. Also, I thought it would be great if we could customize the umbrella's pattern using a loom. I think the umbrella could be made using four Phantom membranes and three sticks.
