This datapack adds the Unstable origin to the origins mod. This requires the fabric mod loader version 1.17, and the 1.17 version of the origins mod and fabric API.

Powers:
When exposed to the sky, you can get randomly sent to the nether
When not exposed to the sky, an ability bar fills up. While it is filling up, every entity gains effects such as slowness, speed, jump boost, resistance, wither, hunger, and levitation. When it is filled up, the next entity you punch gets sent to the end
You have eight hearts
The secondary key launches you forward
You can phase through blocks(togglable with primary key)
You are transparent, and your skin has a red tint
You can't wear armor heavier than chainmail

Thanks to Mr Baguette for the suggestion
