How solid is a Ghostchi
Ghostchi is quite solid, only translucent enough to see through but enough to touch, their body holds weight in the world. They are more solid than they were when they died though. when they first died, they were completely corporeal. They sunk down the floor in their sleep. They did not wake up for a long while, years. But when they did they were still light enough to phase through walls, although it was slightly more uncomfortable. This is how they got out of the bunker for the first time.
Over time they have become much more solid, more human, and able to "die" and reset, respawn. They gained the ability to walk on the ground (slowly also losing the ability to fly), they once again knew what it felt like to be hungry. They became more un-solid, and thus unable to survive suffocation. The first truly player trait they gained back, was the ability to destroy blocks.
