I feel like shrine vessels could be heavily improved. What about a single vessel for all the shrines with shrine points for each of them (similar to how stockers used to work in eastern sun, if anyone played that mod). Cube to select output (cycle through all shrine types) and cube with a key to extract a shrine.
Besides the vast space that all shrine vessels occupy, this would also solve the problem that you always need 1 point left in a shrine vessel for it to remain a shrine vessel, which feels really bad since you can't access the last shrine without breaking the vessel.
