>>34127377I think the spaces available through the holes are shuffled once in a while.
I originally found nihilego in a one-rigned hole, celesteela in a two-ringed one, and pheromose in a normal hole, now I can't find any Nihilego, normal holes still lead to Phero, one-ringed holes lead to xurkitree, two rings to celesteela.
I found a two-ringed with the fan effect that's used for legendaries but there was a regular celesteela inside. Still haven't found Guzzlord.
