Needs another drop. 1.4 keys = 1 key + 3 ref 1.5 keys = 1 key + 4 ref

Not very many people selling for around 1.8 keys, plenty sellers at 2 keys though. Very easy to get for 1.4 or 1.5 keys anyways.

Unsold for around 1.8 keys (around 1 key + 6 ref I'm estimating):

Unsold for 2 keys: Since these are out of the range I don't feel it's really necessary to label them
