First off, I'd like to thank Baloo ( Crown King ) and Mr. Bucket for helping me out with my first suggestion, giving me advice and such. Please, correct me if any of this seems wrong. Yes, I own one.

Currently only 2 in existence, the other is gifted. Hasn't been on sale since.

I paid a Haunted Ghosts Conjurer's Cowl and 15 keys for this hat.

The Cowl's mid range is - 4.2. 4.2*0.9=3.8.

Key range - 15/21=0.7.

New Price - 0.7+3.8= 4.5

Here is my proof.

Overall, I paid more than what the current range is and due to being the only sale in 3 months, I feel this hat deserves a small bump.
