Rare Drops! What is known?

Alright, So lets sort this out. At this time there are 4 rare drops known. these are: Dark Fang Shield, Magikat Hat, Quicksilver Helm, and Quicksilver Mail
so lets find out which have been seen or not....
If you have seen any of these 4 rare drops on a player, please screenshot it and post it here. That way we can properly track each of the rare drops so we know which are confirmed to be in the game, and which are still a mystery. Also if you can report where it was found that would be awesome :D
Before it was added to Brinks, the only known Blackened Crest was found in a box in Tier 2.

I know it wasn't the ONLY... Saw a few peeps going around with CoA and BCs
Magikat Hat has been seen, but not since release.

GMs had the Crest of Almire before it was available (And it's still part of their default loadout). Additionally, the Aegis strongly resembles it. It's possible you saw those.

Nope. I've seen CoA's before! Blackish with the cloth thing like the aegis.
Yeah, but until this guy, you only saw it on GMs.

Speculation: These ALL - not positive on magikat hat - drop from treasure chests currently. They are implemented in the game, but have not been made readily available. Similar to how Blackened became a token item.
I think these will be put into place as either rare drops or token items.
I can see the gremlin shield becoming a new token shield for the upcoming boss.
Quick silver possibly for jelly tokens with the changes coming to tokens but more than likely that and kat hats will be released eventually as rare drops off monsters along with possibly a list of new rare gear to follow.
Only the Magikat hat has not been seen. The other three have been documented. Screenshots were posted ages ago and farmed for stats images and icon colors for the wiki.
