From what I can see there are lots of characters missing in the compendium.
From my own inventory I can see that these are missing in

Hogmanay Eddie
Storm-Rider Killers Eddie
Storm-Rider Reaper Eddie

Brian Kek, CEO
Dark Advent Angel
Dark Advent Lucifer
Guotin, 天兽
Krampus (Magus)
Mercenary Vanguard (Sentinel)
Mercenary Vanguard (Warrior)
Santa Claws And Comet
The Storm-Herald

There might be additional characters missing that I don't have.

Isn't compendium meant to be the official documentation for characters, talis etc?
