Gem chest drop table?

I am just wondering if its got a weird droplist like the event chest has or if I can actually get every ultra rare and above for it any time? It says chest contents change after xx days so I’m guessing its just a weird table and not full availability. I have never used it before and made enough stupid mistakes recently so dont want another one my hands, ta!

I get to use this again!

Troops released in weekly events aren’t available in chests for 4 weeks, so that’s why it says that the chest contents will change. Otherwise, you’re correct: gem chests contain any available ultra-rare or better troops, and any runic or arcane traitstones.

And possibly celestial traitstones
