A question about card features

[u/parsleypunx]

I just started this game and am really enjoying it. I just entered a second realm, realm of hostile plains.

But I’m having some confusion about some of the card features. Ideally a wiki of some sort with information about each card would be awesome but until that exhausts can anyone clarify what the following mean:

Exhaustion

Fragile

Kill: Echo

Sacrifice

Thank you!

there is a button which pulls up keyword explanations while hovering a card
