Hey, thanks for all the great feedback. Much appreciated.
The skeleton lich is absolutely not balanced. I put it on a really low chance to pop up as something of a secret elite enemy that shows off some experimental mechanics. Even then, I should probably take it out until the whole thing becomes a bit less frustrating. Putting the ritual in hand, rather than in-deck would probably work to that end.
And apologies about the apparent inventory bug. There's ~1-2 bugs that I know about but that have proved difficult to test for in regular play. Mana-pool inconsistency and a rare inventory slot bug are on the list, but I still haven't completely narrowed down yet. I'll get them sooner or later, but they haven't come up in play too often yet. Thanks for highlighting the issue though.
Glad you enjoyed the current build. Stay tuned, I'll get things shaped up.
