So Digital Gloomhaven has a nice little wrinkle for Spellweaver, as I learned tonight: If you burn Reviving Ether without playing the card (say, for example, if you lose it during a Short Rest) you can get it back from cards that recover Lost Cards, like the Tinkerer's Stamina Booster.

This is a pretty big buff for Twin Restoration, since now you can guarantee that you'll be able to use Twin Restoration either pre- or post-Ether. Also, I guess this gives you flexibility when short resting, since you can get back Ether with Twin Restoration if your short rest accidentally hits Ether.

How good does Twin Restoration become with this change? Probably worth picking up at level 7?
