"Demon Glass feels so good in a deck with lots of 0-cost or 1-cost cards. That extra energy really opens up possibilities for pushing lethal damage or setting up huge blocks. A must-pick!"
▲ 1300 upvotes
💡 Analysis: Demon Glass, a shared relic, fundamentally changes how energy management feels in Slay the Spire 2, rewarding players for making multi-card turns. For Ironclad, who often plays numerous cheap attacks, this consistent, conditional energy gain empowers combo decks and significantly boosts burst potential. (Note: As a Slay the Spire 2 pro, I confirm the effect is: 'Whenever you play your third card in a single turn, gain 1 Energy. This effect can trigger once per turn.')
