Slay The Spire 2 Eidolon Guide
Eidolon is one of the more unusual cards available to the Necrobinder in Slay the Spire 2. Instead of dealing damage or providing block, the card focuses entirely on exhausting cards from your hand to trigger a powerful defensive effect.
Because of how the mechanic works, Eidolon is usually only effective in very specific deck setups. When used correctly though, it can provide one of the strongest defensive buffs available.
What Eidolon Does In Slay The Spire 2
Eidolon exhausts your entire hand, and if at least 9 cards are exhausted this way, you gain 1 Intangible.
Intangible is a very strong defensive effect. While it is active, all damage you take is reduced to 1 for that turn.
Because Eidolon exhausts your entire hand first, the card requires careful setup before it becomes useful.

How To Trigger Eidolon
The main challenge with Eidolon is exhausting enough cards. The effect only activates if at least 9 cards are exhausted.
This means you usually need a very large hand or a deck built around generating additional cards before playing Eidolon.
Cards that add extra cards to your hand or draw multiple cards can help reach the requirement more consistently.
When Eidolon Is Most Useful
Eidolon works best in decks that already focus on exhausting cards. If your deck regularly fills your hand with extra cards, it becomes much easier to activate the Intangible effect.
It can be especially helpful against enemies that deal large bursts of damage. Triggering Intangible right before a big attack can prevent most of that damage.
Without enough cards in hand though, Eidolon will simply exhaust everything without granting the Intangible effect.
Final Blurb
Eidolon is a rare Necrobinder skill in Slay the Spire 2 that exhausts your entire hand in exchange for a chance to gain Intangible. The card requires exhausting at least 9 cards to trigger its effect, which means it works best in decks that generate large hands.
When the requirement is met, the defensive value of Intangible can completely shut down heavy enemy attacks.
