Enchantments are permanent, irreversible card modifiers. This guide covers every confirmed Enchantment type, the selection principles that top players agree on, and build examples that use Enchantments as a win condition.
The Symbiote event presents Enchantment choices — the core decision this guide covers.
Enchantments are one of the most misunderstood systems in Slay the Spire 2. New players treat them as free upgrades. Experienced players know they are double-edged bets that can carry a run or quietly destroy it.
Every Enchantment modifies a card for the rest of the run. That permanence is the entire point: a good Enchantment on the right card at the right time is transformative, but a bad Enchantment on the wrong card is a permanent tax you pay every combat.

Fast takeaway
This guide is built around one practical question, so you can use it during a run instead of digging through a broad overview.

Corrupted Enchantment adds 50% attack damage but costs 3 HP every time you play the card. It is strongest on high-damage finishers you play once or twice per combat (, ) and weakest on high-frequency cards like Shivs where the HP drain compounds fast.
Spirit Enchantment turns an Exhaust card into a Strength generator. The Chinese community calls this the most explosive Ironclad build in early access: a 0-cost card with Spirit Enchantment gains +2 Strength per play, and + + let you cycle it every turn for free.
Vulnerability Enchantment adds Vulnerable application to an attack at the cost of increased energy. It is best on opening-turn attacks in Strength builds because Vulnerable multiplies all subsequent hits in the same combat.
Corrupted: +50% damage, −3 HP per play. Best on finishers, deadly on spam cards.
Spirit: Exhaust → Strength generation. Core of the Ironclad 灵体附魔流 build.
Vulnerability: adds Vulnerable, costs extra energy. Best on turn-1 openers.
These principles are consistent across English, Chinese, and Japanese community guides. They hold regardless of which specific Enchantment you are evaluating.
Match your build direction — Enchant cards that align with what your deck already does. A Corrupted Enchantment on a card your Strength build barely plays is wasted.
Never blind-enchant — Read the full trade-off. Enchantments are not free upgrades. The cost side matters as much as the benefit side.
Avoid HP-drain on high-frequency cards — Corrupted on a card you play 5 times per combat is 15 HP per fight. That kills runs.
Consider combat duration — Short fights make HP costs tolerable. Long boss fights make them lethal. Enchant accordingly.
Commit only when ready — Enchantments are irreversible. If your build direction is unclear, skip the Enchantment event and come back stronger.
This is the highest-profile Enchantment build in the Chinese community. The core is a 0-cost Exhaust card with Spirit Enchantment that generates +2 Strength every time it is played. makes all Skills cost 0 energy but Exhaust after use. draws a card whenever you Exhaust. gives Block whenever you Exhaust.
The result is a free Strength engine: every turn, cycle through your Skills at 0 cost, gain Strength, draw cards, and gain Block. Finish with (Block → damage) or (0 cost, 17 AoE damage).
The build requires three specific cards (, , ) plus the Spirit Enchantment. That makes it a high-ceiling, medium-consistency strategy: devastating when assembled, but dependent on finding the right pieces.
The simpler Enchantment build: put Corrupted on your primary finisher ( or a multi-hit attack) and scale Strength with plus current-card-pool support like and . At 20+ Strength, the 3 HP cost per play is irrelevant because the fight ends in one or two swings.
The key rule is to Enchant only your finisher card, never your cycling or support cards. A Corrupted costs 3 HP every time you draw through your deck, which adds up across a long run.
No. Enchantments are permanent and irreversible for the entire run. This is confirmed by Mega Crit's official Neowsletter and verified in early-access play.
Are Enchantments always worth taking?
No. Enchantments are trade-offs. A bad Enchantment on the wrong card is a permanent downgrade. Skip the event if your build direction is unclear or if the offered Enchantment does not match your deck.
Which Enchantment is best for beginners?
Vulnerability Enchantment on a turn-1 attack is the safest choice because it amplifies all subsequent damage without a recurring HP cost. Corrupted is high-risk, high-reward. Spirit requires a specific Exhaust shell to function.
Does the Spirit Enchantment build work on characters other than Ironclad?
Necrobinder also has Exhaust synergies and can use Spirit Enchantment effectively. Silent and Regent lack the Exhaust infrastructure to make it consistent.
