Versatility: ★4.5 Synergy: ★5.0 Act 1: ★4.0 Act 2: ★5.0 Act 3: ★5.0

REDDIT META WATCH

"WHOA, Demon Tongue sounds wild! Imagine playing Combust and just... not losing health? Or Blood for Blood for free? This relic could totally redefine how we use HP as a resource. HUGE potential, easily a run-maker!"

▲ 950 upvotes

💡 Analysis: Demon Tongue provides an unparalleled form of HP insurance, effectively negating the first instance of HP loss each turn, turning HP costs into free actions.

Versatility: ★4.0 Synergy: ★5.0 Act 1: ★4.0 Act 2: ★5.0 Act 3: ★5.0

REDDIT META WATCH

"Okay, Paper Phrog just makes Vulnerable feel *broken*. Your Bash+ just got a HUGE upgrade, and if you have Shockwave or Thunderclap? Forget about it. Bosses just melt into a puddle. Absolute S-tier relic for Ironclad, no cap."

▲ 900 upvotes

💡 Analysis: Paper Phrog dramatically amplifies the effectiveness of Vulnerable, making Ironclad's inherent debuff application a central pillar of damage scaling. This relic allows for devastating burst turns, turning even minor Vulnerable sources into significant damage multipliers that shred through high-health enemies and bosses.

REDDIT META WATCH

"Okay, Ruined Helmet just rocket-launched Strength builds into orbit. A single Flex is +4 Str, a Spot Weakness is +4... and Limit Break? OH MY GOD. This is a must-pick for any strength-scaling Ironclad. Absolutely busted and feels amazing!"

▲ 1000 upvotes

💡 Analysis: Ruined Helmet offers an explosive early-combat Strength spike, effectively doubling the impact of Ironclad's initial Strength-gaining abilities. This relic accelerates scaling dramatically, turning even a basic Flex or Spot Weakness into a significant power boost that can quickly snowball encounters and melt formidable foes.

Versatility: ★4.5 Synergy: ★4.0 Act 1: ★4.5 Act 2: ★5.0 Act 3: ★5.0

REDDIT META WATCH

"Okay, Demon Glass sounds absolutely insane! A free attack every turn, especially if it's a high-cost one like Bludgeon or Sword Boomerang? Plus it exhausts for Charon's Ashes synergy? This is a boss relic dream for tempo and deck thinning! Please tell me this is real!"

▲ 1100 upvotes

💡 Analysis: Demon Glass provides unparalleled early-combat tempo, offering a free, Exhausted Attack card every turn, ensuring consistent energy efficiency and damage. This relic significantly accelerates Ironclad's ability to clear rooms and thin the deck, allowing for more aggressive plays and quicker access to key combo pieces, defining a fast-paced, high-impact meta.

Whenever you lose HP in combat, gain 3 Block next turn. Ironclad Ironclad

Versatility: ★4.0 Synergy: ★4.5 Act 1: ★4.0 Act 2: ★4.5 Act 3: ★4.5

REDDIT META WATCH

"Self-Forming Clay is low-key one of Ironclad's best defensive relics. If you're running any HP-cost cards like Combust or just taking hits, that consistent block generation adds up to SO much mitigation. Love it for sustain and enabling spicy plays!"

▲ 700 upvotes

💡 Analysis: Self-Forming Clay is an exceptional defensive relic for Ironclad, passively generating Block whenever HP is lost, whether intentional or not. This synergistic effect makes HP-costing cards significantly safer and more rewarding, providing consistent damage mitigation that scales with Ironclad's aggressive playstyle.

#6

Charon's Ashes Relic

Whenever you Exhaust a card, deal 3 damage to ALL enemies. Ironclad Ironclad

Versatility: ★3.5 Synergy: ★5.0 Act 1: ★3.0 Act 2: ★4.5 Act 3: ★5.0

REDDIT META WATCH

"Charon's Ashes + any exhaust deck = pure destruction. Seriously, if you're building around cards like Sever Soul or True Grit, this thing just melts multis. It's so satisfying to watch everything just take damage for cleaning up your deck. SO GOOD."

▲ 850 upvotes

💡 Analysis: Charon's Ashes elevates Ironclad's Exhaust archetype by transforming every exhausted card into a source of valuable AoE damage. This relic is a game-changer for builds focused on deck thinning and cycling, providing consistent offensive pressure while simultaneously improving deck efficiency, making elites and multi-enemy encounters trivial.

Black Blood Relic

At the end of combat, heal 12 HP. Ironclad

Versatility: ★4.5 Synergy: ★3.0 Act 1: ★4.5 Act 2: ★4.0 Act 3: ★4.0

REDDIT META WATCH

"Black Blood is just straight up a better Burning Blood, and that consistent healing makes such a huge difference, especially in longer runs or when you're pushing for elites. Definitely a top-tier boss swap if you can get it, never regret seeing this!"

▲ 750 upvotes

💡 Analysis: Black Blood is a foundational upgrade for Ironclad, significantly boosting the character's inherent sustain by doubling the healing from the starting relic. This consistent HP recovery empowers more aggressive pathing and risk-taking, effectively expanding Ironclad's HP pool as a long-term resource across the entire run.

Brimstone Relic

At the start of your turn, gain 2 Strength and ALL enemies gain 1 Strength. Ironclad Ironclad

Versatility: ★2.5 Synergy: ★4.5 Act 1: ★3.0 Act 2: ★4.0 Act 3: ★4.5

REDDIT META WATCH

"Brimstone is that relic where you either die a horrible death or become an unstoppable god. The STR gain is insane, but you absolutely NEED to be killing things fast or have some insane block generation. No half measures with Brimstone, it's all or nothing!"

▲ 800 upvotes

💡 Analysis: Brimstone is a high-risk, high-reward boss relic that offers unmatched Strength scaling for Ironclad, allowing for ludicrous damage output every turn. However, its significant drawback of enemies also gaining Strength demands either overwhelming offense to end fights quickly or exceptionally robust defensive strategies to mitigate the rapidly escalating incoming damage.

#9

Red Skull Relic

While your HP is at or below 50%, you have 3 additional Strength. Ironclad Ironclad

Versatility: ★3.0 Synergy: ★4.0 Act 1: ★3.0 Act 2: ★4.0 Act 3: ★4.0

REDDIT META WATCH

"Red Skull is SO underrated. Pair this with a few good damage cards or even just Whirlwind and suddenly being at 40% health feels like a power move, not a death sentence. Embrace the low HP life, unleash the fury!"

▲ 600 upvotes

💡 Analysis: Red Skull offers a powerful conditional Strength boost, transforming low HP into an offensive advantage for Ironclad. This relic encourages a high-risk, high-reward playstyle, making 'bloody' builds exceptionally potent by turning critical health states into opportunities for massive damage spikes.

#10

Burning Blood Relic

At the end of combat, heal 6 HP. Ironclad Ironclad

Versatility: ★4.0 Synergy: ★2.5 Act 1: ★4.0 Act 2: ★3.0 Act 3: ★3.0

REDDIT META WATCH

"Never underestimate the power of Burning Blood. It might feel small later on, but those 6 HP after every fight add up HUGE, especially in Act 1. It's the silent MVP keeping our runs alive and kicking, letting us push for more elites!"

▲ 400 upvotes

💡 Analysis: As Ironclad's starting relic, Burning Blood establishes the character's identity around sustain and endurance, providing crucial passive healing after every combat. This consistent health regeneration is fundamental for early game survival, allowing players to absorb hits and conserve potions, forming the backbone of their initial progress.
