Binding of Isaac Best Items — 15 Items That Carry Any Run

By the Choost Games team — indie game developers behind Granny's Rampage and Granny's Gambit. We play what we recommend.

Sacred Heart, Brimstone, and Mom's Knife are the three strongest items in The Binding of Isaac: Repentance — each individually capable of turning a dying run into a guaranteed clear. With over 700 items in the game, knowing which ones are run-winners and which are trap picks is the difference between streaking victories and dying on Depths II repeatedly. These 15 items carry any character, any route, any seed.

The Run-Winners

Sacred Heart — Homing tears plus massive damage up plus health up. It does everything. The homing effect means you can focus on dodging instead of aiming, the damage multiplier makes every subsequent damage item better, and the health bonus keeps you alive to use it. If you see Sacred Heart in any item room, Angel deal, or Crane Game, you take it. Always.

Brimstone — Replaces your tears with a chargeable blood laser that pierces all enemies and obstacles. The damage is enormous, the piercing clears rooms in one sweep, and it synergizes with nearly every tear modifier in the game. Brimstone + any damage up is a won run.

Mom's Knife — The highest raw DPS item in the game when used correctly. Replaces tears with a throwable knife that deals damage based on charge distance. The skill ceiling is high — you need to manage charge timing and distance — but mastered Mom's Knife kills every boss in the game in seconds.

The Build Enablers

Cricket's Head — 1.5x damage multiplier. Simple, universal, and multiplicative with everything else. There's no build where Cricket's Head is bad. It makes good items better and mediocre items viable.

Polyphemus — Massive damage up that makes each tear hit like a truck but reduces fire rate. The tradeoff sounds bad until you realize that one-shotting enemies means fire rate doesn't matter. Polyphemus turns the first three floors into a breeze and keeps scaling because the damage multiplier applies to everything.

Tech X — Chargeable tear rings that deal damage over their entire area. The rings are enormous, the damage scales with charge time, and the item has positive synergies with almost everything. Tech X + Brimstone creates a ring laser that clears the screen.

Dead Eye — Consecutive hits increase your damage multiplier up to 2x. Misses reset it. In the hands of a player who can aim, Dead Eye is a free damage doubler. In the hands of someone who misses frequently, it's a frustrating trap. Skill-dependent, but its ceiling is absurd.

The Utility Legends

Blank Card — Reusable card effect. The card itself determines the power level — Blank Card + Jera (doubles all pickups) creates infinite resources. Blank Card + Algiz (invincibility shield) makes every boss trivial. The item is only as good as the card you find, but the best combinations break the game.

Book of Shadows — Temporary invincibility on use. Against bosses with learnable patterns, this means free DPS windows with zero risk. The cooldown is short enough to use every boss phase, making it a reliable safety net for the entire run.

The Wafer — All damage taken is reduced to half a heart. Against endgame bosses that deal full-heart damage, The Wafer effectively doubles your health pool. It's not exciting, but it prevents more deaths than almost any other item.

The Sleeper Picks

Gnawed Leaf — You become invincible when standing still. Sounds useless until you pair it with any orbital or familiar that deals damage passively (Cube of Meat, Sacrificial Dagger, flies). Then you stand still and let your familiars kill everything while you're immortal. It's slow, it's boring, and it never loses.

Pyromaniac — Explosions heal you instead of dealing damage. This turns multiple self-damage items (Bob's Brain, Ipecac) from liabilities into healing sources, and makes Bomb-heavy rooms beneficial instead of threatening.

9 Lives — Nine extra lives with reduced stats. The stat reduction sounds scary, but nine chances to win means you can brute-force bosses and rooms that would otherwise end your run. On characters that start with low stats anyway (like The Lost), the penalty is negligible.

Holy Mantle — Blocks one hit per room. On The Lost (who dies in one hit), Holy Mantle is the difference between unplayable and viable. On other characters, it's a free pass on one mistake per room — enough to make sloppy play survivable.

Ipecac — Turns tears into exploding projectiles with massive damage. The self-damage risk from explosions is real, but with practice (or Pyromaniac), Ipecac's damage output trivializes the first four floors and remains relevant against every boss.

Items That Look Good But Aren't

Soy Milk reduces damage to a quarter in exchange for rapid fire rate. The math rarely works out — you need extreme synergies to overcome the damage penalty. Tiny Planet makes tears orbit you, which sounds cool but makes aiming impossible in practice. Cursed Eye gives charged shots but teleports you to a random room if you take damage while charging — the worst tradeoff in the game.

From Choost Games

The Binding of Isaac's item system is one of the great roguelike design achievements — it's a direct influence on how we think about weapon and upgrade design in Granny's Rampage. For more in the genre, see games like Binding of Isaac, the best roguelike games, and games like Enter the Gungeon.

Frequently Asked Questions

What is the single best item in Binding of Isaac? Sacred Heart. It gives homing, massive damage, and health in one pickup. No other item improves every aspect of your run simultaneously. Brimstone is a close second but requires charging, which Sacred Heart doesn't.

Are there items I should never take? Avoid Cursed Eye (teleports you when hit while charging), Soy Milk (unless you have very specific synergies), and Experimental Treatment (randomizes your stats — can improve or ruin your run unpredictably).

How do I find Angel Room items like Sacred Heart? Skip Devil Deals entirely. After passing your first Devil Deal, Angel Rooms start appearing. Donate to Sacrifice Rooms and Confession Booths to increase Angel Room spawn rates. The items are worth the delayed power curve.
