PEAK Best Items Tier List 2026: S-Tier Picks Ranked Differently for Solo and Co-op

Verified on PEAK Early Access, April 2026. Item effects include The ROOTS Update (Mesa biome items). Values may change with future patches — verify in-game at Ascent 6 and above.

Most PEAK tier lists rank items once and leave it at that. The flaw: a 7-slot solo pack and a 4-player coordinated loadout are two different inventory problems. Scout Effigy is dead weight solo and S-tier the moment a teammate dies in co-op. Rope Spool is situational alone but becomes a force multiplier when one player anchors while another pushes a wall. This list ranks every item twice — once for solo, once for co-op — and explains every tier split.

Quick Start: 4 Items That Win in Every Mode

These items are S-tier in both solo and co-op. Take them whenever you find them:

• Cure-All — 3-charge item that clears all 8 debuff types simultaneously plus full injury heal
• Anti-Rope Cannon — fires 12.5m of climbable rope upward, solves most vertical obstacles
• Chain Cannon — lateral chain traversal for ridges, crossings, and gap sections
• Piton — wall-mounted stamina recovery anchor for sections without natural rest points

How This Tier List Works

Items are scored on four factors: survival impact, inventory efficiency, spawn reliability, and mode dependence. Rare items cap at A-tier — you can’t build a strategy around something you won’t consistently find. Items requiring teammates to function — Scout Effigy, Cursed Skull, Rope Spool at its best — get separate solo and co-op scores rather than a single averaged placement.

Solo scores assume a 7-slot pack. Co-op scores assume coordinated play where no single player carries items from every category — which is how co-op achieves better collective capability while each player stays lighter. If your team doesn’t coordinate loadouts, treat the solo tiers as your baseline.

S-Tier: Grab These Every Single Time

Cure-All (Solo: S | Co-op: S)
No item in PEAK covers more ground per inventory slot. A single Cure-All removes poison, frost, thorns, drowsy status, spores, curse, and full injury — all eight major debuff types — with 3 charges per item. Compare this to Antidote, which removes poison only, or the Medkit, which handles injury and poison but not cold or curse. Cure-All doesn’t just outperform those items; it makes them redundant in any slot it occupies. The only reason to pass on a Cure-All is if you already have two — a third displaces a traversal tool you’ll need before the next emergency.

Anti-Rope Cannon (Solo: S | Co-op: S)
The upward-firing cannon creates 12.5 meters of climbable rope above the deployment point — enough to clear Alpine overhangs and most Caldera walls in a single use. Solo, it’s your primary unstuck tool when stamina runs out mid-wall. In co-op, the lead climber fires from above a section so the rest of the team follows without spending their own traversal tools. The Anti-Rope Cannon and Chain Cannon are a pair: together they solve almost every obstacle in the game. Carry both when possible; carry one when you have to choose.

Chain Cannon (Solo: S | Co-op: S)
Where the Anti-Rope Cannon fails — horizontal gaps, ridge traversal, lateral sections requiring sideways movement — the Chain Cannon closes the gap. It pins a chain to ground-level surfaces and lets you swing and climb sideways. In our testing across multiple Alpine and Caldera runs, the most common cause of avoidable deaths is a long gap section with no rope tool — the Chain Cannon eliminates that failure mode entirely.

Scout Effigy (Solo: C | Co-op: S)
The biggest tier split in the list. Solo, the Scout Effigy revives a dead teammate — and you don’t have any. It’s a slot wasted on a function that can never trigger. Co-op, it’s a single-use death reset that keeps a run alive when someone takes a bad fall at Caldera. In groups of 3 or more, carry one per two players. In duos, one between the pair is the correct ratio. Never grab this solo; never skip it in a coordinated group.

A-Tier: Strong — Prioritize When You Find Them

Piton (Solo: A | Co-op: A)
Pitons mount to any climbable surface and provide passive stamina regeneration while hanging. The real value isn’t the healing itself — it’s route segmentation. On Alpine and Caldera runs, carrying two pitons lets you break a long wall into survivable sections when no natural ledge exists to rest on. Each piton handles roughly 3–4 heavy use cycles before breaking, so place them deliberately at sections you know will cost significant stamina rather than treating them as backup.

Magic Bean (Solo: A | Co-op: A)
Plant on a suitable surface, wait approximately 15 seconds, and a climbable beanstalk grows — bypassing a full vertical section entirely. The growth delay is the limitation: you can’t use this reactively mid-fall or mid-crisis. The correct use is predictive — place the bean at a section you can see coming while you catch your breath at a natural ledge or piton. In co-op, one player plants while teammates rest at a piton, then everyone climbs when the stalk is up. Magic Beans create new route options rather than solving existing problems, which is why they earn A-tier despite the timing constraint.

Medkit (Solo: A | Co-op: B)
Solo, the Medkit is your only full injury heal — 100 injury removed plus poison and spores cleared — making it a necessary survival anchor when Cure-All is unavailable. In co-op, the Faerie Lantern provides passive team-wide healing over time, and one player carrying Cure-All while another carries support tools collectively makes the single-target Medkit redundant in most group loadouts. If your co-op team doesn’t run a dedicated support player, treat Medkit as A-tier regardless.

Rope Spool (Solo: B | Co-op: A)
The clearest B-to-A mode shift in this list. Solo, the Rope Spool delivers the same 12.5m of rope as the Anti-Rope Cannon — but since you’re already carrying the cannon, the spool is redundant in most cases. Co-op changes the math: one player anchors a rope from above a hard section while another climbs without spending their own traversal item. Two players crossing a difficult wall using one player’s single item is the efficiency ratio that earns A-tier in groups.

Heat Pack (Solo: A* | Co-op: A*)
Frost in the Alpine biome cuts stamina regeneration significantly — and it compounds across a long wall. Heat Pack removes 360 frost, resetting all cold accumulation in one use. Non-negotiable before entering Alpine. In every other biome (Shore, Tropics, Roots, Mesa), the frost mechanic doesn’t apply — drop this slot for food or a traversal tool instead. The asterisk means it’s A-tier inside Alpine and off your priority list everywhere else.

Ancient Effigy (Solo: B | Co-op: A)
Revives dead players at campsites and grants bonus items if no scout died in that segment. Solo, neither function applies — your solo death ends the run regardless of the effigy. Co-op, it becomes the run’s safety valve, particularly at Ascent 3 and above where deaths compound quickly. One per team is the right carry; the bonus item incentive is secondary to having the death reset available.

B-Tier: Situational — Worth Taking When Core Slots Are Filled

Faerie Lantern (Solo: B | Co-op: A–B)
Slowly heals all status effects to nearby players over time. Solo, the passive slow-heal is inferior to Cure-All’s instant effect in every urgent scenario — and urgent scenarios are how most runs end. In a tightly grouped co-op team moving together through a biome, it provides continuous passive support that accumulates meaningfully over time. Rises toward A-tier in coordinated duos where both players stay close; drops to B when the team spreads out and the area effect misses half the group.

Bugle of Friendship (Solo: D | Co-op: B)
Grants 10 seconds of infinite stamina to all nearby players. The limitation: 10 seconds is short, the activation is slow, and all players must be in range simultaneously. In 3–4 player groups with voice coordination, you can synchronize the buff for a specific brutal crossing — that’s the scenario that earns B-tier. Completely useless solo. Skip it in duos unless you’re specifically coordinating a single hard section.

Portable Stove (Solo: B | Co-op: B)
Doubles most food’s hunger value and slowly removes frost. Efficient on long Caldera runs where food is scarce and every calorie compounds across multiple sections. Skip on shorter biome runs — the stove takes a slot that a traversal tool would use better if your food situation is already stable.

Biome-Specific Items — Mesa (Parasol, Sunscreen, Aloe Vera)
These items are A-tier specifically in Mesa and C-tier outside it. The Parasol removes fall damage and enables tornado navigation — both essential mechanics in a biome where tornadoes are a primary hazard. Sunscreen provides 90 seconds of protection per use (3 uses total) against sunburn damage. Aloe Vera heals sunburn directly. Carry at least one Mesa environmental item before entering the biome.

C-Tier and D-Tier: What to Skip and Why

C-tier items have real but narrow value that a better item in the same slot outperforms. Antidote removes poison — but Cure-All does that plus seven other debuffs. Lantern provides light and removes 150 frost — but Heat Pack removes 360 frost for the same slot. Pandora’s Lunchbox clears all debuffs but inflicts random new ones, making it net neutral at best and a liability if the randomized replacement is worse. Carry these only when nothing better spawned.

D-tier splits into two groups. Achievement items — Bing Bong, Bugle, Flying Disc, Ancient Idol — exist purely for badge collection. Carry them on dedicated badge runs, never during summit attempts. The Ancient Idol is heavy enough to measurably slow movement and reduce carry capacity. Hazard items — Banana Peel, Blowgun, Dynamite — have no constructive value in a serious run.

Cursed Skull is the one D-tier item with a genuine exception: it kills the scout carrying it to revive every dead teammate simultaneously. Solo it’s D-tier (kills you, no teammates to revive). In a co-op Ascent run where multiple players have died and the team is one death from wipe, it’s a B-tier last resort. Situationally powerful; almost never the correct default carry.

Solo vs. Co-op Starter Packs

Build your loadout around these core items and fill remaining slots based on what spawns in your current biome.

Solo starter pack (7-slot inventory):

Swap slot 7 for Heat Pack when entering Alpine. Swap Medkit for Pirate’s Compass on the first biome when your item slots are empty and you need to find gear fast.

Co-op starter pack (2-player split):

Both players carry food independently. In 3-player groups, the third player takes Ancient Effigy, a second Cure-All, and the relevant biome environmental item (Heat Pack for Alpine, Parasol or Sunscreen for Mesa). Once you’ve locked your loadout, the next skill jump is in your movement — see our PEAK advanced techniques guide for crouch jumping, physics exploits, and expert climbing lines.

Frequently Asked Questions

Is Cure-All the best item in PEAK?
By survival value per slot, yes. No other item clears 8 debuff types plus full injury healing with 3 uses. The only reason to pass on one is if you already have two — a third Cure-All displaces a traversal tool you’ll likely need before your next emergency hits.

Do tier rankings change at higher Ascent levels?
Yes. Ascent 3 and above adds faster hunger depletion and heavier carry weights. At these levels, Portable Stove rises from B to A-tier because the cooking efficiency multiplier compounds across a longer, harder run. Revive items (Scout Effigy, Ancient Effigy) also rise in co-op priority because the margin for error drops to near zero — a death that’s recoverable at Base difficulty becomes a run-ender at Ascent 5.

Is solo PEAK actually harder than co-op?
The map is identical in both modes — no mechanical difficulty multiplier exists for party size. Solo feels harder for one specific reason: you can’t specialize inventory. Every slot has to cover both traversal and survival, whereas co-op lets you split those categories. Many experienced players find solo cleaner once they know the routes, because you never lose items when a teammate dies and you don’t need to coordinate timing on every section.

What’s the worst biome for unprepared loadouts?
Alpine, consistently. Frost accumulation reduces stamina regeneration faster than any other biome mechanic, and it compounds across a long wall — a 30-second climb that was manageable in Tropics becomes a stamina-out situation in Alpine without a Heat Pack. Always carry one before entering Alpine. It’s worth giving up a lower-priority slot to guarantee this.
