Palworld Mammorest Guide: It Takes 2x Damage From 3 Elements (Not Just Fire)

Every Mammorest guide tells you to bring a Fire Pal. That’s not wrong, but it’s only a third of the picture — and it skips the one trick that makes this catch genuinely fast instead of a 90-second slugfest.

Mammorest is Grass/Ground, and Grass eats double damage from three elements, not one: Fire, Ice, and Water [3]. Ice does something the other two don’t — it can freeze Mammorest solid, because unlike Ice- and Fire-type Pals, Mammorest has no natural immunity to the freeze effect [2]. That’s the gap this guide fills: the mechanic, the numbers, and a capture routine built around it.

Quick Start: Catching Mammorest in Under 2 Minutes

If you just want the pal, skip straight to this checklist. Everything below explains the reasoning.

• Bring one Fire, Ice, or Water attacker — Ice is the priority pick if you have one, for the freeze (see below)
• Craft or carry Mega Spheres at minimum; Ultra works for standard-level Mammorest, save Legendary Spheres for the Alpha
• Target the standard spawns first (level ~18–20) before attempting the level 38 Alpha
• Whittle HP down with your elemental attacker, don’t melee with a mismatched Pal
• Land a hit from behind if you can — it’s a flat capture-rate bonus regardless of HP
• Throw when HP is in the last 1–5% sliver, not at 20% — the last stretch of HP swings catch odds far more than the difference between 50% and 20% does

Mammorest at a Glance

Confirmed stats and identity, cross-checked against Palworld Wiki and PalDB [1][7]:

Sell price is listed as 945 gold on Palworld Wiki and 2,220 gold on PalDB [1][7] — the two sources disagree, likely reflecting different game-version snapshots, so treat either as a rough baseline rather than a guaranteed figure until you check your own game’s sell menu.

The Real Weakness: It’s Not Just Fire

Grass-type Pals take Super Effective damage — a flat 2x multiplier — from Fire, Ice, and Water attacks [3]. That multiplier is what actually shortens the fight: a Pal that would take six hits at normal damage only needs three at double damage, and every extra second you spend fighting is a second Mammorest’s own attacks can knock you or a partner Pal out of position. Most Mammorest write-ups stop at “bring fire,” which works, but it means players who only own Ice or Water attackers have been told they’re at a disadvantage when they’re not. If your roster is built around Jormuntide, Penking, or any Water/Ice specialist, you’re already carrying a Mammorest counter.

The one thing Fire can’t do that Ice can: freeze it.

The Freeze Trick Fire Can’t Match

Every Ice-element attack, plus the Ice Grenade and Ice Mine, has a chance to freeze a target solid for about three seconds — fully immobilizing it and interrupting whatever attack it was channeling [2]. Ice- and Fire-type Pals are immune to this. Mammorest is neither. That means an Ice attacker doesn’t just hit Mammorest for double damage — it can also lock it in place while you close distance, land a follow-up hit, or simply create breathing room to reposition.

Use this decision tree when you’re picking your attacker for the fight:

• If you own an Ice-type Pal (Frostallion, Cryolinx, Kingpaca Cryst) — lead with it. Double damage plus a chance to freeze-lock Mammorest mid-charge is the strongest combination available.
• If you only have Fire — still double damage, still a solid pick, just without the freeze utility. Fine for solo fights where you have room to kite.
• If you’re fighting the level 38 Alpha alone — prioritize Ice regardless of what else you have. The freeze window is the difference between tanking a full combo and getting a clean opening to disengage or heal.

Best Capture Method, Step by Step

In my own runs, the fights that went sideways were the ones where I threw the sphere too early at 15–20% HP out of impatience. Palworld’s capture math rewards patience more than gear: dropping a Pal from roughly 20% to near-death swings your catch odds up by a noticeably larger margin than any single sphere upgrade does. Combine that with a back-hit, which adds a flat bonus on top regardless of level, and a mid-tier sphere out-performs a top-tier sphere thrown at the wrong moment.

Where to Find Mammorest

Standard Mammorest spawns in Windswept Hills, Marsh Island, Forgotten Island, the northwestern Bamboo Groves, and the southern Astral Mountains [1]. The nearest reliable early-game spot for most players is right around the Grassy Behemoth Hills teleport point, where it shows up alongside other early Grass-type Pals [6].

The level 38 Grass Alpha roams east of Grassy Behemoth Hills, in the Plateau region, near (189, -478) per Palworld Wiki [1]. Alpha spawns patrol a wider area than a single point, so treat this as the general zone to head to rather than an exact pin.

Lumber and Mining Work Rate vs Other Large Pals

Mammorest sits at Level 4 for Planting, Lumbering, and Mining [1][7] — solid, but not top-tier. Level 8 specialists like Aegidron (mining) and Celesdir Noct (lumbering) out-produce it on paper, and mid-pack options like Astegon and Silvegis (both Level 6–7) beat it too [4][5].

Mammorest Cryst, the Ice/Ground subspecies, hatches from a Huge Frozen Egg rather than the standard Mammorest’s egg pool, and trades base Mammorest’s Planting suitability for Cooling instead — worth breeding toward specifically if you’re building a refrigeration-heavy base rather than a farming one [8].

Here’s the part the tier lists miss: that Level 4 rating is only Mammorest’s base-assignment number, for when it’s parked at a Pal Box doing passive work. Its Partner Skill, Gaia Crusher, only kicks in while you’re actively riding it — and while mounted, it boosts logging efficiency by roughly 220–500% and mining efficiency by 500–2,000%, scaling with Pal Condenser rank [1]. In practice, that means Mammorest is a mediocre passive base worker but one of the best active gathering mounts in the game — you get far more value hopping on its back to clear-cut a forest or strip a rock node yourself than leaving it assigned to a base slot. See our rideable Pals guide for saddle requirements and other mounts worth the investment, and our best worker Pals guide if you want pure base-assignment efficiency instead.

Which Player Type Should Bother With Mammorest?

FAQ

Is Mammorest actually weak to Ice, or just Fire?
Both, plus Water — all three deal double damage to Grass-type Pals. Ice is the better pick of the three specifically because it can also freeze Mammorest solid for a few seconds, which Fire and Water cannot do [2][3].

Is Mammorest good for my base, or should I ride it?
Ride it. Its Level 4 work suitability is average for a passive base assignment, but its Gaia Crusher partner skill multiplies gathering speed by several hundred percent while mounted — a gap wide enough that active use beats passive assignment for almost every player type [1].

Should I fight the Alpha Mammorest or the regular one first?
Catch a regular one first if this is your first attempt. The Alpha’s higher HP pool and lower 0.7x catch multiplier make it a rougher, slower fight, and the regular version already has the stats and partner skill you want for gathering [1].

Is Mammorest Cryst just a reskin, or does it work differently?
It works differently. Beyond the Ice/Ground typing swap, Cryst replaces base Mammorest’s Planting duty with Cooling — genuinely useful if your base needs refrigeration capacity, not just a cosmetic snow variant [8].

Key Takeaways

Mammorest rewards the player who reads past “bring Fire.” Ice does the same double damage and can freeze it solid because it isn’t an Ice/Fire-immune type itself — that’s the fight-shortening edge most guides never mention. And once you’ve caught it, its real value isn’t sitting at a Pal Box on Level 4 lumber duty; it’s on your hotbar as a mount, where Gaia Crusher turns an average work-suitability Pal into one of the fastest ways to clear a forest or a rock field in the game. For the rest of the region’s Pals, our Palworld beginner’s guide covers where Mammorest fits into an early-game roster, and our breeding guide covers how to work toward Mammorest Cryst if you want the Ice/Ground variant too.
