Here's how breaking parts and severing tails works in Monster Hunter Outlanders: the rewards and benefits, which parts you can break on each large monster and what they drop, and the weapons, skills and squad members that break parts best. Checked on November 11, 2026.
Part Break Rewards and Benefits
You Get More Materials
Breaking a part gives you a high chance at that part's materials. Some materials you need to craft gear are much easier to get by breaking a specific part.
Check Part Rewards in Free Hunt
The rewards for each monster in Free Hunt include part-break rewards, and the part to break is shown at the top left of each material. If you need a specific material for gear, check there whether breaking a part can get it.
Broken Parts Open Up the Monster
Monsters often flinch when a part breaks, which can cancel the attack they're doing. Breaking legs or wings can leave them unable to move for a while, so it's a good time to attack. Severing a tail makes them flinch too.
Some Monsters Get Weaker
On some monsters, breaking a certain part weakens them. For example, breaking a Flying Wyvern's wings makes it harder for it to fly. Each monster has its own weakening effect.
Radiant Monsters: Break the Weak Part to End the Rage
Radiant monsters, new to Outlanders, have their own weak part. Breaking it ends their Radiant Rage.

Tail Sever Rewards and Benefits
Carve the Severed Tail for Extra Materials
On monsters with a tail, you can carve the tail after severing it. You get these carves on top of the quest rewards, so go for the tail when you want more materials.
Some Monsters Lose Attacks
On some monsters, such as Rathian and Tzitzi-Ya-Ku, breaking a certain part limits the attacks they can use. It's especially worth it on monsters that inflict troublesome status effects, so go for those parts.
How to Break Parts
Deal Enough Damage to the Part
You break a part or sever a tail by dealing a set amount of damage to that part. You need to hit it directly, so make sure your attacks land on the part you're aiming for.
Broken Parts Are Easy to Spot
A broken part turns red in the on-screen display, so you can tell at a glance. The monster also keeps a visible wound there, so once a part is broken, switch to another one.
Use Lock-On on the Part
Outlanders lets you lock on to a specific part with Lock-On, which makes part breaks much easier to aim for. It keeps tracking the part even on big monsters, so use it often.
Check Breakable Parts in the Monster Field Guide
The weak points page of the Monster Field Guide marks which parts are breakable, and shows how well Sever, Blunt and Ammo attacks work on each part. More diamonds mean more effective.
Breakable Parts and Rewards by Monster
Here are the breakable parts of every large monster and the materials you get by breaking them. Small monsters have no breakable parts. The table leaves off the grade at the end of each material name (a Roman numeral that changes with the rank); see each monster's page for drops by rank.
The materials column uses the part shown on each reward, so its part names can differ from the breakable parts list (for example, Radobaan). A dash means no part-break materials are listed for that monster.

Best Weapons and Boosts for Breaking Parts
Match Your Attack Type to the Part
Each part has an attack type it's weak to: Sever, Blunt or Ammo. If you're farming a monster's part-break materials, check that part's ★ on the monster's page and bring a weapon of the type that works best on it.
Severing Tails Needs Sever Damage
Hammer is a Blunt weapon, so it can't sever tails, though it can still break the head and other parts. Heavy Bowgun can sever tails only with Slicing Ammo, so switch ammo before you go for the tail. Fire it from behind the monster, where the head and wings won't block your shots.
Hammer Guide / Heavy Bowgun Guide
Great Sword Is Great at Breaking Parts
Great Sword hits hardest with charged slashes, and its damage goes up through three charge levels. That makes it great at breaking parts.
Equip Armor With Breaker
The Breaker skill raises the damage your attacks build up on parts: ×1.1 at Lv1, ×1.2 at Lv2 and ×1.3 at Lv3.
Adventurers and Buddies That Boost Part Breaks
Some adventurers raise part break efficiency or part damage through their skills and insights, and some buddies do it through their support effect. Keep them in mind when you farm a monster's materials with a squad you use often.
