Switch Axe Guide
Switch Axe carries momentum through every transformation. The switch gauge and the length of each opening determine when axe form's reach and movement cover its refill, and when the monster will stay still long enough to spend that gauge in sword form. Build Amped State, then commit to Zero Sum Discharge only when its finisher will land.
You cannot hold a shield guard. Hops, rolls, and attacks that move you are your ways to leave an incoming attack's path without sheathing.
This guide reflects Iceborne's final balance. Use the in-game Hunter's Notes for weapon controls; the official manual covers general controls. Combat Mechanics explains why the same swing hits for different numbers. Every move is in Motion Values.
If this weapon is new to you, try it in the Training Area first. Use the in-game Hunter's Notes to practice its basic attacks; this guide explains how to connect them into a hunt.
Gauge, Amped, Power Axe
The Switch Gauge refills while you use axe form and is consumed while you use sword form. If you try to morph with too little gauge, the weapon forces you to reload instead of attacking. Morph back to axe before the gauge empties. Filling the switch gauge does not activate Amped State; landing sword hits builds that state separately.
When the sword lights up, Amped State is active and your hits create phial bursts. extends both Amped State and Power Axe Mode. can reduce the number of sword hits needed to reach Amped State, so check whether it changes a useful breakpoint for your attack sequence.
Finish Wild Swing with Heavy Slam to activate Power Axe Mode. It adds a part-damage modifier to axe attacks, which helps cause part breaks and part flinches without directly increasing damage to the monster's health. It does not strengthen the sword's phial.
Choose a phial type to match the build's purpose:
- Power — applies
1.17xto true Attack in sword form. Start here for a raw-focused build. - Power Element — applies
1.45xto weapon element in sword form. Use it when the weapon's element matches a target weakness. - Exhaust, poison, paralysis, and dragon — add the effect named by the phial to sword attacks. Choose one only when that effect serves the hunt.
Amped State bursts are not full element ticks. They apply less element and status than a normal sword hit.
Sword and morph
Use axe form to move, refill the switch gauge, and maintain Power Axe Mode when the hunt calls for extra part damage. Change to sword form when you have enough gauge and can stay on the part you want to hit. Morph Slash moves you forward while changing form. Start it early enough for that movement to carry you out of an incoming attack's path; the morph itself is not a guard or counter.
Do not spend the rest of the gauge just because the monster flinches. If the sword is about to click empty, return to axe before the forced change interrupts your sequence. From axe form, trying to enter sword form below the gauge threshold reloads instead of attacking.
Sword attacks consume sharpness, so preserve enough of your chosen sharpness color for the opening in which you plan to use them.
Zero Sum Discharge
When Amped State is active, an Element Discharge that connects latches you into Zero Sum Discharge. In Iceborne, you can instead clutch onto a part during Amped State and begin Zero Sum Discharge without the grounded thrust. The attack requires Amped State, but it does not require you to enter a full sword morph first.
Keep pressing the attack input to continue the ticks and reach the finisher. Ending the discharge early applies a 0.7x raw-damage modifier to that finisher, so reserve the full sequence for an opening that will last.
The ticks use your current sharpness modifier. The finisher is instead calculated with the green sharpness modifier, whatever color the weapon currently has.
Fight loop
The basic loop is to refill in axe form, morph to sword, build Amped State, and return to axe before the switch gauge runs out. Amped State remains active when you morph, so you can refill without rebuilding it. Use the movement of Morph Slash only when its path both clears the next attack and keeps you near the chosen part. Once Amped State is active, clutch onto that part and use Zero Sum Discharge only when the monster will remain still long enough for the finisher; a brief flinch is not enough.
At the start of the hunt, use Flinch Shot when the monster is not enraged, your slinger is loaded, and a wall is in front of its head. The collision creates a knockdown in which you can wound the part you plan to attack. Switch Axe is a heavy weapon, so one clutch weapon attack creates the wound. Against Great Jagras, target the head or the inflated belly.
During a knockdown, attack in sword form while Amped State is active. If the opening is long enough for a full Zero Sum Discharge, clutch onto the chosen part first unless you are already attached. If the opening is too short for the finisher, stay grounded and leave yourself time to disengage.
When the monster starts its next attack, stop before another sword commitment. Use Morph Slash only when its movement carries you out of the attack's path; otherwise hop or roll clear. None of these actions can be held like a shield guard.
Skills
When hits start to hurt, address the defensive priorities before adding more . Staying active matters more than a small attack increase that does not prevent the next faint. Getting Started explains the meal, , and Armor Sphere priorities. Combat Mechanics explains Defense, the benefit of reaching 20 elemental resistance, and . To receive the full affinity bonus from that skill, hit a wounded part whose sever hitzone is 45 or higher.
Priorities
For a physical starting point, use a Power phial and the following priorities.
| Offensive | Why |
|---|---|
| Amped State and Power Axe Mode last longer, so you spend less of an opening rebuilding them. | |
| Lv 1 | Raises base attack when the equipped weapon has no active element or status. Skip it on an elemental build. |
| Lv 3 | Adds affinity when you can keep the sword on a part whose sever hitzone is 45 or higher; wounding that part supplies the rest of the skill's bonus. |
| plus weapon affinity to 100%, then Lv 3 | only multiplies affinity you actually have. Affinity past 100% does nothing. |
| Adds attack and affinity while the monster is enraged. Clutch-claw turns and Flinch Shot help bring that state on, but one Flinch Shot does not always enrage the monster. Lv 7 needs . | |
| Keep white or purple | Sword hits consume sharpness, and Zero Sum Discharge ticks scale with the current sharpness color. Choose one maintenance option from Keep a color below. |
| Defensive | Why |
|---|---|
| Lv 3 | Raises the health cap to 200 with the meal. |
| Armor Sphere | Raises Defense at the smithy. Spend them on armor you expect to keep when hits start to hurt. |
| 20 matching resistance | At 20 of a resistance you do not catch that blight. , , , , — or . |
| A chance to reduce the damage you take. Lv 5 needs . | |
| Lv 3 | Stops stun. |
In a group, Lv 1 prevents knockbacks that can interrupt your sword sequence. It does not stop you from flinching teammates, and it is normally unnecessary when hunting alone.
Often added, not required:
| Skill | Why |
|---|---|
| Builds Amped State faster. Use it when the bonus removes a sword hit from the attack sequence you use. | |
| Lv 4+ | Extra attack in remaining slots. Lv 4 also adds 5% affinity. |
| Lv 1 | Can add a slinger-ammo drop to the clutch weapon attack. Switch Axe already wounds in one clutch attack. |
| Raises Attack at full health. Any unrecovered damage turns it off. | |
| Extra attack while recoverable (red) health is on the bar. Pair with or . | |
| Conditional affinity while your stamina is full. Hops compete with that condition because they spend stamina. | |
| Raises Attack, element, and status buildup after you recover from a blight or abnormal status. | |
| Conditional affinity and reduced stamina depletion. Because you cannot activate it on demand, it is less reliable than affinity tied to the part you choose to attack. | |
| Longer invulnerability on hops. Morph attacks are not evasive by themselves. | |
| With Power Axe Mode, breaks parts faster. It does not raise damage to health. | |
| Extra rounds do not increase Flinch Shot damage or wall-collision damage. | |
| Adds attack and defense after a faint. It helps a hunt recover from a mistake but is not a reason to plan one. |
Keep a color
Choose one maintenance method that fits the weapon's sharpness gauge. Preserve white or purple for sword attacks and Zero Sum Discharge ticks; the finisher still uses the green sharpness modifier.
| Skill | What it does |
|---|---|
| Adds sharpness when the gauge is not already full. | |
| No sharpness loss on criticals. | |
| No sharpness loss for a fixed time after you sharpen. | |
| Reduces sharpness loss on average. | |
| The stronger set-bonus version. | |
| Removes cycles from sharpening, letting the full action fit into a shorter opening. |
Adjustments for survival
Use these comfort skills when fainting, healing, or interruptions keep breaking your hunt. As those problems become less frequent, move the decoration slots back to the offensive priorities.
| Skill | Why |
|---|---|
| Increases the health restored by healing effects. | |
| Drink faster. Sheathe, move, then drink. | |
| The red (recoverable) part of the health bar returns faster. | |
| More Defense on top of Armor Sphere. | |
| Lv 3 prevents elemental blights; lower levels shorten their duration. Use it when matching resistance cannot reach 20. | |
| Survives one otherwise fatal hit when health is above its activation threshold. The next hit can still faint you. | |
| Mantles come back faster. Temporal and Rocksteady make clutch attacks safer. | |
| Reduces or prevents roar reactions at the levels described by the skill, preserving openings that a roar would interrupt. | |
| Makes hops cover more ground while sword form limits your walking speed. | |
| Reduces the fixed stamina cost of hops and similar actions. It does not reduce continuous stamina drain. | |
| Reduces continuous stamina drain from actions such as sprinting. | |
| Sometimes does not consume the item. |
Styles
| Style | Skills |
|---|---|
| Power Element | Use the attack skill that matches the weapon's element, such as , plus or . Do not use . |
| Exhaust, poison, or paralysis phial | The phial supplies its listed buildup in sword form. Decide whether that hunt benefits from the effect before giving it build space. |
This hunt
These skills do not belong on every set, but each can be more valuable than another general offensive skill against the right monster.
| Skill | When |
|---|---|
| Stops tremor from knocking you off Zero Sum Discharge. | |
| Prevents wind-pressure reactions, including pressure too strong for , from interrupting an attached Zero Sum Discharge. | |
| Greatly improves evasion invulnerability and reduces stamina depletion while a blight or status is active. It does not add Attack. | |
| Lv 3 prevents Defense Down; lower levels shorten its duration. Use it only when the target can inflict the ailment. | |
| or | Grants protection from roars, wind pressure, tremors, and small knockbacks while a mantle is active. Only the True version reaches the highest levels. |
| Makes a Dung Pod more likely to send a monster away. | |
| Increases Flash Pod range. The wider flash helps ground a flying monster for an opening. | |
| Increases explosive damage when barrel bombs are part of the hunt plan. | |
| Stronger elderseal on a dragon-element Switch Axe. | |
| Increases the attention drawn by your attacks. In a group, take it only when you have deliberately chosen to hold the monster's attention. | |
| Prevents environmental damage from the Rotten Vale while you continue attacking in sword form. | |
| Reduces stamina depletion only while health is at 40% or lower, so it does nothing during the healthier part of a hunt. | |
| Increases the health restored by environmental interactables. |
Skills that look better than they are
- — sword already resists bounce. It does not make a hard hide a good target.
- Purple sharpness does not make the Zero Sum Discharge explosion stronger than green because the explosion always uses the green sharpness modifier. The preceding ticks still benefit from white or purple sharpness.
- does not give Switch Axe a shield.
- does not increase a grounded sword hit.
- does not activate from a morph hop because the hop is not a slide.
Settings
Set Automatic Sheathe to Manual so you decide when to sheathe instead of letting the setting interrupt a form transition.
Before a long sword discharge, center the camera on the head or wound you mean to finish on. A camera left on the body after an axe approach often dumps the sword finish onto a weaker zone.
