How to Get A Rank

Tips to Get A Rank
Use the Gunlance as Your Primary Apply Buffs Before The Fight Use Evasion Mantle During the Early Stages Focus Strike When Able Take Advantage of Your Shield Avoid Bringing a Support Hunter

Use the Gunlance as Primary

Best Weapon Set for Solo
Ajara Gunpike II ▼Set B: Gunlance▼

If you're aiming for an easy A Rank against the Mizutsune, we recommend using the Gunlance. This weapon allows you to deal massive damage to Mizutsune thanks to its Wide Shelling, while still keeping you safe from its attacks thanks to the Gunlance's shield. The set has Ambush, which boosts your attack after doing a sneak attack on Mizutsune.

Gunlance Weapon Guide

Use Charged Shelling to Charge Wyvern's Fire

Charged Shelling not only deals a lot of damage, but also quickly charges your Wyvern's Fire. Shooting six total Charged Shells is enough to charge one shot of Wyvern's Fire, so take advantage of this and shoot Wyvern's Fire often.

Perform Wyrmstake Full Blast When Able

Whenever Mizutsune goes down, take advantage of it and deal massive damage with a Multi Wyrmstake Full Blast. If you have Wyvern's Fire charges, use those as well as the wind-up animation is shortened after a Multi Wyrmstake Full Blast.

Apply Buffs Before The Fight

Before the fight officially begins, drink the Demondrug so that you get the Attack Power buff. This will give you enough of an Attack Power boost that lasts for 30 minutes, giving you a damage boost for the entire fight.

Additionally, eating the Well-Done Steak that comes with Set B helps you gain max Health and Stamina, which will help in the fight. It also activates Protein Fiend I, which gives a bonus of 15 attack for 2 minutes.

You can do all of these while riding your Seikret to save time as you can move quickly while consuming buff items.

Use Evasion Mantle During the Early Stages

The Set B preset includes an Evasion Mantle, which can be used during the early stages of the fight to boost your offensive potential. When activated, it allows you to perform a Perfect Dodge.

If timed correctly, this grants a 1.2x increase to Attack Power for 10 seconds, giving you a strong edge in combat. Additionally, as the Set B armor contains Adrenaline Rush, you also get +20 Raw Attack Power for 30 seconds.

Focus Strike When Able

Whenever Mizutsune gets Wounds, make sure to perform a Focus Strikes as it deals a lot of damage while also interrupting Mizutsune's attacks.

A Weak Point Appears After Charged Water Blast

Additionally, a weak point appears in Mizutsune's mouth after it performs its Charged Water Blast, which you can immediately Focus Strike to stagger it.

How to Use Focus Mode and Focus Strike

Take Advantage of Your Shield

The Gunlance's large shield is able to easily block Mizutsune's attacks, including its water beam. You can take advantage of this by blocking Mizutsune's attacks and attacking right after. This is especially useful against Mizutsune's water beam, as blocking the initial attack *makes you immune to the rest of the attack.

Additionally, performing a Perfect Guard not only activates the Gunlance's Offensive Guard, but also allows you to shoot a sped up Wyvern's Fire. This does, however, leave you open for attack while charging, so make sure you are safe before committing.

How to Block and Perfect Guard

Avoid Bringing a Support Hunter

If you're not doing the Mizutsune challenge quest with a friend, try to do it solo without a support hunter. This means the monster's HP won't scale higher, and you'll always have the monster's attention, making it more predictable.
