How to Unlock Lagiacrus and Tempered Lagiacrus

Lagiacrus: Reach HR31 and Complete Two Specific Missions

You can unlock Lagiacrus and its Extra Mission, Trembling Blue Currents, by reaching HR31 and completing two specific missions. These missions are "A World Turned Upside Down" and "Forest Doshaguma".

Tempered Lagiacrus: Reach HR41 and Complete Trembling Blue Currents Mission

Completing Lagiacrus' Extra Mission, Trembling Blue Currents, will grant you access to hunting its regular and tempered variant.

Do note that since Tempered Lagiacrus is a Difficulty 8★ monster, it will only start spawning once you've completed the HR40 Assignment, What Lies Ahead. Getting past this assignment allows you to get to HR41+.

What Lies Ahead Mission Walkthrough

How to Spawn Lagiacrus

Rest in Iceshard Cliffs and Set It to Morning, Inclemency

Iceshard Cliffs Morning Inclemency
A way to spawn Lagiacrus and Tempered Lagiacrus is to head over to Iceshard Cliffs and rest in a tent. Set the time to Morning and the weather to Inclemency. Afterwards, check the map if a Lagiacrus has spawned in the Scarlet Forest. While not guaranteed everytime, there is a high chance that doing this can spawn a Lagiacrus or Tempered Lagiacrus.

Lagiacrus can inflict Thunderblight. If your Thunder Resistance is low, make sure to carry Nulberries with you before the hunt as they can nullify the blight.

Before hunting, make sure to always bring Mega Potions and materials to craft them with. Traps, and mantles can also help your hunt go much smoother.

How to Beat Lagiacrus

Lagiacrus Monster Fight Tips








Focus Strike Its Back After Thunder Discharge Attack

After it does its Thunder Discharge attack, its back can become a Weak Point. If its back glows red in Focus Mode, Focus Strike it to stagger Lagiacrus and deal decent damage. This may possibly even knock it down!
How to Use Focus Mode and Focus Strike

Keep Attacking Its Head to Knock It Down

Knock Lagiacrus down by attacking its head. After enough damage is dealt to its head, it'll go down and you'll have a good damage window.

Use the Dam Rubble in Area 15 of the Scarlet Forest

If you and Lagiacrus end up in Area 15 of the Scarlet Forest, make sure to utilize the Dam Rubble trap located by the waterfall. Trigger it with your Slinger to deal massive damage to Lagiacrus. This is especially helpful when fighting its tempered variant.
How to Set and Activate Traps

Use the Unstable Rubble in Area 13 of the Scarlet Forest

As Lagiacrus moves its way toward Area 19 in the Scarlet Forest, it will swim underneath some Unstable Rubble in Area 13. With good timing, you can drop this on Lagiacrus to knock it out and deal huge damage to it!

Use Nulberries to Cure Thunderblight or Increase Thunder Resistance

Lagiacrus can inflict Thunderblight, which paralyzes you if you've accumulated enough of the blight. This leaves you open to lethal attacks that can cart you. Make sure to bring Nulberries to the hunt to cure the Thunderblight quickly.

You can also opt to increase your Thunder Resistance, either through skills, armor, or meals. Reaching 20 Thunder Resistance makes you completely immune to Thunderblight.

Thunderblight Status Ailment Explained

Swim Away from Devastating Discharge

If you fail to deal enough damage to Lagiacrus while underwater, it will initiate its devastating discharge attack. The good news is you can survive this attack by swimming away far enough the moment it starts the attack.

Ascend Upwards to Dodge Underwater Body Tackles

As it's difficult to dodge Lagiacrus' underwater body tackles by evading or swimming sideways, it's more reliable to use the ascend move to dodge this attack.

Attack Its Weakpoint Underwater

After Lagiacarus does its Underwater Thunder Shot, its mouth becomes a Weak Point. After avoiding this attack, immediately cling unto its head and attack it while it's glowing red to deal significant damage!

Let It Charge Into Submerged Rubble

Besides dropping Submerged Rubble on top of Lagiacrus, you can actually bait it to crash into it as well. This still deals a good amount of damage while temporarily immobilizing Lagiacrus. Just remember to dodge its charge before it hits you!

Lagiacrus Underwater Combat

Lagiacrus Underwater Combat Tips




Follow Lagiacrus Down Into the Water

Once you've followed Lagiacrus into Area 19 of the Scarlet Forest and dealt enough damage to it, Lagiacrus will dive into the water to prepare for a devastating discharge attack. Follow the scoutflies or the indicator on the map to approach the edge and dive after the monster!

Underwater Combat Guide

Evade Lagiacrus' Attacks

Once underwater, you can swim around using the directional buttons. You can also ascend or descend to position yourself. Additionally, make sure to dodge Lagiacrus' attacks and projectiles using the evade button.

Use Slinger to Cling Unto Lagiacrus

Your main goal underwater is to deal enough damage to Lagiacrus to stop it from fully charging its discharge attack. One of the main ways of doing this is to aim and fire the Hook Slinger to cling unto the monster. This will open up either knife or weapon attacks, similar to when you mount on a monster on land.

You can use light or heavy knife attacks to create wounds or perform a big attack with your weapon while you are clinging on Lagiacrus. Just remember to dismount when Lagiacrus is about to do an attack to avoid getting damaged.

How to Use the Slinger

Grab Sharp Barnacle Clusters to Get Piercing Pods

Helix Piercing Pods
On the underwater walls, there are Sharp Barnacle Clusters that you can grab with your Slinger. This will give you Helix Piercing Pods which can be used to deal damage to Lagiacrus. Maximize your damage output by aiming these pods at Lagiacrus' head or rear while its body is straight. Pierce shots deal more damage the more times it goes through the monster's body.

List of Slinger Ammo

Drop Submerged Rubble on Lagiacrus

Submerged Rubble act as environmental traps underwater. Using your Slinger, trigger these traps when Lagiacrus is underneath them to deal massive damage to the monster!

How to Set and Activate Traps

Lagiacrus Attack Patterns

Moves labeled with a shield icon indicate that you can trigger a Power Clash with them. On the other hand, moves labeled with a sword icon indicate that you can counter them with an Offset Attack.
