1. Invasive Battle Clues 2. Get Anti-Paralysis For the Whole Team 3. Use Speed Double Attacks 4. Stop Khezu After it Uses “Learning Complete” |
Invasive Battle Clues
| Clue | |
|---|---|
| 1. | If it's coming at us with sheer power, we should outmaneuver it with speed. |
| 2. | One of those hits would be the end of us. We'd better prevent it from attacking. Prevent it from attacking, you say... Ah! Try syncing your breathing with your Monstie!. |
| 3. | Looks like it uses electric attacks. Make sure you're ready to deal with paralysis. |
Use Nargacuga's Stealth Skill to Collect Clues
To collect the Invasive Monster Tracks and remain unseen by the Invasive Monster, players can ride a Nargacuga and use its Stealth Skill by pressing the the roar button. The Invasive Monster will now not be alerted as long as stealth is active.
Note however that players can only get a Nargacuga by beating Invasive Nerscylla.
Get Anti-Paralysis For the Whole Team
The pre-requisite of the fight is to have the means of providing Paralysis Resistance to the whole team. This can be done through multiple ways such as items, genes, or decorations, but our recommended way is to use a Hunting Horn with the Bolstering Ballad skill!
Use Power Double Attacks
The first prerequisite to repelling the Invasive Khezu is by utilizing double attacks. It will use a technical attack at the beginning, so win using double power attacks.
Stop Khezu After it Uses “Learning Complete”
Once Invasive Khezu uses Learning Complete, you'll get a warning from your team that it is paramount to stop it from attacking. The guaranteed way to do that is to use Kinship Skills!
This will prevent its next action and your Kinship gauge can be easily filled up with the double attacks from the earlier turns. If you are having trouble building it up, consider using the Egg Skill: Solar Cry.

Invasive Khezu Attack Patterns and Behavior
Attack Behavior
| Normal |  |
|---|---|
| Invading |  |
| Enraged | |
Normal State
| Turn | Skills Used |
|---|---|
| 1 | Thunder Fang |
| 2 | Thunder Zone (applies Paralysis) Shift to the Invading State |
In its Normal State, the Invasive Khezu will release two types of attacks. The first, Thunder Fang, is a Technical Attack while its second, Thunder Zone is an AoE Thunder type attack that inflicts paralysis.
The paralysis ailment plays an important role for its Wyvern Charge as it shifts to its next state, the Invading State.
Invading State
| Turn | Skills Used |
|---|---|
| 1 | Power Attack |
| 2 | Wheeze (Non-damaging) Will shift to the Normal State. |
| 3 |  Wyvernsoul Eater (Negate Ailments) Wyvernsoul Eater (Negate Ailments) Wyvernsoul Eater (Negate Ailments)
|
| - | Wyvern Charge Complete |
| 4 | Invasive Death Voice (Powerful Single Target Attack) Will shift to the Normal or Enraged State |
The Invasive Khezu in its Invading State will primarily release Power Attacks. However, its Wyvernsoul Eater skill rotates between attack types (Speed then Technical then Power). This skill also negates ailments applied to the boss.
After the head to head, the Invasive Khezu will complete its Wyvern Charge, which will not take up an additional turn. In its last turn, it will release Invasive Death Voice, a strong single target attack.
Enraged State
| Turn | Skills Used |
|---|---|
| 1 | Thunder Trap (AoE, Applies Shock) |
| 2 | Bolt Eater (Single Target, Slight Healing) |
| 3 | Bolt Eater (Single Target, Slight Healing) |
Players can tell when the Invasive Khezu is in the Enraged State, when it has red energy around its mouth. During this state, the boss will inflict Thunder Trap, an AoE skill that applies the Shock status. This status deals damage to the inflicted at the end of each turn.
The Invasive Khezu will also use Bolt Eater, a single target move that restores a small amount of HP to itself.
How to Beat Invasive Khezu
Level Up to at Least 72
The Invasive Khezu will be at level 75 when fought so make sure to level up your party to at least Level 72.
EXP Guide: How to Level Up Fast
Bring Fire and Debuff Focused Monsties
 Espinas
|
 Brute Tigrex
|
Espinas makes for a top choice due to its high stats and Fire element advantage against the boss. Additionally, it can also apply Paralysis with Infernal Flames.
The Brute Tigrex also makes for a good pick due to also having high stats as well as being able to apply the Defense Down debuff.
Bring a Hunting Horn With Bolstering Ballad
A very important tip to remember for this fight is to bring a Hunting Horn with Bolstering Ballad to protect your party against Paralysis during skills like Thunder Zone. This Paralysis allows the Invasive Khezu to complete its Wyvern Charge so stop it with hunting horns that can use the weapon skill like the Spirit Dragonwood Horn.
Use Double Head to Heads
Players should aim to use double attacks during head to heads against the Invasive Khezu to interrupt its Wyvern Charge. This happens primarily during its Invasive State so employ double attacks to cancel its skill damage during the turn.
How to Use Double Attacks
Invite Kora with Gravy
Kora makes for a great ally during this fight because the Invasive Khezu will mostly use single target attacks. Kora will be able divert the attacks to herself.
Additionally, invite her Monstie Gravy as it can use the skill Bishaten Embers which prolongs the duration of debuffs.
List of All Characters and Companions
Equip Thunder Resistant Armor and Genes
The boss will primarily use strong Thunder Element skills so equip your protagonist with Thunder Resistant armor. In the same vein, transfer Thunder Resistant genes to your Monsties to decrease the damage from these attacks.
Bring Fire Weapons
The Invasive Khezu will be very weak to Fire elemental skills. Equip your protagonist with the corresponding weapons to take advantage of this elemental weakness.
Inflict Paralysis
Paralysis is the only ailment that the Ivasive Khezu has a weakness to so use it to your advantage and apply it through Monstie or Weapon Skills. Having it paralyzed will also increase the chances of stopping the boss' attack within the turn.
Rewards for Repelling Invasive Khezu
Obtain a Barioth Egg
The main reward for repelling the Invasive Khezu is an endangered Barioth egg. This will let you repopulate the map with Barioths and hunt them for Barioth equipment or obtain more Barioth eggs!
Two Decorations After Slaying
The first time you slay Invasive Seregios inside of its invasive den, you will be rewarded two weapon decorations, True Wide Slash (BST) and Aerial Aim (WYV).
List of All Decorations and Equipment Skills
Invasive Materials
You will also get invasive materials, like the Invasive Claw that you can use to max out the level of your equipment.
