Invasive Diablos is found on the Colossal Dragon's Remains area which is found on the southmost part of Tarkuan.
| Clue | |
|---|---|
| 1. | Landing an attack would be quite the ordeal. Can we discern any exploitable patterns? |
| 2. | Hm... If we what it from above as it shoots up from below, it's sure to get quite the shock! |
| 3. | Nothing pounds like a hammer! For a vertical strike, perhaps that technique would do... |
The clues related to Invasive Diablos involves a hammer weapon and a strong strike from above.

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.
The technique needed is the Meteor Strike skill. This is a hammer skill which is needed to progress the quest. You'll be able to learn about the skill requirement during battle where Rudy hints with a meteor skill.
Once the Invasive Diablos burrows, you'll see the ground create mini earthquakes. Time your Meteor Strike use on the ground to be able to hit the puzzle's prerequisite requirement.

The reward for repelling the Invasive Diablos is a Tigrex Egg. This lets you use Habitat Restoration to be able to hunt more Tigrex and obtain more eggs in the game.
