How to Beat Ruiner Nergigante

New Dive Bomb Follow Up

How to Beat - Ruiner Nergigante 1.gif
After dealing enough damage to Ruiner Nergigante, it will eventually use its most powerful attack where it jumps and then dives forward releasing the spikes surrounding its body. This move can also be seen in the normal variant of Nergigante. However, for the Ruiner Nergigante, a handful of spikes will shoot forward hitting hunters who are trying to dodge.

Avoiding Damage

You can easily dodge this attack if you run towards the rear end of Ruiner Nergigante after roaring. This will get you out of range of the follow-up attack and the Dive Bomb.

Short Jumps

How to Beat - Ruiner Nergigante 2.gif
Be wary of Ruiner Nergigante's quick short jumps whenever it tries to reposition itself. Your window time to avoid this move is extremely short. It is recommended that you equip the skill Evade Window.

Predicting the Attack

The thorns that will shoot out of its body can easily be predicted if you keep track of which side Ruiner Nergigante's spike is in white. Ruiner Nergigante will only shoot spikes from this side. Always prepare to dodge after attacking to avoid taking damage.

Aiming for the Metal Spikes

How to Beat - Ruiner Nergigante 3.png
During the fight, Ruiner Nergigante will always have metal spikes that can easily be distinguished. These spikes are special spikes that are a bit harder to break and unlike other spikes, these metal spikes will not regrow for the rest of the fight. Breaking these spikes will make Ruiner Nergigante's attacks weaker and it will also lessen the spikes that will fly out from its attacks.

Ruiner Nergigante's Sides

How to Beat - Ruiner Nergigante 4.png
Ruiner Nergigante's side attacks are easier to predict and can be weakened if you break the white spikes on its arms. Most of Ruiner Nergigante's attacks strike forward. It is recommended that you stay on its sides as much as you can. This will give you more opportunity to attack its weak arm.

Attacking the White Spikes

Prioritizing the White Spikes

The Ruinder Nergigante has white spikes that you can try to focus down during the fight which are easier to break. Try to break them as soon the fight starts and whenever they respawn on Ruiner Nergigante's arms. You can use clutch claws to position yourself better to focus on attacking them without any problems.

Remove Bleeding

It is recommended that you carry an Astera Jerky for this fight. Some of Ruiner Nergigante's attacks can inflict bleeding which can be a huge problem if the fight is going to take long. You can get bleeding if you get hit by the metal spikes on some areas of Ruiner Nergigante.

Taking Your Time

Whenever Ruiner Nergigante takes you down, do not stand up immediately. Nergigante's attacks usually have a follow-up that can deal additional damage to you. Keep this in mind and try to stay down until you know it is safe to get up and the Nergigante's combo is finished.
