On the following page of our Devil May Cry 5 Guide, you will find a description of the fight with the next boss in the game - Nidhoggh.
Nidhoggh in Devil May Cry 5
Where to find it: Mission 04 - V
The first boss you face as V. To reach the boss, you must first destroy its roots, which will try to attack you with charges. Use your minions, avoid attacks and finish the tentacles when their health is lowest.
When you destroy tentacles, Nidhogg appears, which you can attack directly. The enemy attacks you with blades and charges, but it's quite easy to avoid these attacks. Once all the tentacles have been destroyed, the enemy will be stunned for a moment and you will be able to take away some of his health.
The tactics are identical throughout the whole encounter. You have to destroy the tentacles and attack Nidhogg when he tries to attack you. At the end of the fight, you'll be fighting the boss and its tentacles at the same time, so you'll have to avoid a lot of blows. As a priority, destroy tentacles first - kill them quickly and summon Nightmare to strike enemies with strong area attacks.
