How to beat the Roaring Knight secret boss fight in Deltarune Chapter 3

In Deltarune Chapter 3, the secret boss, the Roaring Knight, takes one of the most brutal tests of players yet. The tough challenge appears near the chapter’s climax after the Teena boss fight.

Here, the formidable foe can decimate the unprepared players, ending the fight in just seconds. This is why moving ahead with proper strategy, sharp reflexes, and the right gear is quite important. Do not expect a fair fight without the right tactics and tools. Here is how to defeat Roaring Knight, and claim victory with rewards.

Prepare to master Roaring Knight fight

Forget winning over the Roaring Knight without a Shadow Mantle armor—essential armor that helps to reduce the incoming damage.

Ensure to equip it on the Susie (high attack power and HP) right before you trigger an encounter that starts after Teena boss fight. Meanwhile, Ralsei and Kris can focus on the support by using the buffs and healing items.

Note: To get the Shadow Mantle armor, you must have achieved S Rank in the Board sections (both) of Chapter 3 apart from completing a series of mini-games and defeating the mini-boss of Shadow Mantle.The Knight will unleash relentless attacks, demanding your perfect reactions.

The basic slash is quite manageable, too, as it's slow and easily avoidable; just dodge sideways. Ice Crystal Barrage (low but fast damage), though, needs diagonal dodging between the projectiles. Just ensure to be sharp.

The real threats in the fight are the devastating special moves of the Knight. Gaster Sword Blasters can give a near-instant death if you mistime the dodge. So, anticipate it. Lemonbread Slash, on the other hand, hits quite fast and hard.

It leaves very little room for any error—block if it's possible. The worst remains the Sworrd’s Dance. Consider it to be an almost (not completely) impossible attack that cannot be dodged.

So, plan healing beforehand. The singular goal at the end must be to deal damage that’s equivalent to 25% of the massive health pool.

Kris, on the other hand, must balance the attacks with the right item use or even healing when Ralsei gets overwhelmed. The priority of Ralsei is to keep all alive, especially after the heavy hits by the Roaring Knight.
