How to Beat the Knight Boss

How to Beat the Knight Boss General Tips
Do not disturb the webs Make sure to topple all controlled suits of armor Look out for shadows of falling debris If you only topple 1 enemy, the other enemy will reassemble the fallen

Phase 1

Try to geth both suits of armor on the same rug. Time your A-Pull to pull the rug under both of the ghosts. When both suits of armor fall down, the Tough Possessor will appear.

Dodge its initial charge attack so that it hits a wall and stuns itself. Try not to disturb the webs in the battle field. These webs are what prevent mice from spawning into the room.

Flash it with the Strobulb then latch onto it with the Poltergust to peel back and capture its first layer. Once it recovers, it will take control of three suits of armor starting the second phase of the battle.

Phase 2

Use the same strategy of luring the suits of armor on a rug then pulling the rug under them. During this second phase, the Tough Possessor will use two energy orbs to amplify its charge attack.

All you need to do is dodge, then use the orbs as a guide to know when it is safe to approach the Tough Possesso. Flash it again and latch on to peel back the second layer. Afterwards, a short cutscene will play out, then the Tough Possessor will have a new form — a giant suit of armor!

Phase 3

In this phase, the Tough Possessor has a different attack set. This giant suit of armor is capable of wide stomp attacks and sword attacks. Because of its size, you can expect that debris will fall on the battlefield. Evade the shadows as they show where the debris will fall.

Get the giant suit of armor on one of the rugs and perform a fully charged A-Pull to topple it. Afterwards, evade the Tough Possessor's charge attack and three energy orbs. Once it is stunned, capture its final layer to get the final Dark Moon Piece.
