How to Beat Tisseur In Expedition 33

The Tisseur boss in Sirene is optional and carries the Anti-Charm

As soon as you engage in a fight with Tisseur, you end up cursed. This gives you fight turns to defeat them before you die. Hey, who doesn’t love a little bit of pressure with their fight?

While Tisseur does have a resistance to Ice, Earth, and Dark, it is weak against fire and light. It’s best to use those elements to fight. It doesn’t have a huge list of moves to use on you with curse being the biggest pain.

Slam is an attack that sees the boss slamming all characters at once. Dodge right after Tisseur’s arm start to swing towards you or parry before they come together in a slap.
Swipe Combo is a move that hits the party a total of four times. Jump accordingly when the commands hears on screen.
Glissando attack is a move where the Tissuer will call upon a Glissando. There’s an animation before it floats and then hits the ground.
Curse which will kill the entire party in eight turns. No way to avoid it sadly.

Rewards include chroma, XP, level 13 Tissenium, anti-charm pictos, 1 recoat, and 3 resplendent chroma catalyst.
