Скачать или смотреть Code Vein Boss guide (2025) - Butterfly of Delirium

Hi there people! I'm making this to help people have a better time with the bosses.

The Butterfly of Delirium is weak to fire and slash, so these are what you should focus on, though the other resistances are quite low, so you can use whatever you prefer. Melee is the best option here, as outside fire, the other elemental resistances are a bit higher.

As for status effects, it's immune to most of them except for slow, so I wouldn't recommend using status effects on this fight.

For fire you have 2 good options. Flame Spike comes from the Hunter blood code and is the one that deals more damage due to a higher multiplier, while Fire Storm comes from Prometheus blood code and deals a bit less damage while costing a bit more ichor, but in theory does more stagger. Personally I prefer the Flame Spike due to higher damage and lower cost, but you can use whatever suits you best.

You get Flame Weapon once you go down the elevator after the fight with the Butterfly of Delirium and reach Dried-up Trenches. This means that you won't have it for the fight on the "campaign", but you can use it when you face it in the depths. It's a damage boost, but not too great, so it's not mandatory.

A blood veil with high venom resistance is quite important, but due to how common the tail swipes are, a blood veil that you are used to for parrying is a good option. Each type of blood veil has a different parry start-up and duration. If you want a video on that, let me know and I'll make it.

Thank you for reading and watching.
