In Demon Born , you get Insect Breathing by reaching level 10, then going to the eastern tatami training hall and completing the Insect-style trainer minigames before the quest’s fight phases. The guide also says Insect Breathing is unlocked through its own quest track, so you generally need to finish that path on your character rather than mixing it with another breathing quest.

Quick steps

  • Reach level 10 first.
  • Go to the east side of the map, at the tatami training hall.
  • Talk to the insect-style NPCs and clear the indoor minigames.
  • Finish the follow-up boss-style encounter to unlock the breathing.

What helps

  • The guide says Insect Breathing is strongest for poison damage over time, so it shines against tanky bosses.
  • It also notes that the quest line uses trainer minigames first, then a Hashira-tier fight pattern.

One important note

A lot of older videos and pages about “Insect Breathing” are for Demon Fall , which is a different game, so don’t mix those requirements with Demon Born.

If you want, I can also turn this into a clean Roblox-style walkthrough with the exact route and quest order.
