The Deep Immersifier in Honkai: Star Rail is a special consumable that lets you get Planar Ornaments without spending Trailblaze Power or running full combat stages, so you should save it for high‑value extractions rather than casual farming.
What Deep Immersifier does
- It is a rare “energy substitute” item used specifically for Planar Ornament extraction in the Interastral Peace Guide.
- When used, it lets you extract Planar Ornaments (typically higher‑difficulty ones) without consuming 40 Trailblaze Power like a normal Immersifier would.
How to use it (step by step)
- Open the Interastral Peace Guide and go to the section related to Planar Ornaments / Ornament Extraction (end‑game modes like Simulated Universe/Divergent Universe, depending on your version).
- Start or access a Planar Ornament extraction node (e.g., after a boss/elite floor or via the “Ornament Extraction” menu, depending on mode).
- When the game asks how to pay for the reward, choose to consume 1 Deep Immersifier instead of 40 Trailblaze Power.
- Confirm; you instantly receive a Planar Ornament reward, with rarity depending on the difficulty you’re running (Deep Immersifier does not boost drop rates, it just replaces the energy cost).
When you should use it
- Use it only on the highest difficulty Planar Ornament content you can reliably clear (e.g., Difficulty V or your maximum unlocked), so the free extraction has the best possible loot table.
- Prioritize using it during events that boost Planar Ornament rewards (like Planar Fissure‑type events), since you get more value per Deep Immersifier in those windows.
- Since it is obtained in limited quantities (such as weekly point rewards from the “Currency Wars: Zero Sum Game” mode), treat it as a premium resource and avoid spending it on low‑tier or experimental runs.
If you tell which world/difficulty you’re currently farming, a more tailored “use it here” recommendation can be given.
