Upper Wormways

Located right below Zylotol's lab, part of the upper network of canals in the Upper Wormways, located in a cave-in with the glowing blue Plasmium at the end.
Near Bonegrave Path
| Map Location | World View |
|---|---|
 |
 |
This Plasmium is located near the end of the Wormways, towards the Bonegrave Path, on a green trail where the Plasmium glows at the end as well.
Lower Wormways
| Map Location | World View |
|---|---|
 |
 |
Located at the very deep end of the Lower Wormways, reaching this part requires some skilled timing to avoid the worms blocking the path downwards and the spikes blocking the way. The Plasmium is located at the very lowest part of the area, on a small cavern.
Charge and Use Needle Phial To Collect Plasmium
Zylotol will give you a temporary tool, the Needle Phial, to extract the flowers as he instructed. Approach the Plasmium Plant and charge your Needle Phial before hitting it to collect the material.
Once all Plasmium Plants are collected, you can go back to Zylotol to finish the quest and receive a Plasmium Phial for your trouble.
Alchemist's Assisant Rewards
Plasmium Phial
You will get several shots of Plasmium Phial from Zylotol as a reward for the quest, with an extra 20 in reserve. Plasmium Phial has similar effects to Lifeblood Masks from the original Hollow Knight, providing extra non-regenerating health to Hornet.
You can have these refilled in exchange for Rosaries if you want to return to Zylotol. The concoction can also be mixed with other Tools to provide different effects when used!
