Hollow Knight: Silksong

Alchemist's Assisant Walkthrough: All Plasmium Locations

Add to Watchlist

Hollow Knight Silksong Alchemist

The Alchemist's Assisant is a Gather Wish in Hollow Knight: Silksong. Read on to see a full walkthrough to completing the Alchemist's Assisant side quest, its objectives, and all plasmium locations.

How to Start Alchemist's Assisant

Talk to Alchemist Zylotol in Wormways

Alchemist Assistant Map

To trigger this quest, talk to Alchemist Zylotol in his lab, located on the top left area of the Wormways, on a somewhat unique section of the area. This place will be easily booked in your area with Bench Pins on as there is a Rest Bench in his lab.

Alchemist Assistant's Walkthrough

Quest Objectives

Find Three Plasmium Plants

Find the Plasmium Plants here!
Upper Wormways Near Bonegrave Path Lower Wormways

Upper Wormways

Map Location World View

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

Phial Usage

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

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!
