Massive Mossgrub Locations in Hollow Knight: Silksong

What to know

• Massive Moss Grubs are only found in the Memorium area of the Citadel.
• These Mossgrubs wander set paths and charge if you approach.
• They are bred artificially and described as nearly perfect forms with fur but still retain spines.
• Encounters are dangerous, dealing heavy damage if you get hit.

The Massive Moss Grub is a distinctive enemy in Hollow Knight: Silksong, notable for its enormous presence and aggressive behavior. Unlike standard Mossgrubs, the Massive variety has been bred within the confines of the Citadel’s Memorium, a location unique to Silksong. This is farmed as a part of Hunter's Journal.

How to locate and recognize Massive Mossgrub

You will only find Massive Moss Grubs within the Memorium of the Citadel. The Memorium itself is a late-game or advanced area, accessible after specific progression in Silksong.

Look for furred, spiny creatures much larger than regular Mossgrubs. There are no reports of these enemies being found outside Memorium, making them a unique challenge.

How to approach and defeat Massive Mossgrub

Step 1

Look for clear signs you have entered the Memorium—environmental details and enemy types change noticeably.

Step 2

Stay alert for their screech. This signals a coming charge attack, which covers significant ground and can catch you off guard.

Step 3

Use vertical movement and quick dodges to avoid their charge. Jump or dash away as soon as you hear the screech.

Step 4

Attack immediately after their charge, as they pause briefly to recover.

Step 5

Repeat careful dodging and timed attacks until the Massive Moss Grub is defeated. They have around 80 HP, so patience and strategy are essential.
