Where to find Antimass Substrate

Checked 2026-10-23. Patch context 2.0.2.

Antimass is the rock you spend in the Pattern Infuser. The item calls it a curious rock that underground Saxonite forms on. You start seeing it when Incursion unlocks at level 13, and high-threat jobs can drop it too.

When it entered the game

Patch 1.9 on 25 Jun 2026 added Incursion and Pattern Infusion. Player level 13 opens Incursion and the Antimass drip. The hub machine is the Pattern Infuser: you push one upgrade’s pattern into another, and removing more cells costs more. There is no official formula, so I will not print a flat price.

1.9.1 fixed a bug that ate Antimass without applying the infusion and refunded 30 to affected players. That refund is a patch note, not a farm.

A weekly claim I will not repeat as fact

A guide says the first weekly Overtime Assignment also pays Antimass. I have not verified the amount, so I am not putting a number on it.

2.0.2 adjusted Pattern Infusion again. If the machine’s preview disagrees with a June guide, trust the preview.
