Delverium Quartz Crystal: Where to Mine and Craft Quartz Torches

Updated October 4, 2026 · Delverium Guide

Quartz Crystal is recorded from Quartz Crystals and Raw Crystal Walls in the Crystal Cavern. One Quartz Crystal plus one Hardwood crafts three Quartz Torches at a Hardwood Workbench. The official v0.1.0.3 update assigns Quartz Torches 50% base spawn suppression.

Collect Quartz in the Crystal Cavern

Look for the named crystal objects or Raw Crystal Walls in that region, harvest them with the appropriate resource tool and check the Quartz Crystal stack. Opal and coloured crystals are separate materials; do not assume a coloured-crystal recipe consumes Quartz interchangeably.

Make the torch batch

Check the station as well as the ingredients. Ordinary Wood and a basic Workbench do not match the row above. Reserve Quartz for other uses if you also plan the Jeweled Hammer recipe.

Use the current suppression rules

v0.1.0.3 lists Standard Torches at 25%, Quartz at 50% and coloured crystal torches at 75%, with a six-tile range and biome modifiers. Follow the full suppression table for those modifiers. Suppression affects new nearby spawn attempts; it does not erase enemies already present or every summoned enemy.

These figures do not establish additive stacking from overlapping torches. Place lighting to cover the space you actually use and distinguish continued arrivals from a failed new-spawn suppression effect.
