Brimstone at Gallaman’s Tomb

Gallaman’s Tomb in the Desert, near the southern river and east of The Sentinels.

Before you go

Approach from the southern river side and find the cliff-side entrance to Gallaman’s Tomb.
Enter the first cavern cautiously and deal with crocodiles that block your path.
Search the first cavern for Brimstone deposits, then mine reachable nodes with your pick.
Continue into the second cavern only after checking your health, equipment, and remaining supplies.
Fight through any crocodiles in your way and inspect the second cavern for more Brimstone.
Stop gathering when your load or supplies call for a return; retrace the route through the two caverns you cleared.
At base, store the ore or use it in a current recipe that requires Brimstone, such as steel production.

Sinner’s Refuge is a nearby alternative Brimstone cave, but its defenders are hostile Exiles.
Check the recipes you intend to craft before the trip so you can set a practical collection goal; the haul can vary.

This is a repeatable resource run. Return when you need more Brimstone, accounting for the condition of the route and available deposits each visit.

Entering without a pick or enough inventory space; check your tools and carrying capacity before leaving base.
Treating the cave as one long passage; search and manage risk separately in its two caverns.
Pushing into the second cavern with low health or supplies; turn back while you can safely retrace your route.

Leave once you have enough Brimstone for your next planned batch, or earlier if your combat supplies or health make the return unsafe.
