SULFUR guide
Oils, scroll combinations, weapons, cooking recipes, bosses and achievements for SULFUR 1.0.
Checked against patch 1.0.6, released 9 November 2026.
Build a gunFive complete rank-5 setups for 1.0: a Holy Fire Fisk for bosses, an explosive 12Ga for crowds, a D4RT that never uses ammo.
Beat a bossEach boss takes damage in one place, from the Cousin's mud to Terrorbaum's eye. Since 1.0 damage gates stop one-shot kills.
Oil a gunOne oil per rank, five at rank 5, never two copies. Each oil adds 1 durability per shot unless its card says it does not.
Add or mix scrollsA gun holds one scroll, even with free slots. Kevin the Scholar merges two Stage 1 scrolls into a Stage 2.
Keep loot after deathOn Hard you lose everything you carry. Church storage and Stamps stay; Insurance returns one weapon.
Use a Crypt KeyOpens a Desert Trial of the Spirit: survive two minutes for a passive item. Failing kills you, so carry a charged Amulet.
Rank up a gunXP comes from damage; rank 5 takes 3,224 XP. Since 1.0 a kill's XP is split between the guns that hit.
Cook to healA combination that is a recipe is saved permanently. Search the recipe list by the ingredient you hold.

Rules worth knowing before a run
- What you lose when you die in SULFUR: difficulty, Insurance and pityOn the default Hard difficulty you lose everything you carry. Very Easy keeps it all, Easy loses money, Medium loses unequipped loot. Insurance returns one weapon; the Collection Box pays back 10%.
- SULFUR boss guide: how to beat every boss in 1.0Where each SULFUR boss can be hurt and what kills you: Cousin's mud armor, the Cardinals' beams, the Novanian Guard's helmet, Lucia's eye, Terrorbaum's returned bullets, the Emperor's tail and Desert Claus.
SULFUR scrolls: how to combine them and what each element doesCombine two Stage 1 scrolls in Kevin's Mixing Magics grid to make a Stage 2 scroll. A gun holds one scroll, every scroll costs 1 extra durability per shot, and some multiply that cost.- SULFUR weapon ranks: XP, fast levelling and Telia's ReplicatorRank 5 takes 3,224 XP and opens five enchantment slots. In 1.0, XP is split equally between guns used in a kill and melee kills feed your selected gun. Lock of the Magus multiplies one kill by 100.
- SULFUR Stamps: how to get them and which Church upgrades to buyStamps come from NPC turn-in quests and are never lost on death. Spend them at Arthur: Baptismal Font (10) and storage first, Delivery Demon (35) and Holoreality Projector (50) for shop access.
