SULFUR Game Guide

Quick Answer

Enter Caves left of the Church, recharge your amulet on Floor 4, and reach Cousin on Floor 7. Floor 5 has an armored goblin miniboss; explosives open cracked-wall secrets along the way. Defeating Cousin unlocks Town, and a wooden cargo elevator returns you to the Church.

What route takes you through all seven floors?

You progress through seven floors, with fixed milestones on Floors 4, 5, and 7. Use these milestones to track your progress rather than expecting a room-by-room route. Detailed room routes and hidden entrance locations are still being expanded.

1–3Explore the opening floors, gather supplies, and continue toward the Floor 4 altar.

6Continue toward the final floor and Cousin.
7Defeat Cousin, unlock Town, and take the wooden cargo elevator back to the Church.

Enter from the Church

Take the cave entrance on the Church's left side. Caves is your starting dungeon, with Goblins and Elite variants making up most encounters. Some rooms also contain Black Guild enemies, including Guard Dog and Tracker.

Reach the Floor 4 altar

Continue through the opening floors until you reach the amulet checkpoint on Floor 4. Recharge there before continuing deeper. The amulet guide explains the item you refill at this altar.

Clear Floor 5, then reach Floor 7

Defeat the Floor 5 miniboss before continuing through Floor 6 toward Cousin. Collect the miniboss reward: a Scroll or Oil. The final arena is on Floor 7, rather than immediately after the miniboss.

How do you beat the Floor 5 miniboss?

Break the miniboss's wooden armor, jump its shockwaves, and finish its smaller forms one at a time. This encounter is the Matryoshka Monstrosity Goblin Barrel Boy fight.

Jump over the landing shockwave

The large armored goblin frequently jumps and creates a ground-level shockwave when it lands. Jump over the wave as it reaches you.

Break the wooden armor

Attack the protective wooden pieces until they break. Once exposed, the goblin can take direct damage.

Finish each smaller goblin

After enough damage, the miniboss splits into three smaller armored goblins. Choose one, break its armor, and finish it before switching targets. This reduces the number of enemies attacking together. After winning, collect the Scroll or Oil reward.

Where are the cracked-wall secrets and useful supplies?

Use a grenade or another explosive on walls marked by a large crack to reveal hidden loot rooms. These rooms contain a loot container, Oil, or Scroll. Some cracked-wall secrets also hide a toilet giving access to item storage. See the toilet room guide when you find one.

What you findWhat you can collect or do
Large cracked wallBreak it with explosives to access the room behind it.
MushroomsGather them throughout Caves.
Wooden barrels and barricadesBreak them for a chance of Stick drops.
StalagmitesBreak them for rare Rock drops.
Food suppliesLook for Bread, Butter, Potato, Cheese, Bottled Water, Broth, and Snail.
Groups of explosive barrelsLook between them for Dynamite or Stick Grenade.
High or difficult ledgesSome hidden areas and chests require increased jumping power or an extra jump.
WaterLoot containers can appear underwater.

You can find chests in difficult positions, so check more than the obvious walking route. However, underwater loot does not guarantee a specific weapon.

What dangers should you watch for?

Watch your footing on narrow bridges and cliff ledges, because falls can seriously injure or kill you. Large rooms and high ceilings do not make the ledges safe. Low health makes a fall especially dangerous.

Do not assume every visible chest has a safe approach. Some require better jumping, and underwater exploration carries a drowning risk.

Expect Goblins beyond basic melee enemies, including Goblin Archer and elemental Goblin Wizard variants. Black Guild enemies can also appear in certain rooms. Watch for Guard Dog and Tracker rather than assuming every encounter follows the same goblin pattern.

How do you reach and defeat Cousin?

Reach Floor 7, then approach the bubbling mud pool in the three-pool arena to summon Cousin.

Cousin rises from the mud pool when you approach it.

Break the mud armor

Cousin throws mud projectiles, so keep moving while you attack. Shoot away the mud armor before trying to damage the body underneath. When Cousin returns from a pool, remove part of the renewed armor before expecting body damage.

Track the pools and reinforcements

After taking damage, Cousin dives into mud and resurfaces from a random pool. The first disappearance can come around 75% health. Avoid staying beside a single pool while waiting for the return.

At roughly 50% health, expect Goblin Spearman and Goblin Young reinforcements. The later wave arrives around 25% or 15% health, depending on the account. Be ready throughout that final quarter.

Finish the fight and leave

Penetration effects, especially Holy Fire, work well against Cousin. Use the Cousin boss guide for more detail on the fight and possible rewards. After winning, Town unlocks and the wooden cargo elevator takes you back to the Church.
