Tinkerlands: All Bosses Guide

The Slimeking is the first boss players usually encounter in Tinkerlands. It appears randomly in the Grasslands biome, often preceded by the message: “You feel like something is coming from afar…”.

Alternatively, it can be summoned by using a Slime Voodoo Doll, which is crafted at a Working Table using 50 Mucus. The doll also has a chance to drop from regular Slimes.

The Frog Prince is encountered in the Swamp biome, where it can be summoned by placing 5 Eye of Newt on its altar. Interacting with the altar while carrying the required items will automatically place them and spawn the boss.

After the Frog Prince is defeated, the altar temporarily disappears but will respawn, allowing future summons.

The Mineral Spider resides in the center of the Caves, accessible through an entrance located in the Snow Biome. At the boss area, players will find The Carpenter, who is wrapped in silk strings. Interacting with him will trigger the boss fight.

Alternatively, the boss can be summoned using a Mineral Spider Egg, which is crafted at a Working Table with 50 Mineral Silk.

The Iron Devourer is a late-game boss that can be summoned by placing the four biome-specific items known as Thumpers. These include:

• Thumper (Forest)

• Thumper (Desert)

• Thumper (Snow)

• Thumper (Swamp)

Each Thumper must be placed on a tile corresponding to its respective biome type. Once all four are correctly placed, they will be removed from the world and the Iron Devourer will spawn at the center of the ritual area.

The Overgrown Crab is a late-game boss that does not spawn naturally. It can only be summoned using Crab Juice, which is dropped by rare blue crabs found in the Beach biome.

Drops

The Grim Reaper is a boss that can only be summoned using a Cursed Doll. This item is crafted by Skeleton, an NPC who can be found in the Pumpkin Biome within the Caves, using 20 Dolls and 20 Needles.
