Dark Slugterra

Slugterra: Dark Dimension

Slugterra: Dark Dimension is an expansion for the original Legends of Slugterra mod, inspired by the Dark Slugs and Dark Energy featured in the animated series.

The original mod introduces the iconic slugs and their abilities. Dark Dimension adds their corrupted counterparts, a new dimension split into six caverns, the five legendary Elemental Slugs, a hostile clan that hunts you through Slugterra, a full corruption system and new challenges centered on the dark side of Slugterra.

This mod requires the original Slugterra mod to function.

🌑 The Dark Caverns

Travel through the Dark Portal into a dimension completely consumed by Dark Energy. Like the caverns of Slugterra, it is divided into 6 zones, each with its own terrain, fog, particles, ambient sounds and dominant Dark Slugs:

• Dark Water Caverns: crimson rock, shadow trees and glowing fungi.
• Ash Wastes: ash sand, scorched trees, basalt pillars and magma.
• Frozen Rift: slippery frozen stone, icicles and snow.
• Toxic Swamp: glowing toxic moss, dark lakes and luminous lichen.
• Shadow Forest: dense woods, hanging red vines and cobwebs.
• Spectral Crypt: soul soil, bone pillars and blue soul fire.

The zone’s name appears on screen when you enter it. The portal always finds a safe landing spot, so you won’t get stuck in the ceiling or inside blocks.

Dark Water flows through the caverns. It behaves just like normal water, but staying in it weakens you.

🐌 23 Dark Slugs

The expansion adds Dark versions of the slugs from the original mod, inspired by how they look in the animated series.

Each Dark Slug includes:

• A completely new model
• Custom textures
• Unique animations
• New visual effects
• More power than its normal counterpart
• Abilities enhanced and altered by Dark Energy

Wild Dark Slugs roam the Dark Caverns, and each zone has its own dominant species. Can you collect all 23?

⚫ Corruption System

Corruption is the core mechanic of this expansion. Using Dark Energy, normal slugs can be transformed into powerful Dark Slugs. Once corrupted, a slug:

• Becomes significantly stronger
• Takes on a corrupted appearance
• Gains altered abilities
• Becomes far more dangerous in combat

💉 The Dark Injector

The Dark Injector is a special device that can corrupt compatible slugs. Using it on a normal slug transforms it into its Dark counterpart, so you can build your own collection of Dark Slugs.

💚 Boon Doc

Boon Doc keeps its signature healing abilities. In this expansion it also purifies corrupted slugs and restores them to their original form. It is the only reliable way to reverse corruption.

🖤 Dark Boon Doc

Instead of healing, Dark Boon Doc uses Dark Energy to:

• Poison enemies
• Corrupt normal slugs into Dark Slugs

Boon Doc purifies, and Dark Boon Doc spreads corruption wherever it goes.

🔥💧🪨🌪️⚡ The Five Elemental Slugs

The legendary Fire, Water, Earth, Air and Energy Elementals are now in Slugterra. Only one of each exists per world.

• They appear one by one, over time, in the Slugterra caverns that match their element. Every player gets an announcement with their coordinates.
• They are far stronger than any normal slug, with high health and armor, regeneration and elemental immunities.
• Each one has its own proto form, velocimorph, capsule, impact effect, airborne ability (M key) and ground ability (Shift + right-click).
• Blessings: while you own a pure Elemental, you get permanent bonuses. Fire gives fire resistance and strength, Water gives water breathing and dolphin’s grace, Earth gives resistance and haste, Air gives speed, jump boost and no fall damage, and Energy gives regeneration, night vision and extra hearts.
• Lineage: each Elemental is the mother of several slug species. Corrupt an Elemental and its whole lineage turns evil across the entire world.
• Ghoul Elementals: a corrupted Elemental transforms into its Ghoul form. It gets a dark new look, its shots inflict Wither, and its hits curse enemies with the opposite of its blessing.
• The Energy Elemental can purify any evil slug. Its Ghoul form corrupts any slug it hits.

🐺 The Shadow Clan

Hostile packs of 3–5 Shadow Clan members now hunt in the darkness of Slugterra.

• They are long-range hunters. They keep their distance, circle around you and launch slugs from their scorpion-like tails.
• They run on all fours when chasing or fleeing, and stand upright to attack.
• Their howl stuns every player nearby.
• Attack one and the whole pack comes after you.

🏟️ The Shadow Arena

Giant colosseums are hidden in the caverns of Slugterra. They are the territory of the Shadow Clan.

• Step onto the combat floor to start the Arena Challenge: 3 waves of Shadow Clan members, ending with the powerful Alpha.
• Win to earn crimson crystals, diamonds, gold, slug cookies and experience.
• Shadow Clan packs are much more common around the arenas.

👤 Doctor Blakk

Doctor Blakk, the main boss of the expansion, waits deep within the Dark Caverns. He no longer appears on his own: you have to summon him with a forbidden ritual.

• Build the Doctor Blakk Altar structure with crimson brick, chiseled dark stone and crimson crystals, then activate it with a bucket of Dark Water.
• He makes an epic entrance as he rises from the altar, surrounded by soul flames and lightning.
• He has a custom boss bar with 3 combat phases.
• He keeps his distance and fires Dark Slugs faster and faster as the fight goes on. If you get too close, he punches you away.

🔫 Dark Blaster

The Dark Blaster cannot be crafted. The only way to get it is to defeat Doctor Blakk, and it lets you wield the full power of Dark Slugs.

🥋 Slug-Fu

Slugs now fly slower and stay in the air longer the higher their level, from 8 seconds at level 1 up to 60 seconds at level 20. Press G to use Slug-Fu:

• Guided mode: the slug turns toward wherever you aim.
• Full control (level 20/20): the camera moves to the slug’s eyes and you steer it until it hits.

Slug-Fu works with both normal and Dark Slugs.

🌾 Luminous Wheat & Slug Cookies

Find Luminous Wheat seeds in grass and grow a glowing crop. Bake Slug Cookies and feed them to your slugs to raise their combat and trust experience.

🧱 New Blocks

The expansion adds dark stone bricks, chiseled dark stone, crimson bricks, glowing crimson crystal, shadow and toxic moss, frozen dark stone, ash sand, shadow and scorched wood, glowing mushrooms and more.

🏆 Achievements

A full achievement tab, “Dark Slugterra”, covers your journey from your first step through the portal to defeating Doctor Blakk, collecting every Dark Slug and taming all five Elementals.
