Into The Depths Perks Guide: Best Perks & How to Unlock
Updated 2026-06-10

Introduction to Perks in Into The Depths
Perks are powerful passive bonuses that can dramatically change how you play Into The Depths. Unlike active abilities or equipment, perks provide permanent buffs to your colony, your explorers, or your resource production. Understanding the perk system is essential for surviving the deeper caverns and building a thriving underground settlement.
Each perk you unlock stays with you across runs, making them a core part of your progression. As you explore deeper levels, you will unlock perk slots and discover new perks that synergize with your playstyle. This guide covers every perk type, how to unlock them, and which combinations work best for different strategies.

How to Unlock Perks
Perks are unlocked through two main methods: progression milestones and special events. You do not need to purchase them with currency — they are earned by achieving specific goals.
Tip: Focus on completing early game objectives first. Many perks are tied to reaching certain depths or building specific structures.
Progression Milestones
- Reach depth 50: Unlocks your first perk slot.
- Build a Forge: Unlocks the "Smelter's Boon" perk.
- Survive your first raid: Unlocks "Defensive Stance".
- Collect 5000 gold: Unlocks "Greedy Hands".
Special Events
- Defeat a boss: Each boss drops a unique perk.
- Complete a challenge run: Rewards exclusive perks.
- Find hidden caverns: Some perks are only found in secret rooms.
Note: Perks unlocked during a run are permanent. You do not lose them when you restart.
Perk Categories and Best Choices
Perks in Into The Depths fall into three main categories: Colony, Explorer, and Combat. Each category supports a different aspect of your gameplay.
Colony Perks
These perks boost your settlement's efficiency and resource production.
| Perk Name | Effect | How to Unlock |
|---|---|---|
| Efficient Miner | +20% mining speed | Build 3 mines |
| Bountiful Harvest | +30% food production | Build a farm |
| Smelter's Boon | +15% metal output | Build a forge |
| Builder's Grace | -10% build time | Construct 10 buildings |
Best Colony Perk: Efficient Miner is widely considered the top pick because mining is the foundation of all progression. Faster mining means more resources, which leads to faster upgrades.
Explorer Perks
These perks enhance your ability to explore the depths and discover secrets.
| Perk Name | Effect | How to Unlock |
|---|---|---|
| Torchbearer | +2 vision range | Reach depth 100 |
| Cartographer | Reveals 10% more map | Find 5 secret rooms |
| Swift Feet | +15% movement speed | Travel 10,000 steps |
| Treasure Hunter | +20% loot from chests | Open 20 chests |
Best Explorer Perk: Treasure Hunter is excellent for mid-game when you need rare materials. Combine it with Cartographer to maximize loot.
Combat Perks
These perks improve your fighting capabilities against enemies and bosses.
| Perk Name | Effect | How to Unlock |
|---|---|---|
| Defensive Stance | +10% damage reduction | Survive a raid |
| Sharp Blades | +15% melee damage | Kill 50 enemies |
| Arcane Shield | +20% magic resistance | Defeat a magic boss |
| Adrenaline Rush | +10% attack speed when low health | Reach 10% health in battle |
Best Combat Perk: Defensive Stance is invaluable for surviving the deeper levels where enemy damage scales quickly. It provides consistent protection throughout your run.
Perk Synergies and Builds
Combining perks that complement each other can create powerful synergies. Here are two popular builds.
The Resource King Build
Focuses on maximizing colony output to snowball into late game.
- Efficient Miner + Bountiful Harvest + Smelter's Boon
- This trio boosts mining, food, and metal production simultaneously.
- Pair with Builder's Grace to construct buildings faster.
The Explorer's Fortune Build
Designed for players who want to discover every secret and collect maximum loot.
- Torchbearer + Cartographer + Treasure Hunter
- Increased vision and map reveal help you find hidden areas.
- Treasure Hunter ensures you get the best loot from every chest.
Warning: Avoid mixing too many combat perks with colony perks. You may end up being mediocre at both. Specialize in one area for better results.
Advanced Perk Strategies
Once you have unlocked multiple perk slots, you can experiment with advanced strategies.
- Stacking bonuses: Some perks stack multiplicatively. For example, multiple mining speed perks can drastically reduce mining time.
- Perk reset: You can reset your perk loadout between runs for a small cost. Use this to adapt to different challenges.
- Hidden perks: Some perks only appear after you have completed specific optional objectives. Explore thoroughly to find them all.
