Tower of Babel: Survivors of Chaos is NANOO's hand drawn survivors-like with Diablo style loot attached. It spent a year in Early Access from 19 May 2025 before the 1.0 build arrived on 26 May 2026 with five heroes. Every run climbs a numbered floor of the tower, and everything you pick up drops into a stash rather than onto your character.
This guide covers everything you need: core mechanics, the best builds, equipment worth investing in, location progression, and the tips that actually make a difference.
Core Mechanics
Auto attacking wave survival
Your character attacks on its own while you handle movement and dodging. Enemies pour in from every edge of the screen and drop XP shards when they die.
Three upgrade picks per level
Each level up offers three random choices from new skills, stat boosts and buffs to skills you already run. There is no reroll, so build plans have to bend around whatever appears.
Loot banks to the stash
Gear cannot be equipped during a run. Everything you collect goes into the stash for the next attempt, which means a failed run still leaves you richer than you started.
Runes, gems and sockets
Gear carries sockets that accept runes, gems and jewels, with an Alchemist handling the crafting side. This is where a build stops being generic and starts being yours.
Floor gated item levels
Every floor and difficulty combination has its own item level band, and Floor 1 on Normal drops item level 1 to 3 gear. Farming the right floor matters far more than farming for longer.
For a deeper dive into how these systems interact, see our Tower of Babel: Survivors of Chaos combat guide.

Equipment Guide
| Equipment | Why It Matters | Best For |
|---|---|---|
| Chain Lightning | Wizard staple that bounces between targets and clears rows of trash without needing you to reposition. | Wizard crowd control on dense floors |
| Ice Orb | Slow moving orb that applies Chill, cutting enemy movement and attack speed rather than just dealing damage. | Surviving packs that would otherwise close on you |
| Spear Spin | Skull Crusher's close range special. | Melee clearing while staying mobile |
| Blood Tornado | Warrior area skill that grinds through a group standing on top of you instead of pushing it away. | Holding the middle of a wave as a Warrior |
| Time Bomb | Demon Hunter's delayed explosive, designed to blow up a whole pack once the arrow volleys have bunched it together. | Clearing elites and dense clumps from range |
Chain Lightning: Wizard staple that bounces between targets and clears rows of trash without needing you to reposition.
Ice Orb: Slow moving orb that applies Chill, cutting enemy movement and attack speed rather than just dealing damage.
Spear Spin: Skull Crusher's close range special. At level 5 it deals 180 percent damage around you, adds 20 percent move speed during the spin and carries a 5 percent rupture chance.
Blood Tornado: Warrior area skill that grinds through a group standing on top of you instead of pushing it away.
Time Bomb: Demon Hunter's delayed explosive, designed to blow up a whole pack once the arrow volleys have bunched it together.

Location Progression
| Location | Level Range | Key Rewards |
|---|---|---|
| Floor 1 | Item level 1 to 3 on Normal | Starting gear and the first gold for camp upgrades |
| Floor 3 | Mid item levels on Normal | Better rarity rolls and your first meaningful runes |
| Floor 6: Hellblossom | Upper Normal item levels | Demon Hunter class unlock |
| Earlier floors on Hard | Hard difficulty item bands | Purple and orange rarity drops |
| The camp | Between every run | Permanent Strength, Dexterity and Intelligence that stack across all runs |
Floor 1: The opening floor, used to learn the auto attack loop and stock the first stash before anything gets dangerous.
Floor 3: Where the difficulty curve first bites and your level up picks start mattering more than raw stat totals.
Floor 6: Hellblossom: The floor that gates the Demon Hunter unlock, and the point where most players stall on their first serious push.
Earlier floors on Hard: Re-running cleared floors on Hard raises the item level band without the enemy density of an entirely new floor.
The camp: The hub between runs, where gold buys permanent stat upgrades and the stash gets sorted before the next attempt.

Tips That Actually Matter
- Read the floor header before you drop in. It lists difficulty, item level range, timer and reward modifiers, which tells you straight away whether this is a progression push or a farming trip.
- You cannot equip loot mid run, since everything goes to the stash. A run that ends in death still pays out as long as you were picking things up on the way.
- There is no reroll on level up. Take the three offers at face value and favour base attack damage, critical chance, attack speed and move speed early, because those work with any skill that shows up later.
- Chill from Ice Orb and Frost Nova cuts enemy movement and attack speed. On floors where you keep getting surrounded, a cold skill saves more runs than a damage skill.
- Skull Crusher's Berserk needs 35 successive kills and lasts 15 seconds for 15 percent more attack speed, attack range and cast speed. Route through trash constantly instead of chasing elites, because a break in the streak drops the buff.
- Camp gold buys permanent Strength, Dexterity and Intelligence that stack across every run and every class. Early gold is worth far more there than sitting in your pocket.
- Gear rarity runs Gray, Green, Blue, Purple and Orange, but do not vendor a Blue item with good sockets. Socket count and rune fit often beat a raw rarity upgrade.
- Spear Spin puts Skull Crusher inside the pack and drains mana quickly, so pair it with mana restoration on gear. Spear of Light covers the same class at range when the pack is too big to enter.
- Demon Hunter unlocks after clearing Floor 6, Hellblossom. If you want the arrow and bomb playstyle, push that floor with a Wizard or Warrior rather than grinding earlier floors for gear you will replace.
- Equipment changes your character's appearance on the following run, which is a quick visual confirmation that your stash swap actually applied before you commit to a floor.
Common Mistakes to Avoid
- Farming Floor 1 for hours. The Normal item level band there is capped at 1 to 3, so the time stops paying almost immediately.
- Ignoring basic attack stats in favour of flashy skills. Basic attacks are the consistent damage floor every build stands on.
- Skipping camp upgrades to save gold, when permanent Strength, Dexterity and Intelligence carry across every class you will ever play.
- Standing still to cast. The game auto attacks precisely so you can keep moving, and most deaths are positioning rather than a damage shortfall.
- Treating a failed run as wasted time. Loot banks to the stash no matter how the run ends.
