Atlas Threads
Last Update: 14/11/2026
Introduction
The new endgame Atlas shakeup completely changed the way you run your maps. You no longer have to get various Scarabs to add very specific modifiers to your Map. Instead, you simply broadly name how hard your Map should be on a scale of 1 to 8 by adding Threads. Each Thread adds a small chance for one of the few modifiers to occur; in some cases, multiple choices can overlap. It leads to a less deterministic experience, as the same amount of Threads may sometimes lead to a chill and comfortable Mapping experience, while other times cause havoc and destruction.
Of course, you will also want to boost specific mechanics with your Atlas Tree. Threads bonuses might seem insignificant at first glance, but make more sense once put in full context. Each Thread also enhances related mechanics with generic Monster Damage, Toughness, and Rarity bonuses.
You also can't forget about Mechanic Synergies. Those can occur only if they spawn close enough to each other, so the more you put them on your Map, the more often you will see them combine and evolve for even better results!
