Depths

In game

The game is one long descent. Each depth is a new cave, and the portal at its far end leads one depth down.

The caves

Each depth is a 128 × 128 tile cave generated from a seed. Clients rebuild it from that seed, so the map itself is never sent.
It holds about 77 packs of 4.7 monsters on average, kept away from the entrance.
The portal is guarded by a pack led by a guardian, a tougher rare (see Rarity).
When any living player steps into the portal, the whole party goes down to the next depth. Living players arrive with full life and mana.

Depth is level

Monsters are as many levels as the depth: each depth multiplies their life by 1.12, damage by 1.085 and experience by 1.1. Items that drop have an item level equal to the depth, which decides the bases, uniques and affix tiers they can roll.

What each depth unlocks

Only depths where something new appears are listed. Affix tiers are the higher tiers of an affix becoming possible on drops.
