Tartarus sets the tone
The first biome is where the game teaches its rules. The rooms are simple, but the discipline carries into later areas.
Most early deaths are self-inflicted. Slow down, read the room, and the biome stops feeling like a wall.
Room order
Clear the ranged foes first so they stop sniping while you chase melee. Then collapse on the survivors together.
Use the environment: falling rocks and spikes kill as well as your blade. Let the room do part of the work.
The boss gate
The biome ends in a boss that tests your dash. If you reach it low, spend a defiance to learn the pattern.
Clearing Tartarus is half the mental battle. The boss strategies page prepares you for what waits at the gate.
Next: Pact of Punishment.
