Gear gates the dark
The Shroud does not scale by time. It scales by what you can survive. Missing a tier of gear makes layers lethal fast.
The armor database shows the level bands you need before a deeper layer stops draining you to death.
Read the drain
If a layer drains you too fast, stop. Craft the resist buff and the right armor, then return with a real answer.
Boss order
Fight bosses in the order they unlock tiers. Skipping ahead wastes deaths you could avoid with a steadier climb.
Come back better
Each death teaches the missing piece. Note it, craft it, and the same layer becomes a routine on the next attempt.
The consumable database lists the buffs that ease the hardest layers once you own the gear.
