Ignoring the timer
New players loot until the Shroud empties them. Watch the bar and leave with time to spare before the drain wins.
The consumable database holds the buffs that buy those extra seconds you keep wasting.
Mismatched armor
Wearing the wrong class throws away your bonuses. Check the armor database before a dive into a new layer.
Hoarding junk
A pack full of the wrong potion is dead weight. Carry what the next fight needs, not every item you stumbled across.
No base
Sleeping in the open invites death. A small walled base at the flame altar changes everything about your early survival.
Each mistake above is a quick fix once you plan the run instead of charging in blind and paying for it.
