Match the level
Each dungeon has a recommended level. Enter too low and the enemies outclass you; enter too high and you waste a safe run.
Short before long
Clear short dungeons to build gold and trinkets, then attempt the long ones with a prepared party.
Know the exit
Before pushing deep, confirm you can retreat. A planned exit beats a desperate one when the party breaks.
Loot the right wing
Some wings hold the trinkets you need. Target them instead of clearing every room.
Scout the length
Longer delves need more torches and food. Pack for the distance before you step in.
Read the roster
The enemy database tells you what waits inside. Match the party to the classes listed.
Pace the halls
Fight in doorways where only one foe reaches you. A narrow chokepoint is worth more than a wide room.
Leave loot behind
A full pack slows the retreat. Carry what matters and run when the party is spent.
