Profitability and projections
The Wiki Estimate seeds loot and supply fields from current market inputs when available. Every assumption remains editable and your saved values take priority.
The calculator will update if the selected Wiki method provides a usable average loot value. You can enter your own value at any time.
Important drops
Notable rewards and drop categories
When the Wiki publishes a matching money-making method, its estimated average loot per kill is available in the editable calculator. Otherwise, enter your own verified sample.
What should I upgrade next?
Method-specific progression priorities
Dragon crossbow → Zaryte crossbow
Improve the primary damage role first; faster resolution leaves more attention for five phases.
Fortified Masori mask, body and chaps
Add the armour bonuses after the response to containment and cough is reliable.
Necklace of anguish
Consider this only after recorded Ancient Prison trips show the smaller gain is worth its purchase cost.
Common mistakes
Avoidable causes of failed or inefficient trips
Ignoring five phases
Losing position during containment and cough
Mishandling ice prison: React immediately when a teammate is trapped.
