Decision lab / run state matters

Good advice changes when the run changes.

This page is a hub rather than a second answer. Each question below is worked out on the page that owns it, so nothing here can drift away from the version boundary that page carries.

Guaranteed vs inferred

Read the layout without planning on a guess.

02 / Events

Choice conditions

Weigh Act, health, gold, deck, and party.

Shared vs personal

Scaling rules and the beta boundary.

04 / Patches

Input model

Every recommendation needs visible inputs

Scope

When this page helps, and when it does not

A good fit

You are choosing between options the game has already put in front of you: which node to take after seeing the map, whether an event offer is worth its price this run, what the boss on the current roster actually demands, or how a dated patch note changes a rule you had been following. In each case the page that owns the question works from visible inputs, and the table above lists those inputs so you can check your own run state before reading the answer.

Not a fit

This project does not produce unconditional tier claims, win-rate percentages, or a single best route that ignores run state. If the question needs a statistic the store data and the game cannot confirm, the honest answer is that the number is unresolved, and you will not find a substitute invented here. Advice written for the beta branch is also a poor fit for a default-branch run until it moves branches.

Reading the conclusions matters as much as finding them. Every conclusion here is a conditional statement: given these inputs, this choice tends to work out. If your run state differs from the listed inputs, the conclusion can differ too, and the correct move is to check which condition failed rather than to discard the page. Where a conclusion depends on a build, the page names the build, and the site-wide boundary is Beta Patch v0.111.0 (August 14, 2026).

Editorial boundary

This project will prefer a bounded answer over a confident guess. If a mechanic is branch-specific, the page will say so. If a statistic is a live observation, the page will timestamp it.
