Decision Matrix
Choose the right lane
Use this as a quick navigation board: scan each fight or build decision, then jump to the full breakdown and source frames below.
Rarity is only one layer
Common, Rare, Epic, and Heroic describe strength scaling, but they do not explain whether a boon is allowed to appear. Legendary and Duo boons are special because they require the run to satisfy prerequisite logic first. A player who only rerolls for a shiny result without meeting that logic is not unlucky; the target may not be in the pool yet.
Prerequisite planning
Before chasing a Duo, identify the two gods and the specific core boons that unlock it. This is why god keepsakes matter: they do not only raise odds, they control the order in which your build becomes possible. The first biome should usually secure a core god, while later biomes refine the pool and look for the payoff.
Reroll discipline
Rerolls are strongest after the run has satisfied a requirement and weakest when used to repair a confused build. If the offered god does not advance the target, sometimes the correct play is to take survival or economy and wait for a better chamber rather than spend every reroll immediately.
When to abandon the chase
A good build hunt still needs a fallback. If the Duo or Legendary does not appear by the time the run reaches Elysium or Styx, stop weakening the run for a perfect finish. Upgrade the damage you already have, buy health if needed, and use the incomplete build to clear honestly.
Quick Verdict
Powerful boons are not pure luck. Legendary and Duo boons sit behind prerequisite chains, god-pool control, and rarity pressure. If you know which gods and core boons are required, keepsakes and rerolls can turn a run from random shopping into a planned build hunt.
Pick the Duo or Legendary target before the run starts, not after random boons appear.
Use god keepsakes to force one half of the requirement early.
Check prerequisites before spending rerolls, otherwise rerolls chase impossible outcomes.
Heroic boons are powerful, but a lower-rarity boon that completes the build can be better.
Field Guide
How to use this page
Legendary, Duo, and Heroic Boons Guide should not be treated as a trivia entry. Use it as a route decision before the next run: identify the current wall, then choose the lowest-execution answer that solves that wall.
If the problem is survival, prioritize safer spacing, keepsakes, Mirror choices, or weapon rhythm. If the problem is damage, identify which button carries the build. If the problem is resources, spend on upgrades that improve several future runs instead of only the current attempt.
Screenshots and video references are support material: they help you read tells, spacing, reward locations, or build direction. The written conclusions are the part to carry into the run.
Before entry
Use this Guide page to name the real job first: survival, damage, resources, or route clarity. A specific job keeps the run from being pulled off course by rarity, flashy clips, or tempting side rewards.
During the fight
Compress the advice into one action rule: wait for the tell, preserve spacing, clear adds first, take the core boon, or leave before greed damage begins. Good guidance should survive a messy screen.
After failure
Do not only ask whether the damage was high enough. Ask where health started disappearing, which reward did not serve the route, and whether the next run needs a different keepsake, Mirror setup, aspect, or starting god.
After reading Legendary, Duo, and Heroic Boons Guide, do not jump straight to an unrelated entry. Test the advice in one run by changing a single variable: starting keepsake, primary damage button, boss phase plan, resource spending order, or the positioning shown in the reference frames. That makes the next review cleaner because you can tell which change actually improved the route.
If you only remember one rule: Legendary, Duo, and Heroic Boons Guide is useful because it reduces hesitation in the next run. Anything that helps you decide when to attack, retreat, reroute, or preserve resources is what actually improves clear consistency.
A database page works best when it turns small decisions into a stable route. Read this page, follow the related entries, then test the idea in one escape attempt so the guide becomes practice rather than trivia.

Boon rarity ladder
Rarity affects power, but special boons also require prerequisite logic.

Requirement thinking
Plan the required gods and core boons before spending rerolls.

Codex and memory aids
Use available references to check what a target boon actually needs.

Reroll timing
Rerolls matter most when the desired result is already eligible.
