What the Sigil solves
Sigil of the Dead is not just a flashy late unlock. Hades Aid can let you leave unsafe pressure, reposition behind a target, avoid a dangerous sequence, or set up a cleaner burst window. Its value depends on using invisibility before the room becomes desperate, not as a panic button after every other plan has failed.

Call slot tradeoff
Because Sigil changes the Call plan, compare it against the Aid your build would otherwise use. Zeus, Artemis, Aphrodite, Athena, or Dionysus Aid can all support different routes. Pick Sigil when invisibility and control matter more than another god call payoff.

How to use this page in a run
Use this page as a quick decision aid before the next chamber or boss attempt. First identify the immediate problem, then pick the recommendation that solves that problem with the least extra execution. If the page is about a weapon or resource, treat it as a route choice rather than a trivia entry: the goal is a more stable run, not just knowing the item exists.

High-retention guide pages do not force every player to read linearly. They help the player name the problem, act on it, then continue into the next useful page.
01 · Opening pick
You are deciding whether to start with Sigil of the Dead
A keepsake is a route switch, not permanent equipment. First identify whether it solves god targeting, survival, economy, boss protection, or late utility.
Page action
Requires late relationship progression before it becomes available.
02 · Biome swap
You cleared a biome and can change keepsakes
Do not keep the same keepsake by habit. Ask whether the next stretch threatens normal rooms, the boss, resources, or a missing core boon.
Page action
Use for late-game routing, Call-slot experimentation, or builds that value safe repositioning more than raw Olympian Aid damage.
03 · Trap check
The keepsake looks strong, but may not fit this route
Many keepsakes are powerful only inside a matching plan. Use the mistake notes to spot when the reward is not worth the opportunity cost.

Forgetting that choosing Sigil also means giving up another god Aid.
Field Guide
How to use this page
Sigil of the Dead 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 Keepsake 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 Sigil of the Dead, 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: Sigil of the Dead 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.

Strategy Path
What to read next
Do not leave Sigil of the Dead as an isolated note. Follow the route below to turn one useful answer into a complete escape plan.
01 · Solve the wall
Hades
After Sigil of the Dead, use Hades to check the next decision layer: Stay outside spin range, clear skull casts before they detonate, and never spend all dashes entering melee. Phase two is won by patience, not by racing the health bar.
02 · Build the route
Hades Boon and Build Planning Guide
After Sigil of the Dead, use Hades Boon and Build Planning Guide to check the next decision layer: A good Hades build starts by deciding which button deals damage. Then you pick gods that scale that button, use keepsakes to control the first god, and avoid taking shiny boons that do not help the run’s core job.
03 · Build the route
Hades Nectar and Keepsake Priority Guide
After Sigil of the Dead, use Hades Nectar and Keepsake Priority Guide to check the next decision layer: Early Nectar is best spent unlocking useful first keepsakes. Survival keepsakes help you see more bosses; god keepsakes help you build intentionally once you understand what your weapon wants.
04 · Plan upgrades
Nectar
After Sigil of the Dead, use Nectar to check the next decision layer: Give early Nectar to characters whose keepsakes solve immediate problems: Skelly for survival, Cerberus for health, and Olympian gods for boon targeting.
Change one variable at a time along this path: setup first, boon route second, boss phase handling last. That makes it easier to tell which adjustment actually improved consistency.
