Changelog
What changed
A transparent record of improvements, fixes, and what is next.
Monster reference
Find the right monster for the job
Compare practical roles, notable tags, elements, and content use before you invest.
Tags describe notable contributions, not a complete skill sheet. Check the guide, your runes, and the content goal before investing.
Skill glossary
Decode the battle language
Quick definitions for buffs, debuffs, and turn-control terms you will see in guides.
Definitions are practical shorthand, not a complete skill-text database. Check the in-game tooltip for exact values and exceptions.
Rune reference
Choose a set with a job in mind
A practical set-effect index for early builds, role goals, and content decisions.
Set effects are a starting point, not a complete build rule. Good stats and the unit's job still matter more than forcing a bonus.
Rune main stats
Read every slot at a glance
Use the slot number first, then choose a main stat that supports the unit's job.
Flat main stats are fixed on slots 1, 3, and 5. On slots 2, 4, and 6, a percentage or utility main stat is usually the long-term target, but a strong early rune can still be worth using.
Rune substats
Keep the stats that do a job
Use pairings and realistic benchmarks to decide what deserves an upgrade, not just what looks shiny.
Benchmarks are guideposts, not requirements. A rune with the right set, speed roll, and job can be worth keeping even when it misses a perfect target.
Rune quality filter
Decide what earns inventory space
Score a rune by its stars, grade, rolls, and job before you spend mana or fill the storage page.
This is a practical filter, not a replacement for the unit, set, content goal, or your current inventory.
Artifact guide
Give every artifact a job
Find the effects that support a monster's actual role, then upgrade with a plan instead of chasing every shiny line.
Monster-specific effect tips
Choose the monster's job and content before spending artifact experience.
Artifacts are additive: keep the rune set and core stat build healthy first. A perfect effect cannot rescue a unit that misses its Speed, survivability, or accuracy job.
Grindstone guide
Put every grindstone on a real upgrade
Match the material to the stat, the rune to the monster, and the upgrade to the content that actually matters.
Build an upgrade queue
Choose a job and content lens to see which stats deserve the next safe improvement.
Grindstones improve a good rune; they do not turn a wrong set, weak main stat, or failed speed tune into a finished build. Compare the final stat and the monster's job before spending rare materials.
Gem guide
Replace the weak line, keep the great rune
Use gems to repair a strong rune's one bad substat, finish a real threshold, and avoid gambling away a long-term piece.
Build a safe gem queue
Choose the monster's job and goal before spending a replacement on a rune.
A gem improves the right rune; it does not fix a weak set, bad main stat, missing innate plan, or a build that is far from its actual job.
Rune optimizer
Build for the job, not the screenshot
Describe a rune and get a transparent fit check for the monster role and content you are actually building.
What substats are on the candidate?
This is a role-fit filter, not a promise that one rune replaces your full build.
Check the final Speed, survival, and accuracy thresholds in-game. A high score is a reason to inspect the rune, not permission to ignore the monster's actual stats.
Team builder
Build a team around the job
Choose a content goal, assign each monster a job, and find the missing piece before you spend more resources.
Coverage is a planning check, not a guarantee. Test the final team with your actual runes, speed order, and stage mechanics.
Speed tuning desk
See the turn order before the run
Enter five unit speeds and optional boosts to expose ties, tight gaps, and opener surprises.
Dungeon mechanics index
Know the failure point first
Search the major PvE destinations for mechanics, team jobs, and the next upgrade that makes runs safer.
Cairos upgrade path
Pick the account lens that matches your current goal, then use the cards above to choose the next farm.
Accuracy desk
