Crow (Black Fire) is a documented evolved, limited-form unit associated by the community wiki with the Villain Invasion update. The wiki identifies the form as Dark and Magical and describes Black Fire and illusion-related effects. Those identity fields make it a useful candidate for late-game damage testing, but they do not make old banner rates, pity, recipes or damage values permanent.
Use this guide to protect your resources and evaluate the form in the current build. The safe order is: confirm availability, inspect the live evolution preview, preserve the base copy, prepare only the displayed materials, and test the evolved unit on the mode you actually want to clear.
Verification: identity was checked against the community wiki on July 28, 2026. Availability, rates, pity, stats, costs, placement limits and recipe quantities need in-game verification.
Confirm the obtainment route before spending
Community records connect the base Crow route to a Villain-themed banner from Update 0.5. That is a historical and community-reported route, not a promise that the banner is still open in every server. Enter the live experience, open the current banner or event interface and look for Crow by exact display name. Check the featured pool, remaining event time and any pity explanation directly in the game.
The Miraheze Crow record reports a 0.01% banner chance and 10,000-pull pity for the documented Villain Banner snapshot. Those are useful historical planning values, not a promise about the banner currently shown in your server. Confirm both numbers in the live banner details before spending; if the banner is absent, do not spend Gems on a similarly named pool.
If you already own Crow, favorite or lock the copy before interacting with evolution, selling or feeding systems. Confirm that the portrait, rarity and name match the base unit intended by the preview. A screenshot can omit variants, shiny states or inventory restrictions that matter to your copy.
Prepare the Black Fire evolution safely
The community wiki documents the following Black Fire recipe snapshot: 1 Crow’s Ring, 20 Red Sprites, 20 Yellow Sprites, 20 Purple Sprites, 3 Rainbow Sprites and 10,000 Gold. Treat the numbers as a preparation target only: the current evolution panel is the authority, and every quantity needs in-game verification.
Miraheze community-wiki value: one Crow-specific evolution material.
Before farming: verify its current source and quantity in the Black Fire preview.
The documented snapshot lists 20 Red, 20 Yellow and 20 Purple Sprites.
Before converting: check each color and quantity in game.
Miraheze community-wiki value: three higher-tier recipe components.
Keep them until the preview confirms the action; do not convert rare materials from memory.
Miraheze community-wiki value: 10,000 Gold in the documented recipe snapshot.
Verify the live cost and leave a reserve for other progression instead of spending down to zero.
When all requirements appear in the live preview, read what happens to the base unit, its trait, stat potential and equipment. Unequip anything the interface asks you to remove. Take one final look at the selected copy, then confirm only if the result name is exactly Crow (Black Fire).
For a reusable checklist, open How to evolve units safely. It covers inventory locks, preview checks and recovery from a missing requirement without assuming one fixed recipe.
Understand Black Fire’s documented role
The wiki associates the evolved form with Black Fire and Illusion, and describes named behavior such as Crow’s Illusion, Broken Mind and Searing Flames. These names are useful for identifying the correct unit card. Their exact damage, cooldown, duration, stacking and enemy interactions are balance-sensitive and should be read from the current skill text.
In practice, evaluate the form as a primary or secondary damage candidate. Place it where its live range covers the longest useful section of the path. Upgrade it only far enough to reach the next meaningful attack or effect breakpoint, then decide whether your economy supports finishing it. If the stage ends before the form comes online, keep a cheap opener beside it rather than blaming the unit’s maximum potential.
Test effect reliability against ordinary waves and the boss separately. Damage-over-time can look excellent on dense enemies yet contribute differently against a short boss phase. Illusion or control-like behavior may also interact with immunity or mode modifiers. Use the enemy panel and stage rules when those are available.
Trait and equipment priorities
Choose a trait after identifying the bottleneck. If Crow misses enemies at the edge of a key corner, test range. If its attack timing allows repeated leaks, compare speed. If it already covers the lane and attacks reliably, damage may provide more value. Rare named traits should not be chased simply because they are rare; rerolling until empty can delay more certain upgrades.
The public assets include an Illusion Crow equipment piece, which makes it a sensible item to inspect for this unit. Compatibility, effects, roll ranges and the best alternative are not confirmed here. Open the live Equipment panel and compare the equipped result on the same stage. The Equipment guide explains how to make that comparison without relying on a single stat total.
Build a team around Crow (Black Fire)
Crow should not be forced to solve every wave. Pair a costly evolved carry with an opener that can be placed immediately. Add one unit for the enemy type or range pattern Crow handles poorly, and reserve a slot for economy or utility only when the mode lasts long enough to repay that choice.
Use a cheaper opener and delay Crow’s first upgrade. Check whether the selected target priority causes overkill.
Read the live target count and effect radius. Add lane control or broader coverage if Black Fire is too concentrated.
Measure Crow’s contribution against another dedicated boss unit with identical support, trait and equipment conditions.
Set a stopping breakpoint for Crow and upgrade the rest of the board. Maximum upgrade is not automatically the best next purchase.
In a squad, tell teammates which path section Crow will cover before everyone places carries at the entrance. Shared buffs, placement limits and enemy timing can make coordinated spacing more valuable than another copy. Exact multiplayer rules need a live-mode check.
A repeatable Black Fire test
Choose a Story act or mode you can enter repeatedly. Record the difficulty, map, party size and modifiers. Run once with your current carry, then again with Crow in the same board position. Keep the opener, support, trait, equipment and upgrade timing as similar as possible.
Compare four results: the first wave where leaks occur, the cash needed before the board stabilizes, the boss clear time and whether Crow’s effects remain active on important enemies. This answers whether Black Fire improves your account now. A showcase’s final damage total cannot answer that if its buffs, map and spending order are different.
Mistakes to avoid
- Spending on an old or similarly named banner without seeing Crow in the live featured pool.
- Treating a community-published rate, pity or recipe quantity as permanent.
- Evolving an unlocked copy without reading the result and retention rules.
- Rerolling traits before confirming that Crow fits the intended stage.
- Equipping an item because the name matches, without checking compatibility and real effect text.
- Comparing the base form, evolved form and another player’s form as if they were identical.
- Filling every expensive slot and leaving no unit capable of opening the stage.
Crow (Black Fire) FAQ
Is Crow (Black Fire) still obtainable?
The form is documented as limited and tied to Villain Invasion-era content. Current availability needs in-game verification. Check the live banner or event panel and official announcements before spending.
What is the exact Crow evolution recipe?
The checked community-Wiki snapshot lists 1 Crow’s Ring, 20 each of Red, Yellow and Purple Sprites, 3 Rainbow Sprites and 10,000 Gold. These are sourced reference values, not a live guarantee; use the evolution preview in your server before farming or confirming.
What is the best trait for Crow (Black Fire)?
There is no verified universal answer. Choose from the failure you observe: range for coverage, speed for attack timing, damage for a stable lane, or a rarer effect only when its live text fits the role. See best traits by unit role.
Is Illusion Crow the required equipment?
An Illusion Crow equipment asset is documented, but compatibility and best-in-slot status need in-game verification. Compare its live effect to your alternatives instead of assuming the name settles the decision.
