All Star Tower Defense 7-star units are high-rarity targets documented across special summons, passes, events, rewards, and evolution chains. Their cost and scarcity make verification more important, not less. Confirm the exact original-game form, current source, live recipe, and intended role before spending copies, materials, Gems, or Stardust.
Seven-star discovery index
These names are not presented as a complete current list or a tier. They are documented forms to verify in the live original game.
Confirm acquisition before planning
Community references associate current and historical seven-stars with Special Hero Summon, Star Pass, events, and other routes. Open the relevant current interface and record the exact pool, timer, currency, recipe, pass season, or event end. If the form is absent, mark the route historical or unknown.
The official description says the regular Summon Gate changes hourly, but that does not establish the behavior of every special source. Read each live panel separately. Do not import pity numbers, rates, or guarantees from an old guide.
Product isolation matters: recent “ASTD” results often cover All Star Tower Defense X. Verify Place ID 4996049426 and reject X-only systems or unit forms.
Decide whether the target fits
Rarity does not remove role constraints. For Story Mode, inspect placement cost and early upgrades. For Infinite Mode, inspect finished output per placement, range, area, boss value, buffs, control, and ability timing. For support, measure team gain rather than personal damage.
Role gain
Name the failure this form should solve. If it only duplicates existing damage while air coverage or economy is missing, wait.
Account cost
Count base units, duplicates, materials, currencies, time, and the temporary loss of any working form.
Source risk
Check event time, banner rotation, pass availability, and whether every ingredient has a live route.
Test plan
Choose the stage, baseline, placement, leader, orb, and result fields before completing the target.
Compare the planned form with an owned six-star or other alternative. An incomplete seven-star chase can delay several improvements that would progress the account now.
Evolution walkthrough snapshot
The following community video can help a player recognize the evolution flow and the kind of menu evidence to capture. It is not an official recipe record. Pause on exact forms, then compare every ingredient and quantity with the current original-game menu.
If the video and live menu disagree, the live menu wins. Record the check date and avoid copying the creator’s title structure or unsupported claims into your own notes.
Protect the evolution chain
Lock the active copy, required base forms, duplicates, and rare materials. Select the exact unit in the evolution menu and record every displayed requirement and output preview. Community evolution coverage is currently under revision, so a missing web recipe must remain unknown.
Prepare a replacement if the base form carries your current Story or farming team. Confirm whether levels, orbs, or other investments transfer according to the live prompt. Never assume transfer behavior.
If a chain passes through six-star, document each stage separately. This prevents a high-level total recipe from hiding which form and materials are needed first.
Farm and verify ingredients
Use Materials to assign every ingredient to a live source. For mode rewards, distinguish first-clear and repeat results. For random enemy drops, log multiple runs. For shops, record price, stock, currency, and timer. For events, confirm there is enough remaining time.
Do not publish an exact drop rate from a small personal sample. Record observed totals and runs. Leave the global rate unknown unless the current game officially displays it.
Stop if one ingredient has no verified route. Finishing all easy materials first can leave the account holding a costly incomplete recipe.
Test the completed seven-star
Lock the result, inspect the full upgrade path, and record stats with the Unit Stats baseline. Test unbuffed first, then in the intended team. Compare against the unit that occupied the same role.
For Story, record opening affordability and wave stability. For Infinite, record finished placements, wave reached, boss health, support sequence, and cooldown state. A high-rarity unit belongs in the meta only after it improves a reproducible result.
Maintain status honestly
Label every listed form live verified, community indexed, historical, or needs testing. Add current source, exact recipe, role, level baseline, and check date. Unknown fields stay blank.
