Anime Adventures Idol in our tier list
Watch It is on our watch list, not in a tier: only two creators include it in their UPD 21 lists, and we rank a unit once three do. Its cost cut, damage boost and High Cost removal are well supported. See the full Anime Adventures Tier List.
Anime Adventures Idol strengths and weaknesses
Strengths
- Idol lowers the upgrade costs of your units and adds a damage boost; four sources, three of them creators, agree on both.
- It removes the High Cost modifier in challenges, a point that a UPD 21 tier list and an older update log both make.
- The 2025 records say the buff reaches your units wherever Idol (Star) stands on the map, so any spare ground spot works.
Weaknesses
- Before it evolves, Idol only boosts damage on the 2025 record; the upgrade-cost cut needs Idol (Star) and an Idol Mic.
- Every percentage on this page dates from April 2025, before UPD 21, and we have not checked any of it in game.
- Idol was not featured on November 3, 2026, so the 400-summon pity on the Special banner did not point at it.
Our take
- Our read: summon for Idol once you own a few good damage units and their upgrade bills start to slow you down. Before that, Gems do more on units that deal the damage.
- When you watch a damage test, check whether Idol is on the field. Its discount and boost change the numbers, which is why one creator leaves it out of first looks at new units.
How to get Idol
Idol is a Mythic support in Anime Adventures, the Gomu group’s tower defense game on Roblox, and you get it from the Special banner. On November 3, 2026 the rates panel listed Idol in the regular Mythic rows at 0.652% of the Mythic rate, which the same screen showed at 0.5%. Each summon costs 50 Gems.
At capture time on November 3, 2026 the featured Mythics were Thunder Maid, Zombie and Bloodcry, not Idol, and the banner rotates. The 400-summon pity belongs to the featured units, so it does not guarantee Idol. The full panel is on our anime adventures banner rates page.
One creator says to summon for Idol rather than trade for it, because the banner gives it out easily, and still calls it Oshi in a UPD 21 tier list. The update log on the community wiki, last edited before UPD 21, lists an older name, Oshy, with the evolved form as Oshy (Idol). The same log says Idol debuted as a Cake Hunt battle pass unit in Update 12.5 (April 2023), and that Update 14 (June 2023) put a non-limited, untradable version on the Special banner.
What Idol does
Four sources, three of them creators, agree on Idol’s two main effects: it lowers the upgrade costs of your units and gives them a damage boost. Two of them add that the cut covers upgrades, not placing a unit, so budget placements at full price.
Idol also removes the High Cost modifier in challenges. A UPD 21 tier list says so, and the update log dates the change to Update 19.5 (February 2025). Bring it for High Cost challenges.
The rest of the kit comes from the Idol and Idol (Star) wiki pages, last edited in April 2025. UPD 21 may have changed any of it, and we have not checked it in game:
- The unevolved Idol adds damage and nothing else. The upgrade-cost cut arrives with Idol (Star).
- Idol (Star) takes 1 placement, stands on the ground, has no attack of its own and cannot be sold.
- The buff reaches your units wherever Idol (Star) stands on the map.
- It covers Physical and Magic damage and only affects your own units.
- It stacks with Commander, Wind Dragon and Griffin (Ascension), but not with Blossom.
Creators do not say which form they used, so a clip that shows cheaper upgrades may be an evolved copy.
Idol (Star) evolution
Idol (Star) is the evolved form, and the only way to get it is to evolve Idol. No creator video names it, so the name and every number in this section come from the same 2025 pages.
Evolving takes 1 Idol Mic, per an Evolution page that lists no UPD 21 units. You either crafted that Mic or picked it up from the paid Cake Pass, at its tier 50. Neither the in-game item name nor the UPD 21 recipe is confirmed, so do not plan on a pass handing one out.
| Level | Upgrade-cost cut | Damage boost |
|---|---|---|
| Placed | 5% | 5% |
| Upgrade 1 | 10% | 7% |
| Upgrade 2 | 15% | 10% |
| Upgrade 3 (max) | 20% | 15% |
The total cost is listed as 16,000 yen: 1,000 yen to place it plus 3 upgrades. In short, Idol (Star) is the form that adds the cost cut.
Best traits for Idol
Upgrade-cost cut at max upgrade
The chart at the top of this section shows the 2025 figures: a 20% upgrade-cost cut at max upgrade, or 24% with Golden, stepping 6%, 12%, 18% and 24% from placement to upgrade 3. The in-game Trait Chances screen on November 3, 2026 listed Golden at 0.15% per reroll with +30% Damage, +10% Kill Money and +20% Farm Money, and said nothing about upgrade costs. So the 24% rests on the 2025 record alone.
Skip range rolls. Because the buff reaches the whole map, our reading is that Range I to III and Sniper, which the in-game screen lists as range-only rolls, add nothing to what Idol gives your team. Those pages do not discuss traits; that step is ours.
A pair of videos show a Mythic or Secret reroll taking 5 Star Remnants, and the in-game panel shows that a reroll replaces the current traits with no option to lock one. Every roll and its odds are on our anime adventures traits page.
Is Idol worth pulling?
One showcase with and without Idol
Each of these views comes from a single creator:
- One kept Idol with the A-tier supports but said it nearly went into S and probably will, mainly because it removes High Cost.
- Another rates Idol above Zombie as a buffer, since cost reduction matters so much in this game.
- A third says it is not worth chasing at the start, but worth summoning once you have a few good units, and later lists it with Erwin, Wendy and Griffith as endgame supports.
- A fourth leaves it home when money is not tight; the second agrees, and both bring it mainly to discount expensive carries.
The chart at the top of this section is one test from a single video. An evolved Rudo at max upgrade read 252K damage before Idol was placed and 290K after, with attack time (7.3 s) and range (43.4) unchanged; Griffith’s buff came later. The passive on Rudo and other effects were not controlled, so we do not turn the gap into a percentage. In other tests, three creators stack Idol with Griffith and more buffers at once, and those totals cannot separate Idol’s share.
It is on our watch list rather than in a tier. Two creators include it in their UPD 21 lists, one in A and one as a buffer without a tier, and we rank a unit once three do. The cost cut, damage boost and High Cost removal are well supported. The thinner part is the evidence: the percentages date from 2025, the cut may need an Idol Mic with no confirmed UPD 21 recipe, and Idol deals no damage itself. If you are still building your first damage units, wait. If upgrades on an expensive carry slow you down, Idol is a sound pull. The full ranking is on our anime adventures tier list, and our anime adventures units hub has the other UPD 21 pages.
What to pair with Anime Adventures Idol
- Rudo: In a single test an evolved Rudo at max upgrade read 252K damage before Idol was placed and 290K after. One run with nothing else controlled, so take it as a hint.
- Expensive damage dealers: Two creators bring Idol mainly for the upgrade discount, which matters most next to carries that cost a lot to max out.
Anime Adventures Idol FAQ
Is Idol good in Anime Adventures?
Yes, as a support. It cuts upgrade costs, adds a damage boost and removes the High Cost modifier in challenges. Only two creators list it so far, so it is on our watch list rather than in a tier. One nearly put it in S; two others leave it home when money is not tight.
How do you get Idol in Anime Adventures?
Summon on the Special banner at 50 Gems a pull. On November 3, 2026 Idol sat in the regular Mythic rows at 0.652% of the 0.5% Mythic rate. It was not featured then, so the 400-summon pity did not cover it.
What does Idol (Star) do in Anime Adventures?
Idol (Star) is the evolved form, a name only the community wiki gives. Its pages, last edited before UPD 21, say it adds the upgrade-cost cut: 20% off upgrades and a 15% damage boost at max upgrade.
What do you need to evolve Idol?
One Idol Mic, according to an Evolution page that lists no UPD 21 units. Players either crafted it or took it from tier 50 of the paid Cake Pass. Neither the in-game item name nor the UPD 21 recipe is confirmed.
What is the best trait for Idol?
Golden, if the 2025 numbers still hold: 24% off upgrades at max instead of 20%. Skip range rolls. The buff covers the whole map, so in our reading a Range trait adds nothing to it.
Does Idol remove High Cost in Anime Adventures?
Yes. A UPD 21 tier list and the update log on the wiki both say Idol removes the High Cost modifier in challenges. The log dates the change to Update 19.5, in February 2025.
Is Idol the same unit as Oshy?
Yes. The wiki update log lists Idol under the older name Oshy, with the evolved form as Oshy (Idol). One UPD 21 tier list still calls the unit Oshi.
