To tackle 'Altruia', which has arrived with an Iron-code weakness in Goddess of Victory: NIKKE, top-tier players have thrown every Iron-code unit they own into the fray. The list includes some questionable choices that might make you think, 'Really? They're actually using them?' Three out of the four units receiving 'Treasures' in 2026 are currently taking center stage in this Solo Raid. Furthermore, the entire roster from the 'Lycoris Recoil' and 'Stellar Blade' collaborations has checked in. Here’s the breakdown of the units the pros are using to dismantle Altruia.

Solo Raid Top 50 Rankers: NIKKE Pick Rate Ranking

※ Based on squad data from the 'Solo Raid (Altruia)' event running from February 19 to February 25.
※ Please note that current ranker decks may vary slightly.

As of February 23, the pick rates for the Altruia Solo Raid are in. The 10 units used by all 50 top-ranked players are: Burst I units 'Little Mermaid' and 'Treasure Tow'; Burst II units 'Mast: Romantic Maid', 'Nayuta', and 'Crown'; and Burst III units 'Soda: Twinkling Bunny', 'Treasure Drake', 'Rapi: Red Hood', 'Eve', and 'Raven'.

Furthermore, a slew of 'Treasure' units are making waves, including Tow, Drake, 'Miranda', 'Mokdan', 'Zwei', 'Frima', 'Privaty', 'Helm', and 'Julia'. Privaty and Mokdan have truly proven their worth in this debut Solo Raid. Zwei has emerged as the latest high-scoring component for 'Snow White' compositions, effectively giving Miranda a run for her money.

The surprises of the season were Frima and Julia. Frima was utilized by only one ranker in our data sample, but her ability to boost 'damage ignoring defense' for all allies made her a tactical pick for the 'Chisato Nishikigi' and 'Takina Inoue' pairing.

Outside of single-target attacks, Altruia’s damage output is rather manageable, allowing for a bit of 'tanking' if you’re feeling brave. However, don't get too cocky; not all units are built like a brick wall. When you see the red danger indicator on a single-target attack, you’ve got about 3 to 4 seconds to duck behind cover.

Then there are the core gimmicks: 'Saint's Radiance' and 'Strongest Shield on Earth'. For 'Saint's Radiance', nine parts will appear around Altruia; they must turn blue to be vulnerable. You have exactly 7 seconds to destroy all nine. Fail to clear even one, and Altruia gains invulnerability. Every remaining part extends that window, so time your Full Burst carefully.

Afterwards, Altruia deploys two shields. During this phase, she gains massive defense, reducing incoming damage to a mere '1' unless you're using specific attack buffs or defense-ignoring skills. Break the shields quickly to expose her core again. If you fail to destroy them, they persist for 18 seconds—a massive DPS loss you simply can't afford.

The popular builds among rankers include: 'Crown - Little Mermaid - Rapi: Red Hood - Eve - Mast: Romantic Maid', 'Tow - Nayuta - Soda: Twinkling Bunny - Dorothy: Serendipity - Treasure Drake', 'Treasure Miranda - Bunny Ade - Snow White - Aida - Summer Helm', 'Liter - Grave - Raven - Snow White: Innocent Days - Treasure Privaty', and 'Treasure Mokdan - Takina - Chisato - Diesel: Winter Sweets - Mihara: Bonding Chain'.

Sharp-eyed Commanders will notice the heavy reliance on limited-time characters. Eve, Raven, Takina, Chisato, and Aida are collaboration-locked, while Dorothy: Serendipity, Diesel: Winter Sweets, and Summer Helm are seasonal. Out of 25 units, 8 are limited, and the 'Treasure' units require Level 3 investment, setting an incredibly steep barrier to entry. That said, missing these doesn't make the Solo Raid impossible—just a bit harder to hit the top 3%.

Budget alternatives include Milk: Blooming Bunny, Treasure Laplace, and Treasure Julia. These top-tier compositions are reserved for those with the full roster and maxed-out Treasures, so take them as a reference point. Also, watch out for final-day pushes, as last-minute squad adjustments are common before February 25.

Champion Arena Top 8 Ranker NIKKE Pick Rates

※ Based on data from 40 squads of top 8 rankers in the 'Champion Arena' from February 12 to February 25.
※ Note that the aggregation groups change every season.

In the Season 23 Champion Arena, 'Scarlet' has made a comeback after her 100% pick rate was shattered by the arrival of 'Label'. It seems players are betting on the odds of not encountering a Label. Meanwhile, Label’s pick rate stagnated in the 20% range. Interestingly, Treasure-upgraded Mokdan, Privaty, and Centi remain staples in the arena, proving that Centi’s utility is far from dead.

Privaty, having been absent since the early days of the Special Arena, has returned in force following her Treasure upgrade, with two players in the top 8 utilizing her. We’ll have to see if her adoption rate climbs further in Season 24.

Looking at the squad of Scarlet, the season winner, it’s shocking to see they managed to win without even touching Mokdan’s Treasure upgrade—a testament to Mokdan’s raw base stats. From the round of 8 to the finals, their undefeated squad was 'Blanc - Snow White: Innocent Days - Biscuit - Label - Cinderella'.

The 'Vesti: Tactical Up' composition struggled until the finals, where it finally secured a win in the first match. Scarlet’s deck then rattled off two consecutive wins, and a final 'Snow White: Innocent Days - Cinderella' push clinched the title. It makes one wonder if they'll bother crafting the Mokdan Treasure for next season.

Solo Raid Meta Analysis

Iron-Code Raids: A High Barrier to Entry

Iron-code is arguably the weakest element for DPS units in the game. With two units requiring heavy Treasure investment and three being time-limited, new players are hitting a wall. Once those limited characters are gone, there’s no way to obtain them, which is a major pain point.

Furthermore, your ceiling depends heavily on how well you've built Snow White, which is a source of immense stress for those serious about Solo Raids.Opinions on the Lycoris Recoil collaboration remain divided, largely because players are forced to choose between ignoring the Iron-code raid or over-committing. Commanders are simply hoping for more solid, non-limited Iron-code units in the future. Perhaps the next anniversary Pilgrim will finally bring some much-needed relief to this element.

User Poll: How do you decide where to invest your Treasures?

In our previous poll on Treasure upgrade priorities, 109 Commanders voted, and Mokdan and Privaty tied for first place. It seems the performance boost is just too good to pass up. Of course, many are also just happy about the gorgeous new illustrations. Zwei took third, and Centi landed in fourth.

So far, 17 NIKKEs have received Treasures, complete with exclusive stories, art, and stat bumps. What’s your personal criteria for investing in a Treasure? Let us know in the poll, and we’ll reveal the results in next week’s Meca Ranking.
