Genshin Impact Version 6.4, also called Luna V, reportedly launched on February 25, 2026. Its March Spiral Abyss cycle began March 16, with Anemo and Cryo bonuses that varied by floor and chamber half. The update also introduced playable character Varka and the Radiant Moongecko world boss. This retrospective guide focuses on what is established about those three features; the available summaries do not support a complete boss moveset or a reliable Varka build recommendation.

What Version 6.4 added

Version 6.4 was known as Luna V. A HoYoLAB creator livestream summary and a secondary retrospective identify Varka as a new playable character and the Radiant Moongecko as a new field or world boss. The update and its March Abyss cycle are historical, rather than current content. HoYoLAB Version 6.4 summary; Game8 Version 6.4 retrospective.

March Spiral Abyss: bonuses by floor

The reported cycle began March 16, 2026. Its modifiers encouraged Anemo and Cryo damage, but the applicable bonus depended on the floor and, on Floor 12, the half. These bonuses are incentives, not proof that one character or team is universally best.

Abyss area Reported modifier What it favors
Floor 11 All party members receive 60% Anemo DMG and 60% Cryo DMG bonuses. Either damage type can benefit across the floor.
Floor 12, first half The active character deals 75% more Anemo DMG. Anemo damage while that character is active.
Floor 12, second half Normal Attack Cryo DMG is increased by 75%. Cryo damage dealt through Normal Attacks; the modifier does not say all Cryo damage is boosted.

The values and descriptions above come from a HoYoLAB community cycle summary. They describe Abyss modifiers, not a tested clear-time advantage or a universal team ranking. HoYoLAB March Spiral Abyss cycle summary.

How Windlash Moon worked

The cycle’s Windlash Moon effect reportedly accumulated stacks when party members triggered Swirl. After four stacks, it triggered a shockwave that dealt True DMG. Stacks could be gained no more than once every 0.1 seconds, and the shockwave could occur once every six seconds. In other words, a Swirl did not each cause an immediate shockwave: the effect required four stacks and had its own trigger interval. HoYoLAB cycle summary.

Applying the bonuses to your teams

  • On Floor 11, consider teams that can make productive use of Anemo or Cryo damage, since the stated bonuses applied to all party members.
  • On Floor 12, match the first half’s Anemo bonus and the second half’s Normal Attack Cryo bonus to characters and rotations you can actually field.
  • Do not treat the Cryo modifier on the second half as a general bonus to every Cryo ability; its stated scope is Normal Attack Cryo DMG.

Varka: what is confirmed, and what is not

The available summaries identify Varka as a playable character introduced in Version 6.4. They list Gest of the Mighty Wolf as a new five-star claymore. HoYoLAB Version 6.4 summary; Game8 Version 6.4 retrospective.

Those summaries do not establish Varka’s exact skill multipliers, best artifact set, strongest teams, or pull value. The Anemo bonuses in this particular Abyss cycle are not enough to conclude that players should invest in Varka: a temporary floor modifier is not a general character evaluation. This guide therefore does not assign him a build or rank him against other characters.

Radiant Moongecko: what players can rely on

The Radiant Moongecko is identified in the available summaries as a new field or world boss in Luna V. The material available here does not verify a complete attack list, resistances, weaknesses, or an optimal party for the fight.

A secondary retrospective mentions a Moonstone Anchor and advises players to destroy it, but that tactic is not corroborated by retrieved official update notes or a complete, independently verifiable boss guide. Treat it as secondary-source guidance rather than a fully established encounter mechanic. Game8 Version 6.4 retrospective.

Other reported Luna V additions

A HoYoLAB community summary also reports a Mondstadt Chronicled Wish and a catalyst weapon appearance modifier unlocked after a story quest. The secondary retrospective mentions an Adventure Handbook Training Guide tab and other event or system changes. These are brief context rather than the focus of the Abyss, Varka, and Moongecko details above. HoYoLAB Version 6.4 summary; Game8 Version 6.4 retrospective.
