The local specialty, Crystal Marrow, grows only on Tatarasuna and Yashiori Island. Aslo, Inazuma's Maguu Kenki is the only one with Marionette Cores.In total, players will need the following items to ascend Sayu:Level 2020,000 MoraVayuda Turquoise Sliver ×13 Crystal Marrow3 Whopperflower NectarLevel 4040,000 MoraVayuda Turquoise Fragment ×33 Marionette Core10 Crystal Marrow15 Whopperflower NectarLevel 5060,000 MoraVayuda Turquoise Fragment ×64 Marionette Core20 Crystal Marrow12 Shimmering NectarLevel 6080,000 MoraVayuda Turquoise Chunk ×38 Marionette Core30 Crystal Marrow18 Shimmering NectarLevel 70100,000 MoraVayuda Turquoise Chunk ×612 Marionette Core45 Crystal Marrow12 Energy NectarLevel 80120,000 MoraVayuda Turquoise Gemstone ×620 Marionette Core60 Crystal Marrow24 Energy NectarBest Sayu builds in Genshin ImpactSayu (image via miHoYo)The best Sayu builds will prioritize the effects of her Elemental Burst. This ability summons a creature that heals any party members under 70% HP. Or, if all characters have enough HP, the creature will use Anemo attacks on nearby enemies.Because of her Elemental Burst, Sayu players should focus on increasing either her healing ability or her Anemo sub-DPS potential.Best weapons for Sayu in Genshin ImpactSkyward Pride (iamge via Genshin Impact)Sayu’s best-in-slot weapon will likely be Skyward Pride. At refinement level one, this claymore increases damage by 8% and, upon hitting an enemy, creates a secondary attack dealing 80% of ATK as damage. Most importantly, Skyward Pride increases Elemental Recharge by up to 36.8%, helping Sayu use her burst.Of course, many players don’t have Skyward Pride or are already using it with another character. Fortunately, Sayu has some F2P friendly weapon options.Prototype Archaic (image via Genshin Impact)The Prototype Archaic is a good 4-star claymore with an ATK% secondary stat, making Sayu’s burst damage and healing ability even more powerful. Alternatively, the Katsuragikiri Nagamasa provides Energy Recharge and makes the Elemental Skill stronger. Best of all, both of these weapons are craftable, so players can simply farm materials to bring them to refinement level five.Favonius Greatsword (image via Genshin Impact)Players who have pulled the Favonius Greatsword from the gacha can also entrust this weapon to Sayu. She’s sure to make good use of the Energy Recharge, and the energy gains from CRITs is a nice bonus.Best artifacts for Sayu in Genshin ImpactThe best artifact set for Sayu in Genshin Impact will be Viridescent Venerer. With four Viridescent artifacts equipped, Sayu will get a 15% buff to Anemo damage and a 60% buff to Swirl damage. Enemies will also get a 40% resistance debuff to the element that Sayu Swirls onto them.Viridescent Venerer artifact set bonuses (image via game8)Since Sayu’s healing ability scales off of her attack stat, players should consider getting Sands and Circlet pieces with an ATK% main stat. Another option would be Elemental Mastery, which would make the Swirl reactions from Sayu’s burst much more powerful. An ATK% or Anemo damage goblet is also recommended.Players should keep in mind that Swirl reactions can’t land CRITs in Genshin Impact. Instead of the CRIT rate and CRIT damage, players should focus on ATK%, Elemental Mastery and Elemental Recharge.Best teams for Sayu in Genshin ImpactAs an Anemo support character, Sayu will be a great fit for a number of teams. She will be useful as a healer and debuffer who can also deal some sub-DPS.Xiao SayuAlbedoZhongliPotential new team build!Xiao main DPSSayu with heals and extra anemo damageAlbedo with the skill area buff damageZhongli with the shield protection pic.twitter.com/h9UCePVGDu— 👾Lobapixel👾 (@Lobapixel) August 5, 2021Sayu could work well on a team with Ayaka, Xingqiu and Venti, for example. Ayaka would be the main DPS while Xingqiu helps freeze reactions. Venti would help with multiple enemies and deal burst damage. Sayu, meanwhile, would Swirl the Viridescent Venerer debuff and create Elemental Resonance with Venti.Players have more options outside a top-tier team. Characters like Xiangling and Fischl can also be useful with Sayu, helping create infused Swirl reactions.Overall, Sayu would be a great healer for many teams in Genshin Impact. More play-testing will reveal how she stacks up to other support units, but players needing an Anemo healer can easily entrust Sayu with that role.Also read: Genshin Impact 2.1 leaks reveal Aloy's ascension materials
