Vortex Gaming

· Linea is a character whose all skill damage scales with Defense (DEF). Her Normal Attacks do not scale with DEF, making them less useful.
· Weapon: The 3-star 'Slingshot' is a good F2P option, and her signature weapon, 'Oath of the Golden Frostbound,' increases her personal damage by about 30%. The 'Sacrificial Bow' has unique potential.
· Artifacts: The 'Aubade' 4-piece set is recommended.
· Main Stats: When using Slingshot, choose DEF for Sands, Goblet, and Circlet. When using her signature weapon or Sacrificial Bow, choose Crit Rate for Circlet.
· Talent Levels: It's recommended to level up her Elemental Skill and Elemental Burst to Level 10.
· Note: The current video content is based on the Creator Test Server, and final details may change.

· Linea primarily functions as a support character, reducing enemies' Geo RES by 30%.
· 5% of her Defense is converted into Elemental Mastery (EM) for herself or on-field 'Moonlit' units (approx. 120-170 EM).
· She converts Hydro Crystallize reactions into 'Moonlit Crystallize' reactions, increasing their damage by up to 14%.
· While her signature weapon provides additional team buffs, her support capabilities themselves are not exceptionally strong compared to 'Silonen'.

· When Linea uses her Elemental Skill, her companion 'Lumi' is summoned.
· Tap Mode: Tapping the skill button once summons Lumi in 'Super Power Form,' dealing Moonlit Crystallize and regular Geo damage for 25 seconds.
· Attack Pattern: A Moonlit Crystallize attack (over 100k damage) is followed by two regular Geo attacks (8k damage each), repeating this pattern.
· Moonlit Crystallize Attack Condition: 'Moonlit Drift' must be present on the field. If Moonlit Drift is not present, Lumi will first perform a regular Geo attack, then begin Moonlit Crystallize attacks once Moonlit Drift is generated.
· Preventing DPS Loss: It's crucial to generate Moonlit Drift on the field before Linea uses her Tap Skill. Moonlit Drift is generated when a teammate applies Geo to an enemy affected by Hydro.
· Moonlit Drift Effect: Upon 3 Geo applications, Moonlit Drift triggers 3 Moonlit Crystallize attacks, and when 'Vina's' Elemental Burst is active, it has a 33% chance to trigger an additional attack.

· Mash Mode: Repeatedly mashing the skill button causes Lumi to grow massive and unleash a single, powerful Moonlit Crystallize attack.
· Damage: Even without buffs, she deals approximately 270k damage with 'Slingshot.' This increases to 600k with C6 Gorou's buff, 720k with C6 Illuga's buff, and up to 965k with her signature weapon.
· Concentrated Damage: All damage is concentrated into this single massive attack. Afterward, Lumi only performs two regular Geo attacks every 4 seconds.
· Form Transition: After using the Mash Skill, Lumi transitions from 'Ultimate Power Form' to 'Standard Power Form' and no longer performs additional Moonlit Crystallize attacks.
· Form Distinction: Lumi growing larger during mashing is 'Ultimate,' the star on Lumi's head glowing during Tap Mode is 'Super,' and no star glowing is 'Standard' Form.

· Damage: Assuming Lumi performs 4 Moonlit Crystallize attacks per rotation in Tap Mode, the total damage multipliers for Tap Mode and Mash Mode are nearly identical.
· Key Differences:
· Tap Mode: Contributes more to Moonlit Crystallize reactions due to more Geo applications. Has a short field time of less than 1 second.
· Mash Mode: Has a longer field time of 2-2.5 seconds. Can deal significant damage instantly even without Moonlit Drift.
· Special Advantage: Moonlit Crystallize attacks ignore enemy DEF and have a hidden 1.6x damage bonus.
· Usage Tips:
· If Moonlit Drift is not pre-prepared on the team, use the Mash Skill.
· If Moonlit Drift is prepared, use the Tap Skill.
· If paired with units like Gorou who only buff on-field characters, the Mash Skill is more advantageous.
· The Mash Skill's immense frontloaded damage makes it very satisfying for quickly ending battles.

· Aubade Artifact 4-piece Set: The 4-piece set's 60% Moonlit damage increase buff disappears 3 seconds after the character enters the field. If you switch to Linea and immediately mash the skill, Lumi can deal damage before the buff expires.
· Sacrificial Bow: The Sacrificial Bow's passive only triggers when Lumi deals regular Geo damage. Moonlit Crystallize attacks are not considered skill damage, so they do not immediately trigger the Sacrificial Bow's passive.
· Sacrificial Bow Usage: You must wait for Lumi to deal regular Geo damage after her initial Moonlit Crystallize attack for the skill cooldown to reset, allowing you to use the Mash Skill again. This consumes about 6 seconds of field time, which is inefficient for a support Linea, but can be a fun option if you want to use Linea as an on-field DPS.

· Elemental Burst: Energy cost 60. Upon activation, it heals the entire team once, then provides healing to the on-field character every second for 12 seconds.
· Healing Amount: Based on an F2P 'Slingshot' build, it provides approximately 9350 HP team-wide healing and about 1870 HP per second (12 times total). It recovers a total of approximately 32,000 HP, contributing to team survivability.
· Utility: Useful in certain situations, but not crucial enough to use every rotation, so there's no need to prioritize Energy Recharge.
· Lumi Duration Reset: The Elemental Burst resets Lumi's duration, but it cannot recall 'Ultimate Power Form' after a Mash Skill, only resetting the duration of 'Standard Power Form.' There's no significant advantage for Tap Skill either.
· Exploration Passive (Very Useful):
· Mineral Collection: When Linea marks a mineral deposit with a Charged Attack, Lumi appears, destroying and absorbing all minerals at once. While it sometimes fails to absorb all minerals, it's a very efficient mining method. The mining cooldown has not yet been confirmed.
· Animal Capture: Linea's Charged Attack can capture certain types of animals. It works similarly to the 'Net' gadget, though some animals may die during capture. There is a weekly cooldown, but how many can be captured is still uncertain.

· 'Vinea' Core (Columbina + Linea): The core of Linea's teams is the synergy with 'Columbina.' Teams using these two together are called the 'Vinea' Core.
· Highest DPS Team: A team of Vina, Linea, C6 Illuga or C6 Gorou, and Zhibai has the highest DPS potential in the game. Even with C0 characters and 3-4 star weapons, it can achieve 160-170k DPS. Linea improves the overall DPS of Zhibai teams by 20-25%.
· Revival of Existing Geo Characters: Linea significantly enhances the performance of existing Geo characters.
· C6 Noelle: Very powerful when used with Furina and Vinea. Since Noelle applies a lot of Geo, maintaining Furina's Hydro application is crucial. It performed especially well in the Spiral Abyss.
· Itto: Feels slightly better due to higher personal damage than Noelle. Can use Gorou without an additional Hydro unit, making Linea's Mash Skill easier to utilize.
· Navia: The strongest of the three, but requires additional Hydro application like Furina. Navia's rotation can feel a bit awkward, and unlike Noelle or Itto, her low interruption resistance can make her vulnerable to aggressive enemies.
· Ningguang: Shows surprisingly strong synergy. Ningguang's kit applies a lot of Geo, so a second Hydro unit is essential.
· Artifact Setups: Vina and Linea use the 'Aubade' set, Noelle, Itto, Navia, and Ningguang use the 'Sky' set, and Furina, Gorou, and Illuga use the 'Serenade' set.
· Zhibai Teams (without C6 Gorou/Illuga): Chiori is also a good option. Switching from Chiori to Linea and mashing the skill flows naturally, appearing to be an intended interaction by the developers.
· Sacrificial Bow Linea (On-field DPS): Using Sacrificial Bow can deal over 1 million damage with two Mash Moonlit Crystallize attacks, but its efficiency might be lower outside of the currently buffed Spiral Abyss.
· Vinea vs. Vinepa: Vinea is more restrictive, requiring teams composed of Hydro/Geo units. Vinepa (Vina + Furina) allows for more flexible team compositions.
· Elemental Mastery Buff: Linea's second passive only provides an Elemental Mastery buff to on-field 'Moonlit' units. Characters like Arlecchino or Hu Tao, who are not 'Moonlit,' do not receive this crucial 150+ EM buff, resulting in weaker Vaporize damage.
· Vinea + Hydro/Geo Compositions: Can also be used with characters like Neuvillette. For C0 Neuvillette, she can help trigger 3 reactions via Kazuha to gain Dragon's Sigils, while for C1 Neuvillette, Silonen is a better choice.
· Non-Moonlit Crystallize Teams: Linea can be included in Nefer's meta teams (Rauma, Vina). While C6 Sucrose is the optimal choice, using Linea doesn't result in significant DPS loss, and Linea's healing greatly improves the survivability of Nefer teams without C1 Rauma.
· Teams without Columbina: Furina, Kokomi, Yelan, Xingqiu, Aino, etc., can be alternative units. C6 Aino increases Moonlit Crystallize damage, but Linea's first passive (Geo RES reduction) requires the 'Ascendant Gleam' state, making her less efficient without a 'Moonlit' unit. Aino is less efficient than Vina due to limited combat range and low damage contribution. Vina provides strong sub-DPS and increased Moonlit Crystallize reaction counts.
· Conclusion (With/Without Columbina): Using Linea without Columbina results in significant synergy and damage loss. For Zhibai teams, it's recommended to obtain Vina first, then Linea. An Aino + Linea + C6 Illuga/Gorou composition without Vina is also possible, but it's a much weaker team compared to the previous options.
· Zhongli: Zhongli's pillars can trigger many Moonlit Crystallize reactions, but they are easily destroyed by most large bosses. If you can maintain the pillars and keep enemies nearby, it can be a fun option.

· Linea's companion 'Lumi' is a charming mascot with cute and fun sound effects.
· If you have Vina, Zhibai, and either C6 Gorou or C6 Illuga, Linea will elevate your team to a new power level.
· There's strategic depth in deciding whether to use Tap Skill or Mash Skill. The Mash Skill's immense frontloaded damage is very satisfying.
· The 'Husk' artifact set is also a good option for Linea, and 'Snare Hook' or other 5-star stat weapons are worth considering. More detailed information will be covered in the Linea guide video to be released with the Luna VI update.
· Linea has contributed to ushering in an era where Geo characters are once again in the spotlight, giving existing characters like Ningguang and Noelle a chance to shine again.
· However, Linea becomes much stronger when paired with Columbina, so this should be kept in mind.
