Overview
Linnea is a Sub-DPS and Support for Lunar Crystallize teams. Her Elemental Skill provides an off-field turret that deals Lunar Crystallize damage and applies Geo. It can be cast in two different ways, depending on if it was Tapped or Tapped Repeatedly. The former is usually preferred. Her Elemental Burst will refresh her turret's duration and heal the team.
Lunar Crystallize
When a Lunar Crystallize Reaction occurs, it will spawn 3 Geo constructs called ‘Moondrifts’ near the subject of the reaction. Regular Crystallize has an inherent cooldown of 1 second, but Lunar Crystallize does not. When subsequent Lunar Crystallize Reactions are triggered, they will attack the enemy based on the Elemental Mastery and Crit of the Reaction participants, every 3 Lunar Crystallizes. This means that more Geo application correlates directly to more Lunar Crystallize Reaction damage. The damage of the Moondrifts scales with the EM and Crit of the characters that participated in the Reaction, with priority given to the ones with the highest EM + Crit scaling.
Linnea also has the standard Base Multiplier Increase Passive for Lunar Crystallize damage, making her even further incentivized to be in dedicated Lunar Crystallize teams.
Lumi & Elemental Skill
Lumi, Linnea’s turret, can be summoned and utilized in 3 distinct ways: Tapping her Elemental Skill once, Tapping her Elemental Skill repeatedly, and using her Elemental Burst. When Tapping once, Lumi will be summoned in the ‘Super Power Form’ and periodically strike opponents, averaging roughly 1 hit every 1.8 seconds. If Moondrifts spawned by causing Lunar-Crystallize are around, Lumi will alternate between regular Geo hits and hits dealing Lunar-Crystallize Geo damage. Lumi will always strike with a regular Geo hit first.
When Tapping repeatedly, Lumi will strike the enemies with a significantly stronger hit, worth as much as 4 Lunar-Crystallize hits in ‘Super Power Form’, but will not perform any more Lunar-Crystallize hits in the rest of its uptime. It will perform only regular Geo hits at a slower rate. Overall this will make Linnea do significantly less off-field damage, but it can be useful for bursting opponents down quickly. This nuke hit also gains significant power from Linnea’s Constellations.
Both of these methods share an 18 second cooldown, and Lumi’s duration is 25 seconds. Linnea will generate 3 Geo Energy Particles when Lumi hits an enemy, with a 9 second cooldown. Since Linnea rotations will generally not be much longer than 18-19 seconds, she’ll generate roughly 6 Geo particles per rotation.
Elemental Burst
Linnea’s Elemental Burst, besides healing, will also refresh Lumi’s duration and re-summon it in the Form it was already in. It will not put her Elemental Skill into cooldown though, so you can swap Lumi’s form before or after using it.
This healing is split into a first, team-wide healing instances and several instances of healing the active character, in 2 second intervals for 12 seconds total. Linnea’s Burst has an Energy cost of 60 and is on a 15 second cooldown.
