Flins Build and Guide

Flins is a 5-star Electro Polearm user most commonly played as an on-field Lunar-Charged Main DPS. His gameplay primarily consists of gathering energy from his converted Normal Attack, then using his special Skill to unleash a mini-Burst which deals direct Lunar-Charged damage. As a Moonsign unit, he also features important synergies with other characters in the faction; in Flins’ case, they’re nigh mandatory.

Lunar-Charged is a reaction that replaces Electro-Charged when certain Moonsign characters such as Flins, Columbina, or Ineffa are on the team. It is triggered the same way, and doing so summons a lightning cloud that strikes enemies every 2 seconds starting immediately, dealing Lunar-Charged reaction damage. The aforementioned characters can also deal direct Lunar-Charged damage as part of their kits. All Lunar-Charged damage, similar to Electro-charged, is considered Electro damage, scales with EM, reaction damage bonuses, ignores DEF, and does not benefit from standard DMG%; unlike typical reactions, it can also CRIT. 

Reaction Lunar-Charged damage takes into account the level and stats of all characters who contributed to triggering the reaction based on their damage dealt to the enemy - 100% of the stats of the strongest participant, then 50% and 8% for second and third, respectively. Direct Lunar-Charged damage is based on the multiplier and the scaling stat listed in the ability instead of level, but additionally enjoys a hidden 3x multiplier to its damage. 

Flins’ Moonsign Passive is what allows him to convert Electro-Charged into the Lunar-Charged reaction the rest of his kit relies upon. In addition to this, it raises the team’s Moonsign level by 1 and also increases the Base Damage - a separate multiplier from Reaction DMG% - of all Lunar-Charged damage based on Flins’ ATK, capping at 14% at 2000 ATK. 

Flins’ core gameplay loop is accessed through his Elemental Skill. When used, it causes him to enter a special “Manifest Flame” state for 10 seconds, converting his Normal Attacks and replacing itself with a special Skill called “Northland Spearstorm”, which has a 6-second cooldown. On its own, this special Skill is unremarkable, dealing a minor instance of damage. 

Its true purpose lies in converting Flins’ Elemental Burst into a special variant, “Thunderous Symphony”, for the next 6s. Using it only costs 30 Energy, and causes Flins to launch a plunge which deals direct Lunar-Charged damage; with Ascendant Gleam and a nearby Lunar-Charged thundercloud, however, it deals an additional stronger strike of direct Lunar-Charged damage. Flins typically uses this ability twice per Skill state, and it is where most of his damage lies - hence why Ascendant Gleam and the Lunar-Charged reaction are so essential to his functioning.

His converted Normal Attacks are used in between casts of his special Skill and Burst to generate Energy for Flins, producing 1 Electro particle when they hit an enemy every 2 seconds. Their damage even with the conversion is subpar, though better than nothing; when unconverted, they are generally not worth using at all.

His Standard Elemental Burst costs 80 Energy, and deals 2 minor instances of Lunar-Charged damage followed by another larger instance.  When used in Ascendant Gleam and with a nearby Lunar-Charged thundercloud, it deals 4 minor instances of Lunar-Charged damage instead. The damage total in these conditions is not much higher than his special Burst, and it costs almost three times the energy; while he can build enough Energy Recharge to where this is possible, it is generally not worthwhile and his Burst typically does not see use outside of energy-rich environments.

Rounding out his kit are his Ascension Passives, which are simple but important stat buffs. His first Ascension Passive grants him 20% Lunar-Charged Reaction DMG when under Ascendant Gleam, while his second grants him Elemental Mastery based on his ATK. It caps at 160 Elemental Mastery at 2000 ATK, which Flins aims to reach regardless due to his Moonsign Passive.
