Windflit is an Artificer Supporter who specializes in buffing Casters and Supporters through ATK buffs and restoring SP. He can be used as both a blocker and a buffer (for the aforementioned classes), but he isn’t the best in either regard. He struggles to effectively employ his branch gimmick due to a mix of short-lived devices and poor numbers attached to them. The only way of restocking these devices is a skill with a long cycle, making them very unsustainable. His DPS is similarly lacking, making him just another blocker on the ground in most circumstances.

  • S1 AoE has no target limit, letting him contribute in denser waves against most low DEF mobs
  • Can slightly boost the DPS output of up to 2 Casters/Supporters or focus on one operator if timed correctly


  • Devices are time-limited, grant small buffs individually, and are not available frequently enough to make much of a difference in a team
  • Very subpar damage output regardless of skill; lacks any sort of survivability buffs that could give him a significant edge over lower-cost Vanguards


Forward Together

Carries 3 Reliable Batteries that only take effect on Casters and Supporters (max 2 deployed at once). Equipped units gain +15% ATK (lasts 30 seconds)

Note: The devices can be placed on deployable melee and ranged tiles

Windflit’s batteries can recover SP to the target or give them a larger ATK buff depending on the skill. While they can stack, they’re wasted if used without his S2 talent amplification. Batteries take 15 seconds to be deployed after the last, which means using more than one demands tight timing to be paired with his S2 activation. The utility offered by these devices is usually outclassed by stronger ATK buff or SP battery options, some of which come as a secondary aspect of another unit’s kit.

The skill has passable damage output against a single target and will allow him to contribute in denser waves when hitting multiple targets. The charges help make use of downtime. It is a lot more consistent than his S2, but offers no way of replenishing devices after they’re used and no easy way to significantly boost their output.

When using this skill, consider the devices as individual one-time boosts of up to 5 SP for the operator they’re equipped to. This is only true if he is consistently proccing the skill for the 30 seconds the devices are up, and in practice it’ll often only be 2-3 SP. The SP recovery effect takes place after the skill ends, allowing Windflit to fuel his own skill uses.

Skill Mastery

Recommended Rank

The skill simply isn’t effective enough to recommend mastery even to truly dedicated players. While not a recommendation, those who want to have at least one M3 skill on Windflit might consider it exclusively for the extra charge and multiplier increase. The SP cost reduction is only significant when used alongside a +0.4SP/sec battery such as Suzuran. This amount of additional SP allows Windflit to trigger his skill one attack earlier than usual, making a more noticeable difference between SL7 and M3.

Attack interval increases, ATK +160%; Talent ATK bonus increased to 2x; When the skill ends, obtain 1 Reliable Battery

While the ATK buff may seem big, being paired with Windflit’s slow attack interval, made even slower by this skill, results in a damage output that leaves a lot to be desired. It has an extremely poor uptime and lacks the damage to truly make it a burst skill worth considering.

If using this skill, consider it as purely a tool to strengthen the buff his devices offer. When fully invested in, Windflit can give a decent ATK buff to one target, or spread the buff between two targets. It will require some precise timing to get the most out of and is quite subpar when compared to other buff options, both single and multi-target.

Skill Mastery

Recommended Rank

Mastery doesn’t touch on the biggest downside of this skill—its disproportionately large SP cost. The most relevant upgrade from the masteries of this skill is the ATK increase to Windflit himself, with additional initial SP and talent multiplier not offering much. The talent multiplier upgrade is just an additional 4.5% ATK, 9% if both batteries are used on the same target. .
