Skill Review

Void Bullet Hail
An assault-support skill that imposes the impair debuff onto enemies. With a fair sp-cost and cooldown, the user can inflict a slight aoe impair (impairment bullets pierce) for a good 12 long seconds. Then for 5s, the user gains a status Iron Will, permitting them to extend and increase the impairment even further. While there exists better and quicker methods of impairment (ie: Mjolnir and Celestial Hymn), this weapon skill permits the user to be “self-sufficient” such that they will not need to rely on another Valkyrie to decrease the enemy defenses. As such, the user is able to inflict tons of damage following the usage of this skill.

Iron Will
The “passive” offers bonus Crit DMG and Shield DMG, which is great for Physical valkyries. This passive is only triggerable via the active weapon skill. So in a sense, it's an extension of the active weapon skill as well. This passive makes it easy for the user to quickly bypass enemy DEFs and deal even more DMG. After this 5s passive ends, the user gains a “6s time window” referred to as the Iron Legacy. During this time window, if the user exits, the team gains a good bonus of Melee Crit DMG for 12 long seconds. This secondary passive is great for supporting Physical Melee Teams and encourages the user to switch out.

Void Drifter

Void Drifter (VD) is Kiana's Valkyrie Ranger's newly Augmented Physical-DMG dealing battlesuit who is the best choice as a user to equip the ARC Serratus. The idea behind fully utilizing ARC Serratus is to use its weapon skill, quickly max out the impair with combo attacks, and switch out to a Physical Melee DPS. This playstyle suits VD very well because VD is a great shield breaker and short-term damage dealer. Her Inner Turmoil skill encourages switching out. When VD switches out upon entering Inner Turmoil, her team gains SP and Total DMG Multiplier for the same 12 long seconds. As such, when VD equips the ARC Serratus, she has the role that mixes between sub-DPS and Supporter. 


And


While the following combo-hitting pistols Valkyries can use ARC-Serratus, they can only utilize the weapon partially at best. Knight Moonbeam (KMB) is a DPS Valkyrie who sees the ARC Serratus as an option. However, because KMB enjoys being out for a much more prolonged time, the switch-out playstyle that the weapon encourages conflicts a bit with these two. The good thing is that they can quickly max out the stack impair from Iron Will. 

Following after that are Divine Prayer (DP) and Valkyrie Ranger (VR). Both are support valkyries that cannot really utilize the damage dealing bonuses of the weapon and are also rather slow in building up 5 combo hits to max out the impair stacks. As support, they are good in their rights via healing and gathering respectively. Due note that on the 10th second out of the 12 seconds, DP's passive Divine Penalty can override a single target's ARC Serratus impairment with a new one.


Conclusion

Here is a chart comparison between all impairing Pistols at their max levels.
 

Pistol Effect Cost Cooldown Stats

ARC Serratus

40-60% Impair
12s


50% Crit DMG
50% Shield DMG

25% Melee Crit DMG for team
12s

18 SP 13s 298 ATK

Xuanyuan Pistols
60% Impair

18 SP 12s 165 ATK
16 CRT

While these pistols all cost the same in SP, it's clear that the ARC Serratus has the longest cooldown. It also takes the longest to reach its max potential of a mere 60% impair that can be outdone by the other pistols and DP's passive Impair. However, it is also the longest lasting impair. I do not think the ARC Serratus can replace the other pistols as a support weapon. Mjolnir and Xuanyuan Pistols, while short lasting, are most effective immediately and therefore are the better choices for support valkyries such as DP and VR. However, it also cannot place VD as a primary Damage dealer as opposed to the Tranquil Arias. VD, with the ARC Serratus, has a role as secondary-DPS with a hint of support. As a result, this is not a weapon to invest in if you are highly competitive. However, it is a great weapon for casual players who do not wish to invest too much time and resources into upgrading other equipment and thinking during gameplay.
