Wisp Plague Star Build
150 duration with 300+ strength is a must on [Wisp], 150 duration will give 45 seconds of motes buff, which will be 2 hemocyte before allies need to refresh the buff and 300+ strength will give your allies 60% fire rate and movement speed buff as well as 90 health per second. Be a good supporter and have these as minimum standard for [Wisp].
[Umbral Vitality] can be replaced for [Primed Sure Footed].
Use Light emission color, so that u can use [Rage] from rest and [Rage].
Replacing Sol Gate for rest and rage (not a must but its good to have it if loki isnt equiped with it) because all other abilities are needed. Wil-O-[Wisp] is a good ability to cast when the boss is out to distract the ads so that you can focus on the boss.
For the primary i use [Shedu]. (You can use whatever you want)
For the secondary my go to choice is [Pyrana Prime] with blast dmg. (This is a must, there are other weapons but [Pyrana Prime] is the one I liked the most)
For the melee i use [Vastilok] for armor strip on the hemo. (You can use [Sarpa] as well)
