I’ve been playing with the Luna lately, and it’s great fun for corner fights and for making close-range trickshots. Despite its meager range, it seems to work well on a majority of maps and game modes besides Splat Zones as long as your team has good map control, which might be alleviated by the Neo’s bombs (using it on Kelp Dome is suffering, though, and at that point I opt for Range Blaster or something else entirely to bully the tower). But I’m curious about what builds Luna players generally use.
Damage Up increases the effective kill radius on the AoE burst, of course. I’m running a Damage Up main on my head and a couple sub damage ups and the inner ring of the AoE is doing about 80 damage per shot, which is enough to secure kills on even lightly-injured enemies. I imagine running a damage up main and, say, three damage ups on a rather unfresh Anchor Sweat would get you close to 100 damage on the inner AoE. I’d like some confirmation from other Luna users whether this is the case, since I have no way of testing it myself at the moment.
Swim speed is also great, since it lets you get to mid faster and assassinate targets that get too close while the rest of your team catches up. It also lets you chase fleeing targets as well as juke them better in 1v1s. I had two Swim Ups on my red lo-tops and another one on my Urban Jacket, but I got greedy and rerolled the lo-tops with my remaining snails. Now they have no Swim Speed Ups. Alas.
I’m just not sure what else I’d run. Luna is already great in terms of ink efficiency; when the Neo Luna rolls around, Sub Saver might be useful. Though you’d still want to take Damage Up to increase the kill radius on your bombs.
