This build scales the majority of its damage by stacking Bleed on a target, and then using Swarm Strike to consume said Bleed via Bloodlust Swarm. It also utilizes Maelstrom's Windswept, Windfury, and Sleet-Footed nodes with Swarmblade Form's Water Strider for our defenses/speed. We do not scale any minion health, so you will need careful placement of Summon Hive to get the most out of it.
Skill rotation starts with using all available Summon Hive charges on the opposite side of your target to ensure Summon Locust can survive during the fight. Then you will stack Bleed with Summon Locust, Armblade Slash, and Dive ( SuffixChance to Bleed on Hit is from the Death by a Thousand Wings node in Swarmblade Form and Serpent Strike's Blood Flurry) for a few seconds before consuming Bleed with Swarm Strike. You will also want to consume as many Summon Locust as you can to gain the maximum possible amount of base damage for Locust Swarm, since each locust consumed increases the base damage. You will continue to use Armblade Slash on tougher enemies and bosses to get damage reduction using Boar Heart from Primal Strength and Impervious, as well as inflicting cold resistance shred from Grand Rage of Winter.
If you choose the Release the Horde, you will want to begin stacking while the hives are in close range. This greatly increases QoL with the build as it will be easier to achieve a good swarm and helps alleviate the frustration of boss aoes by immediately spitting out your max locust count and consuming.
During any amount of downtime, you can maneuver through packs and maintain some damage with Dive and proccing Maelstrom. This will kill trash mobs easily so you can focus on finding a rare or large pack for a new Locust Swarm. You are tanky enough to survive in large packs of enemies to stack huge amounts of Bleed , but just watch out for aoe attacks from a Diamond Matron or a Gorgon.
Something to know with Locust Swarm is that it will scale its damage off the most recent use of Swarm Strike. If you have a strong Locust Swarm, then use Swarm Strike before the duration expires; a new Locust Swarm will be active. This causes us to lose all the possible damage and duration from the previous. You will want to wait until the duration of a good Locust Swarm expires before starting the loop again to use the skill as effectively as possible.
You may be wondering, is the damage of Maelstrom any good? The answer is yes, as I will show in a clip below. It does not get scaled quite as high as Locust Swarm, but it is about 1/3 of our damage and is enough to kill trash mobs without Locust Swarm so the engine does not completely stop running. You may be able to achieve more damage than what you'll see in the video with more optimized rings and relic.
One last thing, Summon Locust will not come out of Summon Hive unless there is an enemy nearby they can target. You won't be able to pre stack a swarm of locust at the start of a mono or boss fight, so keep this in mind running around.
