A normal, non-helminth build for Baruuk.

Desert Wind Build: https://overframe.gg/build/136136/

The low duration makes eroding restraint via lull, the downside of this low duration is that many of the helminth infusions that come to mind are no longer viable with no duration. (See my Helminth [Baruuk] for an alternate build).

The base range here is also good, as it means less recasting of your 3 to maintain its 90% damage reduction.

[Reactive Storm] modifies the base impact damage of Desert Wild to the damage type your last enemy hit is weakest to. (this means your 1st hit will always be unmodified, and as its converting base impact, modding impact is worthless as once the change happens they no longer have any impact to add to)
And at 227% you are able to [Reach] 100% status chance, however, this is not enough as you want to be proc'ing both your modded combined element and whichever type they are weakest to.

Other than occasionally needing recast your 3 and 2 for mitigating damage and maintaining the restraint meter, all you need to do is hit enemies before they hit you. While you do have enough EHP to take a lot of damage, you have no way of healing outside of operator arcanes which is time spent not dealing damage.

Additionally, you will want to run a stat stick Zaw ( https://overframe.gg/build/136137/ ), any zaw type with slam built into the combo's works, with the 3 gladiator mods equipped. you will occasionally go out of Serene Storm to stack combo on your stat stick up to 12x before going back into the 4. you do need to be careful though to avoid gaining combo on [Desert Wind] tho, as doing so will reset the gladiator set bonus until you recast the 4.
