Weapon Option 1: Electric/Gas Helstrum - this applies damage to the most possible enemies per shot to proc both [Energy Generator] and [Synth Deconstruct]. If using [Helstrum], drop [Duplex Bond] for a flexible option (listed below) as Helstrum does not deal suffucient damage to warrant this.
Electric Gas primer helstrum: https://overframe.gg/build/547232/
Viral helstrum is an alternative option which allows more consistent priming: https://overframe.gg/build/547234/
A special heat inherit primer may be useful to boost heat based abilities: https://overframe.gg/build/547236/
For Hydroid specifically, you can use a corrosive primer to strip armor: https://overframe.gg/build/547238/

Weapon Option 2: Viral Heat Verglas - this deals the highest possible damage and still tags a decent number of enemies, and is capable of killing SP enemies. Clones made by Duplex Bond also have an additional chance of making energy orbs on kill.
