Best general [Hildryn] build. Pretty much negates all sortie modifiers as you don't have energy and you strip like 80% armor and shields. Arcanes are important as the only thing that will kill you is toxin procs

High power strength to strip armor and shields as well as damage output on Haven and Elemental ward. Basically you cast Haven and EW then just Pillage and everything will die, don't forget to recast Elemental Ward when you need it.

EW reflects damage back as an electric proc and combined with the heat proc from [Blazing Pillage] you CC most enemies. Also just trust the [Energy Siphon] you'll see. Exilus mod is personal preference I just like the extra damage and knockdown resistance.

There is a separate build for Infested but is uses the same forma and general build. Basically swap [Blind Rage] for [Augur Secrets], [Streamline] to [Fleeting Expertise], and swap elemental ward to Condemn for more reliable shield [Regen] as pillage doesn't work on most Infested. You want low duration and high efficiency for condemn because you can't gain shields from enemies already affected by condemn.

Have fun
