A Simple build for my old man, using mods he has as a new player
[Redirection] and [Vitality]: These are basic survival mods. Not necessary on all frames, since some of them can survive simply by not being shot in the first place, they are nonetheless nice mods to have equipped
[Continuity]: Affects the 4th and 2 abilities, lowering the energy drain while [Exalted Blade] is active and increasing the blind from Radial Blind. Primary use here is for [Exalted Blade], allowing you to slay enemies with ease for longer
[Intensify]: Affects the damage done by all but the 2nd ability, Radial Blind. More damage for damage abilities is always nice
Streamline: Affects all abilities, lowering the activation/energy cost of them. This allows you to use more abilities with the same amount of energy
[Flow]: Increases your total energy pool. It was added to increase the time spent in your 4th ability, [Exalted Blade]
[Energy Siphon]: This is an Aura mod, which is unique in that it adds to the total mod capacity (similar to Stance mods on melee weapons). This one recovers you energy over time
