Hello there,

Since the goal during the shield phase is pure burst DPS, the [Tigris] stands as one of the best weapons without a Riven.

The build above is not fully optimized (damage calculations are complicated with [Chroma]), but it has a nice damage spread that allows you to take down Electricity, Viral and Slash shields in two hits.

Optimization might allow for it to consistently one shot, but I haven’t done thorough testing with this yet. Either way, the [Tigris] is more than serviceable as a primary weapon.

Enjoy, THeMooN85
