My main primary Gaze, built for crit and viral status. Tremor grip means maximum damage but short range - hence the inclusion of Sinister Reach. Riven is what I currently use for the Gaze - look for multishot, crit damage, crit chance.

The AoE at the end of the [Gaze]'s beam allows it to hit multiple enemies at once, making it a nice status primer if you really wanted to use a beam weapon for that purpose.
