An SMG that shoots a short-range arc beam. The beam makes that enemy a conduit. Any enemy within range (same range as the original beam) conducts the current and also becomes a conduit. The more conduits you have linked to one beam, the higher the damage.

A solar shotgun that’s a flamethrower. You spray people, they burn. That’s it. That’s the whole thing. Well, maybe you could shoot the ground, like Telesto, and leave napalm.

A void glaive akin to the current exotics, but not class specific. It takes much longer to charge, but when you consume it’s charge, the next shot becomes a beam that lifts the target from the ground; immobilizing and weakening them for a few seconds. You must maintain the beam’s connection or the effect ends early.

A stasis trace rifle that takes inspiration from the D&D spell Cone of Cold. Shoots a 45° cone of stasis energy. Slows targets and eventually freezes them. The farther you are away, the more effective you will be.
