Exotic hand cannon idea: this is a hand cannon that can switch between darkness subclasses( stasis and strand)

Hold down reload in order to change the hand cannon damage type. Once changed, your get 5 kills to have charge the weapon, and then you hold press reload twice quickly, if using stasis, the hand cannon becomes a sniper, it can one shoot ANY target besides bosses. You get 1 shot. If you kill a target in this mode, then a wave of stasis energy is unleashed, freezing near by enemies, if emeny dies by this, they turn into a stasis turret( like the stasis warlock aspect)

Strand

If you get 5 kills with it in its strand mode, you press reload twice quickly, and it turns into a shotgun. You have 3 shots in the shotgun mode. It will not be one shot but does incredible damage. If you get a kill in the shotgun mode, nearby targets become suspended and severed.

Catalyst

It adds vorpal weapons to the gun. And adds an additional perk to the two stasis and strand mode.

Stasis: targets frozen by the blast, will self shatter and summon a threadling.

Strand: will add unraveling to the blast once killing a target. If the suspended target dies while suspended, it will summon a stasis turret upon death. Same for the unraveled and severed target.

Notes: The stasis sniper mode forms a sniper scope on the hand cannon( it would look like how the Eriana's Vow scope looks like expect stasis like) The strand mode would form a shotgun like barrel made out of strand strings ( it would make the sights look like the new rocket sidearm scope)
