I love this gun in PvE, but in it's current state it is almost the same as the legendary gun Timurs Lash. I suggest adding a one property to the first curseperk: each precision shot to a minion of darkness increases the damage of the next precision shot. Damage buff add up until the very last shot, reloading and shooting in the torso resets the buff. The increase in the damage must be such that this pistol could be at the level of other exotic guns, but to uphold the principle of skill and accurate shooting.
