Regularly an Inquisitor is unable to do the Mist Assassin gig, without a mist type spell available to them. This build gets around it by being Moroiborn Dhampir and using their SLA, refueled by the Recharge Innate Spell. Early levels seem as if they will be slow but level 4 onwards seems good. Still a skill monkey non the less. Shooting without Sneak Attack is not ideal but, unlike some Mist assassin builds, it does not cripple them.

At 4,500 gp the Saltspray Ring might be more party friendly [10' radius vs. 20' from you] than the obscuring mist, as well as more uses per day.
You did not mention how you et the revelations. I had to look that up.
They come from the Ravener Hunter's Charged by Nature choosing the water mystery.
