The build looks good to me.  You're not min-maxed, but your character definitely looks solid.  You're not skimping on skills in favor of combat domination, which I find commendable.  I politely disagree with Cymbel regarding the Impostor background package, but understand her reasoning.  The Inquisitor Handbook backgrounds are also quite nice.

I think for 400 thrones you'll be able to field survivable equipment, but get the most value for your buck on each purchase.  And Cymbel is right: using any gear that is blatantly Arbites issue is going to give you away in an infiltration assignment.  The Cyber-Mastiff could also be a huge tip-off, but could be managed with some creativity.

You've got my stamp of approval (Which is not worth the bytes of processing power required to type it)

Thank you Cymbel and Id for your help and advice.

@id, I guess it is indeed not min-maxed, far from it. My days of min-maxing are really behind me. It is long gone the time where I could spend weeks in getting the most of every supplement available on our Rolemaster, basic or DD campaigns. Now I barely have the time to skim through the books and understand the rules of the game, the perks of growing old. Sic transit gloria mundi…  

@Cymbel, I see your point for the backgrounds. And Justice not Law (vigilante background), and the Callyxian Pattern Kilings might be fitting and/or more efficient on Xp basis. I'll give it another serious look.

Reguading the money allowance, my GM is just trying to be fair, eventhough I begged and cried to have more money. The other players received approximately the same amount during play and received as a gift from their inqusitor, ours starting Sunday,  a single item worth 3000-3500 thrones (the psy sword for the psyker for example).

Are the RT books compatible with DH ? Or does it need GM approval ?

You're welcome, Sang de Poulpe.

Yes they are compatible, though they change the power balance.  It's a considerable change, in my opinion.  You should get GM approval since they are not considered supplements for Dark Heresy, although the rules are compatible. 

We never integrate equipment from other Fantasy Flight Games lines, even W40K related games, into our campaigns.  It's not necessary, and I don't imagine it would enhance the roleplay experience.

My main issue with the Impostor is that it lends itself towards you being a con artist or you assumed the name/role of the acolyte you are playing (at least how I see it), but you can always ask the GM to change the fluff as well, but I am glad you are giving the others a second chance, the vigilante one is a fun one for a lot of PCs

As for RT gear, it is 99 times out a hundred compatible, but a lot of it can't really be used in DH, because the cost would beggar acolytes or it is near unique rare xeno/archeotech, would stick out like nothing else or just is for a purpose that DH PCs never would use. That said, some of the new melee weapons, guns, gear and ammo is stuff that you could really use in DH and adds fun choices (Just look at the shotgun ammo in HosAcq, DH fans have been wanting shotgun slugs for the longest time, same with several other rounds), best way to set an availability cap for items you can choose from, everything else is with GM permission, but it is worth asking, some of the stuff is just too essential to not use.

For further gear help, can you tell us which items you are selling and what kind of gear/weapons/armor you want?

And for cash, look at the armor and weapons of other PCs, see how much armor they each have and how strong their guns are. If they are not very well armored or heavily armed, then best to fit into that power level, however if they have all mesh/light carapace and wielding fancy guns (not a generic pistol, but a Hecuter or a Carnodon for example) then you are right to ask the GM for a better hands up (and at least 1:1 selling starting gear)

The ranks of Detective-Espionist within the Adeptus Arbites are often impostors within their duty location.  Posessing that background, especially as a rank 5 arbitrator, seems to fit very well within the existing lore.

Hello all,

A few things, I played yesterday and it was really fun. Thank you for all your advice it was really helpfull.

I finally went for the Justice, Not Law background as it was a bit better xp wise, IMO.

As for my gear, I went for a combat shotgun (augmented), a combination of flak and mesh armour, and utility gear.

By the end of the scenario, we looted several bolt guns, chain weapons and other stuff. Money shouldn’t be a problem at least for buying ammo ;).

I had one blazer shell and it hit. Those things are really usefull for putting enemies out of combat. I might buy a vanaheim shotgun, I am in love with the semi auto function of my combat shotgun, I guess full auto is even better.

I am considering buying the talent for pistol training bolt. 

Small question, is there a selection of talents to make sure I can stay in PBS range ? For the two combat we had I only got one chance to use it. The first time was because enemies went to melee and the second as enemies were shooting us with bolt guns and had chain swords and didn’t feel like leaving cover or getting close enough to get hit by the chain weapon.

Any advice on that? Or maybe I am doing something wrong wich is more than possible.

Sprint I suppose? It is tricky to get into the 3m range, but not get into melee, which is what makes shotguns a mixed weapon, on one hand they can rape on short ranges (which is often when you need it), but except at FAR ranges they still do decent power. Plus they are amazing with the sheer variety of special ammo they can use (especially if your GM lets you have some of the fun stuff from ItS, HA and so on), Blazers are an amazing toy as you saw and can singlehandedly change how a combat is going (FLAME is a powerful weapon special ability, as well as having a cone that covers multiple things), with stuff like Slugs, Cryptus Glass Shells, Flechette Shells, Toxic Shot, Gas Rounds, Bolt Rounds, Inferno Shells, Acid Shells (OP but awesome), Executioner Shells, Snare Shells, etc.

Later on you will be rolling with only Flechette Rounds, Slugs, Inferno Shells and so on as your normal ammo and your trusty shotgun will not let you down :-)

On the Vanaheim, it becomes a visibility issue. Combat shotguns may stick out a bit, but heretics will have them too, looted from Armories and what not. A vanaheim belongs in the class of the Nomad Rifle, Cadence Spectre, Carnodon, Hecutor and other rare specialist/finely crafted guns. They are not normal and stick out. But if you think it won't (or keep it as your assault weapon for raiding places), then don't worry. But yeah, in terms of DH and Top End shotguns there are the versataile and powerful vanaheim, with lots of ammo, full auto, laser sight and free nice bayonet, the OP Arbites XBAWX HUEG shotgun, the way underpriced for all the awesome it can do Ironclaw shotgun and the solid fun Arbites Persecutor Combat Shotgun (+5 Range, +2 Shots, Reliable and can be used as a Shock Staff in melee compared to a normal Combat Shotgun).

Not sure if it has already been mentioned or not, but if you want to be an infiltrator of heretical gangs and cults, then you might want to give the Malifixer alternate career path from the Book of Judgement a look. They pretty much thrive on this kind of thing, and can spend years undercover before yurning on the cult at a moments notice.

The problem with this for you is the fact that a Malifixer has to be a scum class, and they tend to work for heretics themsleves. If you were playing this then you could have been recruited by the Holy Inquisition, and decided to use your acquired skills and expertise to do the Holy Emperor's divine work.

Just a thought.
