I didn't see this while searching, so if this has already been addressed, my apologies.

I recently picked up the Inquistor's Handbook to give my RT group some more toys, and I'm noticing some serious differences between similar or identical weapons between the two systems. Is there some common conversion for each of these, or is this just a fudge-worthy issue.

If you allow the DH item in your RT game, allow it as it is listed in the RAW.

The only items I'd suggest refusing are:

- Items with obsolete rules, like the IH force field devices.

- Items where there is a very similar item in RT. For example, ammo backpacks (RT core and Ascension) and Force Weapons (IH and Into The Storm).

Some things to consider about an items rarity:

- DH items have their rarity listed for within the Calixis sector. Outside it, where Rogue Trader mostly takes place, the rarity might be different, usually Imperium produced items will be rarer, Xeno produces will be more common. Some might simply be unavailable.

- Some items don't have a rarity listed, instead they have things like Tech-Priest only. So you will need to decide it for yourself there.

- Early DH books don't have any rarity above very rare.

So don't be afraid about altering an items rarity.
