Just the Normal ones.

the uncanny ones counts for the trophy, I got the platinum trophy on the base game with half of the weapons on uncanny versions. hope this helps

Both of these replies sucked. You can get the achivement with any combination of all the weapons. So if you have a lost version of one weapon but the normal version of all the others, it's still fine. Mix and match how you like.

"Mix and match how you like" is exactly why the first two replies were great. You put them together like a jigsaw. See what happens when you all work together and definitely don't be horrible for no reason?

You can have any variants, you just need to have one

Standard

they exist in your game so that invaders and whatnot can use them but I don't think you'll be able to use them yourself

If it works anything like ds3, then if you get a buddy with dlc and the weapon he can drop it for you

You actually cant drop items for other players in bloodborne

You have to have the DLC and acquire the standard version of the weapon in the dlc before they will appear for sale

Yes, because you can equip it and it does damage

*To get the achievement

I believe it’s one character, same as the base game

Yes you do need all firearms

Some say Kosm

Do you hear our prayers?

Or some say kosm

As you once did with the vacuous Rom

grant us eyes, grant us eyes

Plant eyes on our brains

Just buy it, it's only $10
