Is it too late to join in on this? Bloodborne and I have been through a lot together.

And I do have a question, regarding the Milkweed Rune in the DLC that turns you into [s]cauliflower[/s] a Lumenwood creature and the Beast Rune. Will it be possible for characters to obtain those later down the track? I'm just asking because I need to prepare myself mentally if one of the characters in the roleplay is going to be a walking talking vegetable.
