One of things I like about 5th is that it brought back this first edition feels. There are lots of places in the 5th ed rule books that say story > rules. If the story is good and the DM approves it works -- especially with character background. Archetypes should be flexible. Astarian's master made him a seducer / scavenger: after Astarian brought Cazador the beautiful people to feast on Astarian had to go back to their dwellings and pilfer their jewels . . .

He's had 200 years, plenty of time to pick up some new skills.
