IMO, some of the Origin Path options just beg for the character to pick up some Elite Advances to flesh them out. The basic guideline for Elite Advances is a cost of 500 xp, but that can be adjusted up or down depending on what the player and GM work out. Still, I'm wondering if there is a bottom limit. One of the examples shows a player 'bidding' 200 xp to purchase Trade (Miner) for his character. What's a good guide to assigning the xp cost for Elite Advances tied to a character's Origin Path?
What I'm looking at right now are xp cost suggestions for the following:
A character with the Child of the Creed background wants to start with Common Lore (Imperial Creed).
A character with Peer (Underworld) from Noble Born wants to start with Common Lore (Underworld).
A character with Decadence from the Vaunted background wants to start with Carouse.
A character with Logic from the Savant background also wants to start with Peer (Academics).
Should these Elite Advances cost 100 xp? 200 xp? 500 xp?
