Browsing the rules on career transitions a question occurs to me.
P 38 WHF01
"Finally, it’s important in case a character ever decides to re-visit a career they previously played. When returning to a previous career, it is always considered a compatible transition – so only one advance is required to move back into a career a character already has been in. This applies even if the character’s current career and the previous career would otherwise be considered incompatible."
"Reiklander characters have a special racial ability called Adaptable. This ability reduces the cost of career transitions by one advance. With this special ability, Reiklanders can reduce the transition cost to zero, which may allow a Reiklander to move directly into a compatible new career for no advances."
So in the RAW a Reiklander can transition careers freely (barring GM fiat).
My question is, can a PC transition from career A to career B, then return to career A to transition to career C, taking advantage of a compatibility of A to C and the career A dedication bonus.
For example. A Reiklander PC completes the Student career and takes the dedication bonus. He then transitions to Mercenary (-1 compatibilities, -1 for dedication, -1 for Rieklander = 1 Advance). He does not complete Mercenary before wishing to transition to Dilettante. From Mercenary to Dilettante would be 2 Advances (-1 compatibilities, -1 for Rieklander = 2 Advances). . Transitioning back to Student (0 Advances) and then to Dilettante would be 0 Advances (-3 compatibilities and -1 for Adaptable).
This appears to be legal in the RAW. The only issue appears to be if multiple transition paths out of a career is possible - there is only one line for career transition. So perhaps only one career exit path is allowed. The PC in the example would need to transition from Mercenary to Dilettante. However, this is not explicit in the RAW.
