Hi All,
From reading the forums, it seems like quite a few other people have decided to allow players to repeat a basic career, enabling them to increase specialisation in that career’s skills etc by taking another level of training/expertise etc.
However, one penalty that immediately springs to mind regarding this approach is that a player would forfeit the opportunity to take an additional career special ability card. To me, that doesn’t seem wholly in keeping with the theme of specialisation (at the cost of a broader skill/ability base) that repeating a career entails. I’ve therefore come up with a draft list of special abilities for characters taking a career for the second time.
In order to reflect the inherent specialisation of that career I have based these on the original special ability cards, the idea being that the character gains this ability in addition to the basic one as they would if taking a new career path. In each case, I’ve tried to distil what I thought the ability was saying about the career, and keep the second ability in line with that, even if this means that there is perhaps a lack of balance career versus career (which seems to be the case with the initial special abilities anyway). While some of them offer pretty beneficial effects e.g. a fortune die on all checks for a couple of skills, I like the idea of careers being a little more specialised and differentiated, particularly if someone takes the time to master that path.. which choosing it for a second time would represent.
This is just a first draft for my group and I would appreciate people’s thoughts and suggestions, especially re: balance and how well these fit into advancement more generally. I'm pretty new to WFRP so any useful pointers would be helpful. Thanks.
