In my last post I forgot to include something of vital
importance, at least for demi-humans. :)
IMC, it is an accpeted fact that demi-humans do not
think like humans. Specially in case of dwarves and elves.
Based of this, it is general rule( not only for BR
but for all games I now play) that dwarves and elves require
double the normal amout of Xp to level advancement.( normaly
we use triple for elves).
This cause problems in a troupe style play( because of the
level difference), but works very well on a extended campaign(
we have a BR that, in game time, goes for 150 years, so the elf
is still the same as the begining, and the humans are on their
fourth or fith generation.)
