Ravenous Bugblatter Beast of Traal
Does anyone have some basic rules they're using that takes into account some sort of training and cost associated with level advancement that is reasonable, has flavor, and is still fun without being cumbersome and feeling like your PCs will be taking long sabbaticals every other game?
Absolutely! I *require* characters to level to go through a lengthy set of serious, hands-on training. And not in controlled circumstances with little repercussion, but rather under real-life (for them) situations with potentially deadly outcomes. No trainer or classroom can compare.
In return I grant them learning chits and they can not level up until they have accumulated a sufficient amount of them. I increase the amount needed every character level as well.
I call these learning chits: experience points.
