I have discussed with some of you in the past the possibility of 'buying' certain abilities with experience points and I think I have worked out a system. I would like some feedback from you all before I allow it. I would use the geometric progression 1000, 2000, 4000, 8,000, 16,000. You could buy either a feat or 5 skill points. You would still have to meet any prerequisits for the feats and be limited to the normal maximum numbers of skill ranks based on level and class/cross-class status. Thus, the first time you buy a feat or bundle of skill points it would only cost you a 1,000 exp. A pretty good deal that I expect most players would avail themselves of. The next one would cost 2,000 exp., that is still a good deal. The 3 such purchase would be 4000 which is getting pretty expensive and I expect would be a less popular choice. To make a 4th such purchase would cost the character 8,000 exp., which would be a total out lay of 15,000 exp. just for extra feats and skills. That would be really limiting the character in other areas. A final such purchase would cost 16,000 exp and I don't expect anyone would make that many as it would be as costly as the jump from 16th to 17th level, but I'll leave the option out there. You would not be able to spend enough experience points to drop you to a lower level or take a negative total starting out. Does anyone see any serious balance issues with this? I expect everyone will spend the first thousand and likely the extra 2000 for a second such bonus, but that is about it. If you were working toward a hard to qualify for prestige class or maybe fighting style perhaps it would be worth it to go to the 4000 level, but you'd be out a total of 7000 exp. and that would almost certainly hamper you more than help you.
The result of these changes would be greater access to feats and skills, which is always fun and increases the power level of the characters slightly. The other result is that it will be easier to get access to other feats and to prestige classes.
Should we consider allowing anything else like maybe +1 to saves or +1 bab or some number of hit points to be purchased as well or are those things adequately covered by existing feats.
As always the DM will have final say in all purchases.
