Thanks for the ideas folks! Keep them coming
Here's what I have so far. Please rip it apart. My players are good at playing in the spirit of the game, but new players may tweak holes I can't see.
Note: I won't give exp banks to starting characters. They have to earn exp in order to spend it. Also, what works for one side works for the other. I figure I can use this to give BBEG's some added punch with extra feats.
Feats:
General feats: 100 x chain position x character total ECL
Item Creation feats: 200 x chain position x character total ECL
Metamagic or special feats, such as feats that improve spell like abilities: 300 x chain position x character total ECL
You must meet all prereq of a feat before you may purchase it.
PS: chain position means the feats place in a feat chain. Dodge would be x1, Mobility x2, Spring Attack x3, etc. feats that can be taken multiple times, such as Toughness, are considered feat chains when purchasing.
Skills:
Class Skills: 25 x new rank
Cross Class skills: 50 x new rank
Special Skills, such as psychic skills or those that produce magical effects:
100 x new rank.
You cannot use purchasing to skip ranks. Each rank must be obtained in order. You cannot purchase more ranks than your level limit.
In both cases, you cannot reduce your character level to purchase feats or skills. You may 'hold' exp for later purchase, but this exp cannot be used for level gain later.
I'm hoping that, given the hinted level requirements for PrC's (BaB, Power points, Base skills,etc) players will offset their spending to help speed up their level gaining. Those that don't plan on taking PrC's would have to curtail spending, or end up dead when they face opponents the other players are better prepared for.
