Races
- -Non-biological aspects removed from race
-- Rolemaster/HARP style adolescence/cultural packages that can be added to race providing ranks in common skills for that culture
Occupations:
add Occupations similar to d20 Modern, but have them grant a few bonus ranks.
Classes
- -Reduce the power of spellcasters at higher levels to balance with other characters (e.g., have them cast the equivalent of 6th spells at 18th level).
- -Classes w/ talent trees and bonus feats instead of set class abilities
- -Classes receive a minimum of 4 skill points
- - Classes don't provide automatic proficiency with armor and weapons, sneak attack, etc. Instead, a first level character gains a number of bonus feats based upon their initial class and is given a bunch of class feat choices (including armor and weapons) from which to choose those bonus feats. This prevents from multiclassing characters from dipping to acquire proficiency in all armor and weapons and requires them to gain such proficiency over time.
Saving Throws:
-- Characters use the same save progression, but receive a saving throw bonus (or bonuses based on their initial class).
Feats
--Replace Improved Unarmed Strike with Brawl, Combat MA, and Defensive MA feat trees
--Add Several Divine Feats (no persistant)
-- sneak attack, rage become feats.
Combat
- - Class based defense
- - Damage Track ( Currently, I use fatigued at 50% hit point loss, Exhausted at 75% hp loss. At 0 hp, use death and dying rules from Unearthed Arcana)
