Here is a partial list of the changes and additions I'm going to use in my upcoming campaign if and when I ever actually manage to run it.
* All skills are class skills for every class. Classes remain balanced, though admittedly in a weaker sense, by the number of skillpoints available to each class.
* Hide and Move Silently are combined into one skill, Sneak. Any class feature or racial ability that granted the Stealthy feat now grants Skill Focus.
* Listen and Spot are combined into one skill, Perceive. Any class feature or racial ability that granted the Awareness feat now grants Skill Focus.
* All multiclassing limits are abolished, within reason; paladins and monks are restricted only by alignment considerations, but wizards cannot multiclass between different specialist variants.
* By default, D&D allows a character to qualify for a feat or prestige class by possessing a magic item which grants the relevant ability. This rule is abolished.
I'm not sure which races I want to use in the setting. Humans, aasimar, genasi, and tieflings for sure, and definitely some races from the
Expanded Psionics Handbook, but the exact list is undefined.
* The celestial, demon, devil, and elemental bloodlines from
Unearthed Arcana will be available. Planetouched races will not be permitted to take bloodlines, even of different types.
The following classes from the following sources are available:
*
Player's Handbook: Cleric, druid, fighter, monk ranger, rogue, wizard.
*
Complete Book of Eldritch Might: Bard, sorcerer.
*
Expanded Psionics Handbook: Psion, psychic warrior, soulknife, wilder.
*
Arcana Unearthed: Champion, unfettered, warmain.
*
Unearthed Arcana: Totem barbarian (Ape, Dragon, Eagle, Jaguar, Serpent, Wolf), cloistered cleric, urban ranger, thug, wilderness rogue.
*
Complete Divine: Favoured soul, shugenja, spirit shaman.
*
Complete Warrior: Hexblade, variant non-spellcasting ranger.
*
Ghostwalk: Eidolon, eidoloncer.
There's a long list of prestige classes that I don't think anyone cares to see.
* As suggested by the classes entry above, I will be using the death rules from
Ghostwalk. I prefer this solution to fudging for the sake of keeping PCs alive before they can afford raising magic, plus, it's weird and cool.
* Metamagic feats will not increase the level of the spell, but instead allow three uses per day per the rules in
Unearthed Arcana.
As a general rule, I will allow players to bring in any feat, spell, or class that fits the theme of the world, if they accept my alterations to it where necessary. One overriding automatic rule of exclusion, however, is that the world has no knightly or chivalrous orders - so paladins and other knightly archetypes are absent. Champions fill the "holy warrior" niche, and fighter-types fill the "mounted warrior" niche.
