Brainstorming a setting for a Tier 4 classes only game

[Gavinfoxx]

For Adepts, I'd combine the benefits of Adept and Religious Adept, and maybe a few selected spells from Urban Adept, and pick which domains are readily available for them to pick. Then I'd make the feats:

Scribe Scroll
Inscribe Rune
Craft Magic Arms & Armor
Craft Wand
Brew Potion
Craft Wondrous Item

the main feats available, and then figure out what these Religious/Urban/etc. Adepts of, oohhhhh, 13th level and below can make with these feats can make, and those are the magic items available in the setting.

Or possibly even remove Craft Wondrous Item and Brew Potion, and have the main crafters max out at Adept 5/Runecaster8 (for Improved Runecasting), and have Wondrous Items be those legendary items of yore.
