d) I had a player build a PC with some stuff, that I couldn't figure out where it came from (it was one of the ones I listed as SRD below) and HL allowed him to take it. So I built this list of things that appear to be allowed when the source isn't checked. I've got comments below this list also.
Monk of the Empty Hand, Zen Archer, Urban Ranger, One-Way Window (APG)
Academy Graduate, Arena Blood, Child of Shadow, Knack for Magic, Merchant Tongue, Steadfast Loyalty, Student of Nature, Suspicious Eye, Water Rat (Savage Tide)
Ability Focus, Awesome Blow, Craft Construct, Empower Spell-Like Ability, Flyby Attack, Hover, INArmor, INA, Multiattack Multiweapon Fighting, Quicken Spell-Like Ability, Snatch, Wingover, All races (Bestiary I/II)
Wooden Armor (APG)
Shoanti War Paint Black (Pathfinder 10)
Oculus of Abaddon (Pathfinder 33)
Eyes of Petrification, Gauntlets of Incredible Dexterity, Magi Staff of the Necromancer, Shrouds of Disintegration (SRD? or other?)
Sliding Axe Throw (Dwarves of Golarion)
There doesn't appear to be a check (source) for some of the pathfinder things like #10 and Savage tide, so no way to exclude that material?
The allowing of Bestiary races and feats isn't that big of a deal, it just is inconsistent with the other books like (APG.)
Not all of these report where they are sourced in the text, especially the ones I've listed under SRD. A number of those I couldn't find what book they appear.
