Paladins get a special Detect Evil ability (accessible through crafting menu).

Stealth is more effective in some areas (such as dark caves) than it is in brightly lit rooms. A PC that is transluscent has been heard only, not spotted (this is default, but bears repeating: although difficult to enforce, we ask that people do not definitively identify characters who have only been "heard").

There are various damage modes (subdual, sparring, and full damage) all accessible through the crafting menu. Familiars/Companions/Summons should be on the damage mode of their master.

Ability Changes:

"Feeding" your animal companion or familiar can only be done once every fifteen minutes, and will heal 1d4 hitpoints.

An animal companion or familiar's master will lose experience and d6 HP when their associate dies, as a result of mental anguish from the close mental bond between the two. The loss of a familiar incurs 100 XP loss; the loss of an animal companion incurs 200 XP loss.

Death Domain shadow avatar will not appear before level four. The avatars have also been modified to be appropriate for each particular deity.

Turn Undead has been modified to allow for commanding as well as destroying. Specifically,

Clerics with an evil alignment will command the undead. Clerics with the Good domain will command good-aligned outsiders. Clerics with the Evil domain will command evil-aligned outsiders. Clerics with the Fire domain will command Fire Elementals (likewise for the Earth, Air, and Water domains).

Pickpocket has been disabled for use against NPCs and PCs. You can still use it for scripted pickpocket rolls (such as in in a scripted quest) or in a DM situation (such as stealing a key from a NPC).

Use Magic Device requires a DC Check of 15 + spell level to successfully use a wand. If you do not succeed in your check, a charge is not expended. Some DM-only loot may not work this way.
