Skills

Skills have been modified slightly in order to merge redundant ones together as well as broaden the use of others. Another important change to note is that all skills cost 1 rank and you may only have ranks equal to your level, although if you put a point in a class skill you are granted a +3 class bonus to checks related to that skill; thanks to this change classes no longer multiply their initial skills x4, they merely get (base class number+int mod) skill points.

Appraise
In addition to determining the value of items, one can attemp an appraise check to identify the magical propierties of magic items.

Intimidate
Charisma penalties are added as positive modifiers to Intimidate checks as long as the character is some sort of humanoid or giant.
