Gambling/Gaming (Int)
Class skill for rogues, bards, swash-bucklers, and priests who worship gods of luck or gaming
This is a basic knowledge of what games exist and what the rules of the game are. Luck however, may still be required to win.
Hypnosis (Cha)
See Expanded Psionics Handbook
Knowledge (Forbidden) (Int)
(special. In an evilish way)
If you have occasion to earn a rank in this, I will tell you what it does. You may not put ranks in this skill without prior GM authorization.
Knowledge (fortune-telling) (Int)
(class skill for those who have all knowledges as class skills)
Knowledge of divination techniques and ceremonies. This does not provide magical diviniation, merely a means to interpret ancient ceremonies.
Knowledge (monster lore)* (Int)
(class skill for all)
This skill does not help you identify the monster. It does however let you know various cultural practices of different monsters, their languages, ceremonial rites, how not to insult their grand vizier, and so on.
Knowledge (runes) (Int)
(class skill for those who have all knowledges as class skills)
Knowledge of the esoteric meanings of some of the ancient rune languages.
Knowledge (undead lore)* (Int)
(class skill for those who have all knowledges as class skills and clerics)
This does replace knowledge(religion) for identifying undead and knowing the means of their creation. There are so many religions and pantheons out there that knowledge (religion) became a bit too big of a field of study.
Martial Lore (Int)
See Tome of Battle
Memory* (Wis)
Pretty much self-explanatory. With a successful role, I'll let you do things like accurately repeat a conversation, sketch a rune, redraw a map, accurately make a map of a room you passed through, etc…
Truespeak (Int)
See Tome of Magic. Except their math sucks, so ignore the x2 multiplier.
