Alertness allows characters to gain a +1 on their surprise check when they make a successful proficiency check.

Blind-fighting

Blind-fighting allows characters to suffer less penalties for fighting in darkness; although he no longer has any AC penalties for melee, he still receives the normal AC penalty (+2 or +4) vs. missile weapons.

Darkness	Normal			Blind-fighting
	Attack	AC	Movement	Attack	AC	Movement
Moonlight	-1	+0	Normal	-1	+0	Normal
Starlight	-3	+2	Normal	-1	+0/+2	Normal
Total Darkness	-4	+4	1/3	-2	+0/+4	2/3

In addition, special abilities normally lost in darkness are retained, although at half efficiency.

Blind-fighting also allows characters to suffer only a -2 penalty to attack (as opposed to -4) vs. invisible creatures.

Juggling

Juggling allows characters to entertain and perhaps create diversions. A check is made when trying spctacular tricks.

Juggling also allows characters to try to catch items thrown to harm him (such as daggers or darts) by attacking vs. AC 0; if he fails, the character automatically suffers damage from the weapon instead of catching it.

Spellcraft

Spellcraft allows characters to identify spells being cast (wizard specialists gain a +3 bonus to identify magic of their own school).

Magic to be Identified	Check Modifier
Spells	Normal
Magical or magically endowed constructs	½

Tumbling

Tumbling can be used for entertaining with somersaults, handstands, flips, etc.; however, tumbling can only be performed with light encumbrance or less.

Tumbling can also be used to improve AC by 4 against attacks directly solely at the tumbler in any round of combat if he has initiative and forgoes all attacks that round; or, in unarmed combat, he can improve his attack roll by 2.

Finally, Tumbling allows characters to suffer less damage from falls on a successful proficiency check as shown below.
