Bardic Knowledge is not used in TOEE. The Bard simply does not have it.
The use of Appraise skill depends on wich patch you have.
Unpatched :
The merchant check the skill of the PC currently talking and use that to calculate prices. You have to put all valuable items in the inventory of the PC with the highest skill to make good money, and that makes bartering take a long time.
Atari's Patch:
The merchant checks the skill of ALL the PC's, and use the higest. Bartering is quicker and you get the best price depending on skill.
You don't have to move items around.
The Appraise skill IS NOT useless, it's very valuable. Rouge & Bard have it as class skill and can get a high score in it, but i let my Wizard take it cross-classed since he's got the highest INT score, and summons a 'Raven' familiar (+3 on Appraise skill). At lvl 10 my party have more than 500 000 gold ALL the TIME ! (I make and sell magic items too).
Always have one PC take Appraise as high as possible, then you don't have to pick up worthless loot like 'black leather gloves' and such.
The increase in prices is at level 1 around 30-40 % from min/max skill score, later you get close to 100 % increase in prices. Don't go adventuring without an Appraiser !
Co8 patch let's you use 'Read Magic' on potions. This is nice, but i normally let my wizard make 100 scrolls of Read Magic. They cost 6 gp and 0 XP ta make, so now i pay only 6 gold to identify scrolls or potions. I do this because it's much quicker than traveling to town to rest and to free up inventory space. It also let me carry on longer while in the dungeon.
For 'Identify', Craft Wand is the way to go. It has 20 charges and is very cheap to make. If you have pen & paper at hand you can 'track' the wand of 19 charges and sell it at full price to a merchant. (You can do this with all wands to save gold).
To make a lot of money:
Buy a masterwork weapon or use one of them stupid daggers +1 you find so many of. Enchant it all you can. Generally, if you spend 30.000 gold on it you can sell it for 100.000 gold !!!with a good Appraise skill.
Have Fun & Porsper
