Enchant bars (silver, electrum, gold, plat, etc) is a chanter only spell - you get silver at lv 8, elect at 16, gold at 24, and plat at 32. These spells are available from the guildmasters who sell spells at their guilds as well as POP library. You can also get mass enchant spells (instead of 1 bar at a time, you can do either 4 or 5 bars - cant remember which off the top of my head). You can work on JC without enchanting, but you will not get the magic items which make this attractive in my opinion. Note that it is an expensive craft as you lose components on a fail (plat bars are over 100 PP each plus jewel) and only get the component costs back on sale to vendors assuming above 125 char. Look at the links on this site to JC for some excellent tips on building this skill as well as recipes for making items and trivial levels (point where skill does not go up for success which is automatic here). Good Luck
