Basically type something in like "nova visual" or "shadow" etc then scroll down to uncatergorised spells. Drop down that list and scroll to a spell you like. Once you find a spell you like hit on it, now the link will be something like: http://www.thottbot.com/s39733 Now with this link you simple get the numbers on the end, and in WoW type .char learn (these numbers) or .learn (Numbers). You should always test to see if the spell works before adding it to a script, and if it still doesn't work on a npc then your probable triggering it wrong (needs to be casted on player) and such like that. Note that spell 5 is disabled on npc's.
Good luck!
