Hey Loki - with the Ninja, any spells will increase Alchemy as it is the only spellbook he learns them from. Also you can increase it by mixing together potions/powders you find (do them one at a time rather than in groups, each seperate mixing helps raise it). The best spell to raise Alchemy quickly if you don't mind a "practice" session is knock knock; use it repeatedly on the bank vault in Arnika under the jail, just don't make it powerful enough to actually open it up or you'll get busted [img]smile.gif[/img] Cast as many low level ones as you can on it, then rest to recover the spell points and keep going.
Your Bishop is more complicated because he knows all 4 spellbooks. When you cast spells that *only* in the mage's spellbook, that will raise Wizardry. Or if Wizardry is higher than his skill in another book(s) that a spell can be found in (for example, Light - it's in mage, alchemist and priest spell books), then that spell will raise Wizardry too. So if he was 23 Wizardry, 20 Divinity, 20 Alchemy and cast light, it would raise his Wizardry skill because it's the highest. It would never raise the other two. If Divinity were 25 though then it would raise Divinity only.
Hope that helps
