I really, really need some help here guys.
A friend and I have been debating a few things back and forth and neither of us can come to a conclusion. Here are the topics that we are requesting your insight on:
When I start a new character at Wiz 1, he begins with a spellbook with all cantrips and a number of 1st level spells equal to 3+ INT mod. This represents his time in training, comonly as an apprentice.
When my Rog 1 decides to take his second level in Wizard, does my Rog 1/Wiz 1 get the free spellbook? Or does he have to pay (wow!) 100g per cantrip (there are 19 in the PHB alone, btw) and another 100g per 1st level spell contained within the spellbook? If this is the case, that is a crazy amount of money to lose (about 2,500 gp) for not picking Wiz at first level. I'm thinking those extra skill points and a couple of HP's come at a high price. Also, I understand that you don't "have" to buy all the spells, but that's beside the point.
OK, this one regards clerics and domain spells... A party of mine ran into a drow cleric with her patrol at around 12th level. During the fight she cast Chaos Hammer. Then she cast Chaos Hammer. Our Aasimar Paladin wasn't looking so good, so she cast Chaos Hammer... again. I'm about ready to choke someone by this point! Isn't this a domain only spell (Chaos 4)??? Of course, replied the DM. She mem'd it as her 4th level domain spell and then heightened it into her 5th and 6th level domain spell slots with a metamagic feat. I cried foul, but I still haven't found anything concrete saying that she couldn't do just what she did. BTW, we nearly TPK'd from an equal EL encounter, so I'm thinking this tactic is questionable, if it's legal at all. :\
Any comments or insights will be greatly appreciated. Anyone who can provide references to back up their reasoning will be even more appreciated!
Thanks In Advance,
