I also plan on adding a certain ToB-only NPC when I get there.

TIA

Yes, add him for a back up spell caster. He's very overpowered though.

Everything looks in order.. And yes, he's overpowered, but I will bet $50 that Krunchyfrogg dies at least twice with that mod installed.

Now, are you getting it for the 'familiar', or was that just the deciding factor?

I thought that the familiar was only for Jan? Krunchyfrogg doesn't have Jan in his group.

It was a joke, relating to a PM back-and-forth.

I'm actually having problems installing this mod, and considering all the stuff I hear about him being overpowered, I'm considering giving up on the idea of having him in the party.

I guess it's coming down to this: Do I need a backup Mage? The party is small (4 total), and I don't know if I really do need one. Also, when I reach ToB, I plan on adding the NPC that shows up there. He could be my backup Mage, but I wonder if I'd ever get his Fighter levels reactivated, even in a 5 person party.

If you have a F/M in your group, then he won't be your backup mage. On the contrary, the rest of the party will be a (very rare) backup for him. :D

He can do everything alone.

Ok, that's not fun in my book, so I'm going to drop that idea.

Do I need a backup Mage, or is Imoen enough in a 4 person party?

A backup Mage is always very good to have around--getting off a Greater Malison and an Emotion (and a Greater Command from your Cleric) in the same round spells death for the vast majority of enemies. More Wizards in the party means that you Lower Magic Resistance faster, you tear protections down faster, etc.
