Sewer Rats Are People Too

[wykydtron]

Hey! I'm running a sole campaign for a friend. It's a really, really beer and pretzels campaign. As, in almost anything goes so long as its entertaining. An example might be playing a song on his guitar to make a new spell that causes a tidal wave of sewage to knock down the zombie that were chasing him. I decided to make a 100xp cost per level of spell type thing.

Anyways, I've had very little dming experience and was wondering if anyone else has done this campaign. Or if anyone has any advice or ideas for monsters, spells, locations should speak up. All comments welcome, the stranger (as I'm about to send him into "The Monster Lab" to clear out something) the better!

Sorry about rambling, I just figured more info about the complete unseriousness of this game. Also any advice about making sure the spell thing doesn't get broken (I understand that may be difficult). I'm not changing the spells per day, just what you can do with them. Dm's descretion.

Here's the link to where I found the idea, very detailed and interesting.
