Min/Max Boards

Whenever the party tries to sleep in an inn, throw loud raucous parties that keep them up all night.

Whenever the party tries to buy a magic item, kill the person who's supposed to sell it to them so the party never gets new items.  Or kill the person who did sell the item and make sure word gets around, so no one will sell to the party.

Hire the town drunk to put "the moves" on someone in the party.

Frame the party.

Start nasty rumors about the party.

Use "Bestow Curse" on waiters so the waiters don't notice the party.

Raise the dead on any big bad the party just killed.

Take the credit for any big bad the party just killed.

Slip drugs into the party's food/drink.

IIRC, when you dual-classed, you were only about 1 level lower than someone who didn't dual-class.  E.g. you could be cleric-7/wizard-7 when someone else was wizard-8.  Kind of like playing a gestalt instead of non-gestalt.

What book again, please?

Secrets of Xen'drik, p157

So you need a Feat, 36,036gp, and five 4th level Slots to pull that off.

Wouldn't that be 36,036gp and (a Feat OR five 4th level Slots)?

If you want a more humorous reason, consider the entry under "Half-Celestial"

To carry out their responsibilities, celestials sometimes spend
great amounts of time in mortal realms. Being devoted and kind,
they occasionally fall in love with mortals: humans, elves, unicorns,
and similar creatures. The objects of celestial affection are
never evil and are always intelligent. They always return the love
of their immortal paramour and willingly conceive the child, usually
caring for it since the celestial has other duties.

In exchange for a plane-shift back to the material plane, the PCs are charged with baby-sitting.
The PCs watch the kids 5 days a week, and have weekends off.  Or the PCs can do what they want, but have to be ready to respond when the celestial calls.

You probably already have them, but the DMG 3.5 has some tables in it too.
p 44 - One Hundred Adventure Ideas
p 78 - Random Door Types
p 82 - Random Traps by CR level
p 94 - Random Weather
p 129 - One Hundred Traits

I used to use the one hundred traits table a lot when I had an unexpected need for a talkative NPC.  Helped me not to fall into default NPC mode where they all have the same personality.

And let's not forgot the old mixing potions table from D&D 1.0(?)

Depending on the monstrous humanoid, there may be a "savage species progression" for it.

Never mind - I got it working

On a related note, if you google "wayback machine", it takes you to https://archive.org/web but if you use the url www.archive.org it takes you to a different page.  The first seems to only take you back to 2014, the second takes you way back.

How about a Glove of Storing?  Storing and retrieving the shield would be a free action.  I think there's a similar but better item in the MIC.
