17) The PCs lose their mercenary charter (due to the new king reviewing all charters), the document that allowed them to carry use and own armor and weapons, and magic items without being nobles or ranking members of the Mage's Guild.
The kings authority on this matter is backed up by several dozen high-level clerics and wizards, who have gathered lots of information on the PCs and other targets.The king doesn't like mercenaries that are too heavily armed and the PCs qualify.

The DM better hope the players go along with it or the DM will need new players too

That might be a good start to an Evil camp[aign though, the king who you helped betrays you so almost powerless you go gunning for him

10 levels later you trade the soul of his first born to a baatezu for some new items

37) The dreaded spellgaunt, from the MM2.

38) Making a character panicked or stunned when they're above a destructive force (lava, negative energy plane, pool of acid, whatever- they drop whatever's in their hands)
