Probably Bad RPG Ideas

This is one of the most powerful monsters in 3rd edition!

The reason the party can't keep rerolling checks is because skill checks are an in-game non-renewable resource. Skill miner spend long hours digging them out in the mines.

My personal headcanon is that there's a Power Word for every possible state a person can be in.

Reverse of the usual pirate campaign: the party are stuck on an island and must deal with the assorted strange types who come to dock there (undead sailors, illithid brain-trawlers, smuggling gangs and spy rings making dead drops, treasure-hunting kobolds, the snurge, etc). Only at the very end do they amass enough ship parts to set sail themselves, after battling the antikraken (land-dwelling kaiju with a singular arm but dozens of hungering mouths).

Due to THE INCIDENT at the local wizard academy, the city has been flooded with frogs that turn anyone they touch into frogs. It's the party's job to clear out the frogs and recover the citizens. Good luck figuring out which is which!

This dungeon has no snares, traps, blades, pits or poison fog, nothing of the sort.

The realm has instituted mandatory standardized education and since wizardry is a basic skill like reading, writing and arithmetic everyone graduates primary education with a level in wizard and secondary education with several wizard levels.

A Sun-hat

Don't tell the players the rules.

have a game where if a pc dies whatever killed them replaces them as a party member even a trap or a fall

Oh no! All RPGs are delayed because the ontologically evil minions that it's morally uncontroversial to kill have unionised and gone on strike.
