1

Rocks fall; everyone dies. All players reincarnated as the (lvl 1) child of one of the NPCs the party terrorized.

2-3

A horde of Vikings (or space Vikings, as the situation warrants) storms the tavern/ castle/ empty plain (etc) and whisks the players off to become slaves/ brides. No saving throw.

4-5

All players are body-swapped with the reanimated corpse of one of the people they’ve slaughtered during the campaign. The hapless NPCs now reside in the players’ former (over-powered, “I found a source book with stats for a half-dragon demigod psion) bodies. The NPCs remember exactly what, and who, killed them.

6-7

Apocalypse now! In a magic-based setting, all magic suddenly fails. Inherently magical races find themselves turned into ordinary humans. No magic items or abilities continue to function, except for those wielded by the horde of tentacle demons heading the party’s way… In a modern/ technology-based setting, all technology suddenly and inexplicably fails. (There are still tentacle demons.)

8-9

The party encounters a wandering Rob Bricken! It uses a Fanfic! It’s super effective! If the campaign was anything other than Call of Cthulu, the fanfic acts as a gateway into a Call of Cthulu- based world. If the campaign was already CoC, a Lovecraftian horror appears, reads the fanfic, and takes notes before disappearing with a menacing grin and an ominous “Soon…”

10-11

The party encounters a “mystical field” which robs all spellcasters/ magic users of their ability to perform magic. These powers are instead granted to the party’s fighters/ non-magic users, who are stripped of all weapon and armor proficiencies. Note that skills and attributes are not in any way affected.

12-13

Deadpool appears and insists on joining the party. Hijinks ensue.

14-15

Time travel. Regardless of what debauchery the players are currently engaged in, a portal opens beneath them, depositing them in a strange far away land. If campaign was set in modern times, the PCs are now in ancient times. If the campaign was classic DnD or similar, it is now d20 modern. Also, the natives are hostile.

16-17

A local monarch (or god, if the players could safely turn a mere mortal monarch into so much royal jelly at this point) appears before the party and demands that they join him/ her/ it in a game. The opponent then produces paper and writing implements, various dice, and a red cloak (which the opponent immediately dons). The metagame has begun.

18-19

All of the players’ grandmothers suddenly materialize to give them a stern talking to. If for whatever reason, the player’s character does not HAVE a grandmother, either the reanimated corpse of their grandmother appears, or the player’s chosen deity appears to bitchslap them. All players’ skills and attributes are halved for three sessions, or until they mend their ways and chip in to buy the DM a nice fruit basket (or similar).

20

The players lucked out… this time. They should be given a vague warning from a wandering prophet (or similar) that a “judgment will come upon them if they do not mend their ways.” If the party does not improve behavior within one session, roll again.
