88: The DM being intentionally vague with what the party discovers on their checks, regardless of how well the party rolled, just to make sure that the party has no way of avoiding a trap or an ambush that the check should have hinted at. If someone is playing a Ranger in their favored terrain, and they rolled a 27 on their Perception check thanks to the Bard's Inspiration and the Cleric casting Guidance, they should at least be able to have some indication that there is are goblin archers up on that cliff.

89. The gm spoiling the storyline

Oh and the final boss is a undead dragon, by the way watch out in that forest there are goblins with blow darts.

90: when the entire party is wiped out because there are new players and the dm decided to send them into a cave with like 50 armed drow cultists. in the first 5 turns of the game.

91: When DMs refuse to teach new players anything about the game, going so far as to not let them borrow/send copies of the PHB, and then running the hardest campaign imaginable (Yes, this was kinda inspired by Otter's but the statement stands)

*o hi*

(Hey Fry, how goes it?)

*waiting on the half-blood rp*

92. The dm getting fed up with the parties shenanigans and making a tpk.

93. The dm bringing in an op character that kills everything and the characters need to rely on him to beat the campaign

94. The Players characters being side characters while the DMs character is OP

95: All of the DMs characters being self inserts

96. DM: Okay so my character gets a vorpal long sword. +20 plate armour and an antimatter rifle.

      Players: Its a medieval campaign though…

       DM: Don’t like it you can leave, okay so all of you each get 1 copper piece.

In other words DM’s spoilt character even if it doesn’t work with the storyline. Also ties in with abusing power.

97. The dm allowing you to adopt a cute baby kobold who gets devoured by a dragon in session 3

98. The spell feeble mind or even polymorph >:)) as a cantrip by the mindflayer god Cthulu

99. Spending hours having to make new characters after the dm kills them all within 5 minutes then finally turning the tables and making their own campaign only to have the players complain about.

100. Killing immortal monkeys for a quest

101.

the monsters have counterspell.

102. Players that don’t care about what happens in the game, but only look up from their phones when it it their turn in combat or called out outside of combat.

*every single player I have had irl has done this and it sickens me.*

103. When you as the DM are trying to warp the battlefield and the players only need to get a 5 on a CHA save because the monster has a terrible CHA stat.

104. When the dm makes their character the main character and one shots every monster so the players end up just sitting there.
