Bit of back story, we are on a quest to stop an evil Egyptian got from returning to the mortal realm, on dnd5e. We have just snuck through a cave into the evil city, and need a distraction. These are our heros: half orc druid Thurr, high elf Palladian couple Hafsa and Cyro, half drow wizard Marty’s, and an 8 foot tall dragonborn fighter/pali Elaina. We are playing on roll20 and discord.
Thurr: I cast charm person on the fire over there.
Dm: he makes the save and looks around confused.
Thurr: I cast it again.
Dm, with a slight sigh: you have bombarded him with so many signals that the second time is the charm. You begin him over and he comes along with a smile.
Thurr, ic: you know but boss man in the tent over there? We want to play a prank on him will you go start a fire somewhere to cause a distraction so we can get in?
Dm: roll persuasion.
Thurr, with a -1 charisma: oh boy, 18.
Dm, with a slightly more audible sigh: he looks confused at first, then his face lights up. Not even the dragonborn gets this excited to start a fire. You have just created a pyromaniac.
Chaos ensues and we sneak into the big boss’s base.
Elaine, ic: can you root him to the spot, Thurr?
Thurr, ic: no, I didn’t prepare that spe- wait, I got one better.
Thurr: I cast hold person.
Dm, sighing: he rolled a 1. You got him.
Elaina: I swing my blade twice (I have multi attack) and use action surge, and swing twice more.
Thurr: now, because you are attacking him within 5 feet, you have advantage, and all hits count as a crit.

Elaina: What?
Dm: What?
Rest of the party: What?
Thurr: yeah.
Dm: why must you break my things?
Elaina: I haven’t even rolled damage yet.
-12 d6 later-
Elaina: 130 damage?
Rest of the party: DAMN
Dm, in defeat: he is dead.
And that’s the story about how we created a pyromaniac and turned a bad guy into gore in 6 seconds.
