Never let them GM. Ever. Because they’ll totally wipe your sorry character’s ass, that’s why.
Case in point: today I crack open the D&D Starter Kit with my boys, and my youngest says that he wants to “play the bad guys”. Ok, says I, and hand over the dungeon tiles which he lays out with a large central room and several exits including one that leads to a long row of bookcases. He says that we need to get to the end bookshelf as that’s where a key is hidden that opens the other doors. Fair enough.
Except we didn’t even make it out of the first room.
He’d dropped a couple of Wolves in there to start with, which we despatch without much difficulty, then I (playing a Dragonborn Paladin) headed to a temptingly-positioned chest in a corner. Silly me.
Inside the chest, he said, nestled a Rat Swarm, and hiding behind it was a Stormclaw Scorpion. I’d gone through the bestiary in the Starter Kit with him already (incidentally, it’s an excellent low-level Monster Manual. Seriously) and he’s spotted synergies between the Rat Swarm and the Stormclaw Scorpion. Y’see, the Rats have an Aura that gives it a free basic attack against any creature that’s within one square of the Swarm, and the Scorpion has a Sting attack that Immobilizes foes. And they both have attacks that deal ongoing damage. The net result is within one round my poor Paladin is stuck in place, taking 8 hp damage per round and being torn apart by Rat’s teeth and Scorpion claws.
I didn’t stand a chance.
Meantime, my eldest (playing the Eladrin Wizard) is standing back laughing. Until they go and do exactly the same thing to him.
7 years old. His first TPK.
I’m so proud.
