The series "Deathtrap Dungeon World" by Sersa Victory over at Critical Hits, about creating memorable and deadly encounters in Dungeon World.
- Part 1: GM Principles
- Part 2: Dangers and Hard Moves
- Part 3: Death and Rewards
- Part 4: Moves from the Tomb
Sersa talks about his introduction to RPGs and his love of deadly dungeon delves at Kobold Press in Kills, Items, and Secrets: Why I’m Forever Hooked on Deathtrap Dungeons.
Sersa's site is offline for the foreseeable future, but you can find a collection of "Fourthcore" deadly delves for D&D 4th edition and Dungeon World in my Google Drive.
