Doomed Dungeon is a LitRPG Web Serial Novel available here.
Bastill, a Journeyman Sculptor, drinks a doctored drink at the local pub, and wakes up as a Dark Sorcerer's soon-to-be victim. Turns out she needs a Dungeon Core as an ingredient for a ritual - and she decided to simply make her own... using Bastill's soul.
The newly-made Dungeon Core learns the Sorceress will return in five years to harvest him —once the Core has matured a bit— meaning that if Bastill wishes to survive that meeting, he has some levelling to do...
Doomed Dungeon contains examples of the following tropes:
- A Dungeon Is You: The protagonist.
- RPG Mechanics 'Verse: Everyone has a status and skills.
- Soul Jar: Essentially what the necromancer did.
