Concept: “Outraged by your impending doom, you have sworn to hunt and kill goblins wherever they may be found.”
Content: A class that accumulates goblin-related features and physical attributes; also includes a personal countdown mechanic for conversion or reversion
Writing: Fairly straightforward with a grimly witty edge
Art/design: Relatively conservative with a retro/OSR feel; some subtle work in the illustration visually reinforces the concept
Usability: May become more powerful than the average character if they survive the multiple factors working against them
