Ring of Eternal Funding

 is a ring in.

Trivia

 * If you sided with Nedyn in The Theorems of Pandgram, but kill her afterwards, it is possible to loot a second ring from her body.
 * This item will only earn you a finite (and very small) amount of coppers in total, as stronghold turns are based on quest and experience progression.
 * The ring, including its description and the enchantment of Eternal Funding, is likely an inside joke alluding to the game having been crowdfunded. The fact that you only earn a few coppers per turn, and that you still need to complete quests and earn experience in order to progress the Stronghold turns further, alludes to the mentality and crowdfunded nature of the project.
