Hot on the tails of unlocking the two ribbon bookmarks in the Demonic Grimoire, we're back again with news on the next achievement that's been smashed through...
Holographic Sticker!
All backers at physical pledge levels (i.e. including a physical copy of the Demonic Grimoire) will receive a free holographic sticker featuring an art piece from the book. There are so many awesome illustrations in the book, we couldn't decide which to sticker-ize. So we thought we'd let you decide in a poll!
Vote for your favourite sticker here! The poll will be closing on May 27th, so get your vote in by then. To aid your decision making, here are larger images of the sticker design options.

In addition to achievements being unlocked on the Demonic Grimoire and other campaigns in OSE Month, we also have plans for achievements based on the success of OSE Month overall:
Discord AMA: The first community achievement is the Discord Ask Me Anything session, mentioned in the previous update. That'll be unlocked once all OSE Month projects fund. 13 / 17 projects are funded as of now, so we're nearly there! The AMA will be a great chance to jump in and chat directly with the creators of the Demonic Grimoire and other OSE Month projects.
More? Once all projects have funded, we do have further community achievements to announce. For now, let's just say that something evil sounding may be on the horizon...
We are delighted to report that your copies of the Demonic Grimoire are being rapidly enhanced by eldritch forces (also known as funding achievements)!
We've now unlocked the first two achievements: the addition of two bookmark ribbons to the Demonic Grimoire — one in hellish red and one in abyssal black! Here's a preview of what they'll look like:
Upcoming Achievements
We have more achievements coming up, awaiting sufficient numbers of pledged souls:
Holographic sticker: If our funding total reaches $200,000, all backers at physical pledge levels will receive a shing holographic sticker to adorn a tome, libram, grimoire, scroll-case, brazier, or laptop of your choice. We have 5 possible sticker designs picked out, but the final design will be selected by backers! Cast your vote here!
OSE Month AMA session on Discord: Have any questions about the Demonic Grimoire or any of the other OSE Month projects? Once all OSE Month projects have funded, we'll be gathering as many of the participating creators as possible and jumping into the Necrotic Gnome fan Discord server to answer all your questions. Currently 9 / 17 of the projects have funded, so go and check out the full lineup and lend you support to some more fantastic creators in the OSE community.
And remember: if you back the Demonic Grimoire at a physical pledge level + 6 or more other OSE Month projects, you'll receive a free foil pack of 17 monster cards, one contributed by each OSE Month project!
