In Demon, you play as a Summoner who has donned one of several relics capable of binding and summoning demons. But in return, each relic compels its bearer to enter a mysterious tower from which no Summoners seem to return...

Starting with only a few meager powers and a weak demon ally bound to your relic, you must climb the tower, recruiting stronger demons and learning new skills in order to survive.

Though each relic is powerful, they still have limits: They only allow you to command - not directly control - the demons you encounter, and the powers you can acquire from these allies will never eclipse those of the mightiest demons within the tower. Without powerful, well-chosen allies and clever use of the abilities learned from them, there will be no chance of survival...

5/26/2017 Update Highlights

  • Faster paced combat: Increased damage and healing across the board, increased movement speed,  and increased success rate and effectiveness for status effects.
  • Relic Preservation: Relics (player and non-player alike) can now intervene to save the life of their summoner, temporarily draining MaxHP to prevent fatal damage.

Hey, small question, how are you generating seeds for each map/playthrough?
if its name and ability based then attempts can be shared right?

Also recorded attempt number 2, https://www.youtube.com/watch?v=IgOOq_ypaxs&t=25s

Demon doesn't have a seed sharing setup at the moment, unfortunately. :(

I saw the video this morning, but didn't have time to watch before work. I will check it out tonight when I get home though. :D Thank you again for posting these. :)

Just uploading and sorting life out though, will be recording a few attempts over a few months :3

Will/Have you considered making starting relics/ablilities unlockable rather then everything available in the beginning?

Oh, awesome. :D I always love seeing LPs of Demon! If they're on YouTube, I can link them on the devblog too. But, the video you linked is currently private :P

Re: Unlockable relics, I've thought about it a little! If I did do unlockables with the starter relics, I'd probably handle it like the Demonic Compendium: you'd have the option of just playing with everything, whether you had them unlocked or not, or you could run it with just what you'd unlocked. :) I'm usually in the "I want all the gameplay options now" camp myself, but I know there are definitely folks who like unlock-based systems too, because it makes things simpler for them while they're still learning by reducing the options that need to be considered, because it gives other goals to shoot for during gameplay, or both.

Ok attempt is now public and sorted, youtube was being funny about the video. Are there more demons or just those in available at the start plus trait ones? Also redcaps are so hateful and never seem worth recuiting.

Cool! :D I'll check it out when I get home tonight!

In the current version, there are over 110 different recruitable demons (this does not include variants due to random traits that can modify them.) Red Caps are a bit tough to convince to join you, but their free action self Accuracy buff and early ranged attack (even if it is only throwing rocks) are kinda handy.

Annnndd as is becoming distressingly more common, uploaded a 1/7/2017 build which fixes a moderate-sized bug that prevented enemy demons from spending stat points gained from leveling. :P Apologies for the error, and enjoy!

1/6/2017 build has been released! Enjoy! :D

Uploaded a 12/12/2016 build that fixes a few bugs. :) Apologies for the errors, and good luck in the Tower. :D

12/11/2016 build is live! Enjoy, and good luck!

Happy UI upgrades are happy. :) Enjoy the 10/13/2016 build everyone. :D

9/18/2016 build for ARRP 2016 is released! Enjoy, and good luck in the Tower!

Great to see Demon itch! Congrats, Ferret!

Thanks. :D
