A custom move I am tinkering with.
A bit of background, in my campaign, most demons need to keep open a portal to the lower realms to sustain themselves, and when they are killed, sometimes the portals collapse into gemstones. I wanted to make a move for using these to draw on otherworldly power, how does this seem?
When you release the power of an astral ruby, say what you intend to do, and roll +Cha, on a 10+, choose 1, on a 7-9, choose 2
* You owe the demon realm’s master a debt.
* You take 1d8 damage, ignores armour, from the magical backlash
* You unleash a non-hostile demon, who will do what he pleases
On a miss, the demonic power does whatever it damn well pleases.
I like it so far, but kinda want a mechanic for me to say “Theres not enough power in that gem to do that, you’ll get a limited effect”. any suggestions?
