I like to use “first” Items in my Campaigns. They are the first ever created version of something so everything else is merely a Shadow of their power. They are really rare and of course only one of each exist. Most of them are Powerful but also to Powerful to control for a long time.
the first Dagger (hand, finesse, ignores Armor, +1D10 Damage if used to backstab)
This Dagger is merely a sharp Flint with Leather wrapped around it. It absorbs any Blood that comes into contact with it.
Any Time you spill Blood with it Roll (no Mod)
10+ = You get +1 ongoing on Rolling the Spill Blood Roll until you Rest.
7-9 = You get a Bloodlust and have to attack again as soon as possible
6- = You have to kill the most powerful Person you see
i have some more of them if you like but first this one 😉
