Hey all,
I'm GM'ing a campaign right now and when I started I gave the players the opportunity to do a bit of world building in their backstory in order to flesh it out and make it exciting. I told them to be creative, and one of them incorporated an artifact into his story. Said artifact created a portal to another plane/world upon coming into contact with the character's blood.
My question is, are there actually magic items which are 'blood-activated'? I've dug around a bit, but haven't really found anything satisfactory. It's going to be an item that I more or less have to design based on the concept, but I was hoping to find some sort of baseline to work with. Has anybody seen anything similar in function?
First things that come in mind is spell blood money and that magus racial archetype for tieflings.
Essentially you can create such item, but you have to decide how bloodfeeding works mechanically.
It can be either hp damage or physical score damage.
So how to determine? Plane shift scroll cost 1.125k. Bloodmoney says 1 STR damage for 1k. So 2 damage to strength. Based on this I would go 1d4 damage to either random (1d3) ability score or CON or STR damage and 1d6 bleed damage.
Currently I do not know of any "blood" items.
And I do think this question belongs in advice section.
