Ok, I like the dull and lifeless form of the non-wielded knife. I like that quite a bit, actually. As though the knife has the latent ability, but requires the lifeforce of a certain human to activate it. It would also be good for smuggling it by those who could detect magic. I may even use that thought, someday.
Apart from that, I don't really like it at all.
Edged weapons which can cut through anything are overdone and overpowerful.
Daggers to cut through dimensions are also done a bit, though not quite as often.
Where did the dagger come from? Why is it magical? How does the knife-bearer lose his finger and thumb when he becomes it?
Anywho. I'd give this a 2.5, but I don't think its quite worth a 3, so I voted a 2/5. Go to Comment
If the author had given credit to Pullman for taking the idea from his (amazing) book, it would have been fine. However, no credit was given and the item is practically a carbon copy of the book's knife, right down to the missing thumb. And the book's description is even better. I don't especially like to beat down a dead goose, but this one particulary irked me. Go to Comment
On a location with numerous webs, and at least one big spider, there is a something inside a cocoon. It is humanoid in shape, still moving. If the heroes free it (not before they kill or drive away the spiders), they meet a ... zombie!
The poor zombie wandered the dungeon alone, and tried to kill a big living creature (= a spider). The spider used the usual treatment, even if this victim did not look tasty. The zombie can be easily killed as any other zombie. It got but several doses of spider-poison, so can be something worth if it is extracted. You can mention to a druid or ranger the fact the spider had no poison anymore.
