Done a quick search and can't find anything, but has anyone given more effects to the Tooth of Ahazu?
One of my players (halfway through the battle at the end of ToD) is THIS close to jamming the thing in his mouth, and I'd like to have some more effects (good and bad) to simply pluses to grapple checks
Can add some myself, but wonder if someone has done it already
Here is someone's attempt to convert Ahazu's Vestige for use with the Pathfinder Occultist class from Secrets of Pact Magic. So you might be able to get some ideas from there.
Do note though that the author of SoPM, Alexander Augunas, posts a little further down saying that the conversion is a little bit broken, so take that into account.
