To begin with I have to admit that I really looove the table on the pages 142-143 of the 5E-DMG!
Yep, that is definitely one of my favorite parts of the DMG. When I first got it, I was fiddling around with the tables
and had my wife just give me some random numbers and applied the results to a simple +1 longsword.
Created By: a Fiend
The item is made of black iron or horn inscribed with runes, and any cloth or leather components are crafted from the hide of fiends. It is warm to the touch and features leering faces or vile runes engraved on its surface. Celestials find it repulsive.
History: Prophecy
The item features in a prophecy: its bearer is destined to play a key role in future events. Someone else who wants to play that role might try to steal the item, or someone who wants to prevent the prophecy from being fulfilled might try to kill the items' bearer.
Minor Property: Key
The item is used to unlock a container, chamber, vault, or other entryway.
Quirk: Possessive
The item demands attunement when first wielded or worn, and it doesn't allow its bearer to attune to other items.
So with just a couple of rolls I now have a sword, crafted by a fiend, that a prophesy says that it will most likely be the key to opening a portal to some hellish realm, most likely allowing the Fiends armies to come through and destroy the land.
The adventure practically just writes itself. And this was just for a simple +1 sword.
That being said, a dwarven cleric in my game got a +1 shield and giving most of the "non-wondrous items magic items" of my campaign some special features, I have the following thought concerning this very +1 shield: Are these features a bit over the top?
Minor Property: Shadowbane. The bearer of this shield has necrotic damage resistance, while protecting oneself with it (shield bonus adding to AC).
Quirk: Truthspeaker. The bearer of this shield cannot lie (as if under the effect of the spell Zone of Truth), while protecting oneself with it (shield bonus adding to AC).
Any critique, help or comment appreciated! Thanks, Mhyr.
I think those features are just fine. Nothing too crazy about them.
