But that doesn't solve the problem of unique magic items, such as the Stag's Helm in the Pathfinder setting. It's an item that the Stag Lord has about him. But it's a relatively simple magic item so here's my take of it:
Description:
This striking helmet is crafted to resemble the skull of a mighty stag. Although made from bone, the antlers and helm are as strong as metal. When worn, the helm greatly enhances eyesight and hearing, granting a +2 bonus on Perception checks. In addition, once per day the helm may be called upon to enhance any ranged attack made by the wearer to make an insightful shot. Activating this ability is a free action, and once activated, your next ranged attack against a target within 30 feet is made with advantage. If you don't make a ranged attack within 1 round of activating this power, the insight fades and is wasted for that day.A worshiper of Erastil who wears this helm may utilize the insightful shot ability up to 3 times per day.
The Perception check isn't a big deal as both games have Perception skill checks. The original item had a feat and I didn't want to break down the feat and go into all that detail when there was already a mechanic to represent gaining some advantage, in this case, having advantage on an attack roll.
The image is from the Kingmaker Game Master Item Cards. They're inexpensive clocking in at under $10 and can give you some visual cues to various things that don't necessarily just copy the art from the RPG products. The cards are a nice idea but it's rare that the bottom of the deck's stay together and even rarer when I can open the set without inflicting some damage to the box itself. Argh!
Anyone else rolling up new magic items or are people still waiting on the official book?
