Stalker's Helm (Patreon)

Wondrous item, rare (requires attunement)

A metallic visor made to compliment the otherworldly visage of an expert hunter from the stars. Now retrofitted for use by terrestrial humanoids, its many eyes lock onto the wearer's target with eerie precision. This helm has 4 charges and regains all expended charges when you finish a long rest.

Hunting Sight. While wearing this helm as an action you can spend a charge and mark a creature you can see within 180 feet of you. For 10 minutes you are always aware of that creature's location even if it is invisible or behind solid objects so long as it is on the same plane of existence as you. For the duration, ranged attacks you make against the target ignore half and three-quarters cover. While your marked target is within 180 feet of you, you can use an action to spend a charge to learn all of its damage vulnerabilities, damage resistances, damage immunities, and condition immunities.

Copycat. You can accurately mimic sounds and voices you have heard while wearing this helm. A creature that hears the sounds you make can tell they are imitations only with a Wisdom (Insight) check equal to 8 + your Deception bonus + your Proficiency bonus.

Eerily crafted, expertly designed. Heralding from the greatest hunters in existence, this uncanny helm is loaded with technology far beyond that of our world. Able to discern a target's weaknesses and pinpoint them from afar, it has been polished and refined by elven make and design. For those who wish to hunt and stalk their quarry this helm provides all the help they could require.
