Armor of Karathas

"The knight Karathas was well known across history as the champion of the first king. All manner of foes and unholy creatures that threatened peace, was to be slain quickly by the knight. Karathas served a king whom wielded a blade that the winds feared, flesh feared, and no word was found as a lie in its presence. The king commanded his finest blacksmith to forge a full plate of armor to bestow upon his champion. Nimble, and strikingly strong, thanks to the richest, purest form of virgin iron plucked from the crust of the world, in the early dawning on Kythorn 20, 1241AC, The Summer Solstice; aided Karathas to fell many terrors and evils, from dragons and demons to ghosts and giants. He died on Uktar 14, 1301AC, from a beholder nestled away in the underdark." - War Stories After The Calamity, Vol.3

This dark gray, red-trimmed plate armor consists of a chest piece, pauldrons, and grieves. Between the pieces is a light yet durable leather, tanned in a deep brown, fastening the set together. A symbol inlaid with gold, in the shape of a human hand is seen on the front and center of the breastplate. 

This suit of +3 armor provides superior comfort as well as extreme protection. You have advantage on Saving Throws against the Frightful Presence and breath Weapons of Dragons, no disadvantage to stealth, and the full Dexterity-AC modifier, rather than the cap of 2. It also grants immunity of critical hits while wearing this armor.

The spirit of Karathas: Any Fiends, Dragons, Giants and Aberrations in a 60ft radius of the wearer must roll a DC 15 Constitution saving throw. Anything that fails has its hitpoint maximum reduced to half for 24 hours. This ability can only be used once per long rest.

This armor consists of a fitted metal chest piece worn with supple leather. Although it leaves the legs and arms relatively unprotected, this armor provides good protection for the wearer's vital organs while leaving the wearer relatively unencumbered.

Notes: Immunity: Critical Hits, Advantage: Saving Throws, Bonus: Armor Class, Long Rest
