Magic Items

Plate consists of shaped, interlocking metal plates to cover the entire body. A suit of plate includes gauntlets, heavy leather boots, a visored helmet, and thick layers of padding underneath the armor. Buckles and straps distribute the weight over the body.
Strange material: This plate armour is made of magically enchanted stone slabs, and there is no metal used enabling druids to wear it.

Ticket to Ride. You’ve successfully completed the
task that Shirvasa the sommelier has set for you,
and in exchange he provides you with a voucher for
travel by gondola within the Abriymoch city limits.
Present it to any gondolier and not only do you ride
for free, but the devilish gondoliers treat you as one
of Shirvasa’s associates - only with more respect

This hell-forged battle standard is made of infernal iron and fitted with a small, unopenable cage containing a quasit. The trapped quasit is incapacitated, and its cage has AC 19, 10 hit points, and immunity to all types of damage except force damage. If killed or somehow released, the quasit disappears in a cloud of smoke, and a new one appears in the cage, provided the cage is intact.
While you hold the banner, your weapon attacks and those of all allied creatures within 300 feet of you count as magical for the purposes of overcoming damage immunities and resistances.

The storm giant quintessent Dessa imbued this belt with her elemental strength. When the belt’s fantastic strength is used lightning dances around the wearer while a warm desert wind blows in the area. While wearing this belt, your Strength score changes to a score granted by the belt (29). If your Strength is already equal to or greater than the belt's score, the item has no effect on you.

This armor never gets dirty.
