Lodestone Armor

This plate armor is lined with magnetic lodestone harvested from the plane of elemental earth. While wearing this armor, you can use a bonus action to enhance its magnetic polarity. When you do so, loose stone, soil, and minerals are immediately pulled to the surface of the armor, granting you a +1 bonus to AC but reducing your speed by 5 feet. You can use a bonus action to activate this property each round cumulatively, up to a maximum of +5 AC and a 25-foot reduction in speed. If 1 minute passes without using a bonus action to activate this property, all magnetized material falls off the armor, ending both AC bonuses and speed reduction.

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.

The wearer has disadvantage on Stealth (Dexterity) checks.

If the wearer has a Strength score lower than 15, their speed is reduced by 10 feet.
