Heavy armor is a form of armor that requires the armor proficiency (heavy) feat to equip and use effectively, and is worn in the Armor slot. It provides a lot of protection from physical attacks by effectively encasing the character in a solid shell. Unfortunately this hinders a lot of movement so is not very popular among characters who rely on dexterity or those vulnerable to arcane spell failure.
This type of armor includes: Banded mail, Splint mail, Half-plate, and Full plate.
