Armour of the Iron Oak

Armor Type: Medium or Heavy

Armor Class: Base armor class is 14 + Dexterity modifier (maximum 2). If the wearer is proficient in medium or heavy armor, they may add their proficiency bonus to the armor class as well.

Strength Requirement: The armor requires a Strength score of at least 13 to wear.

Stealth: The armor imposes disadvantage on Dexterity (Stealth) checks.

Magical Properties: The armor is imbued with magic that enhances the wearer’s abilities. The following properties can be chosen:

Barkskin: The wearer gains resistance to bludgeoning, piercing, and slashing damage from nonmagical weapons. Additionally, the wearer’s AC increases by 1.

Entangle: As an action, the wearer can cause roots and vines to sprout from the armor, attempting to grapple a creature within 30 feet. The target must succeed on a Strength saving throw (DC 8 + the wearer’s proficiency bonus + the wearer’s Strength modifier) or become restrained. The wearer can use this feature a number of times equal to their proficiency bonus, and they regain all uses after a long rest.

Ironwood: The armor is treated as if it were made of metal for the purpose of overcoming resistance and immunity to nonmagical attacks and damage.

Thorn Shield: The armor sprouts thorns that can harm attackers. When a creature hits the wearer with a melee attack, the attacker takes piercing damage equal to the wearer’s proficiency bonus.

Wild Shape: The wearer can use their action to transform into a small tree. In this form they cannot move, but may sway their branches and use the entangle spell above. They may do this once per long rest.

Material Cost: Crafting the armor requires the bark of an ancient, magically-enhanced tree that is at least 500 years old. The bark must be harvested during a ritual performed by a druid or other magic user. The cost of the bark is 500 gp.
