Armour of Vines

You gain a +1 bonus to AC while wearing this magical half-plate. Additionally, in response to taking damage while wearing the armour, you can use your reaction to make magical vines grow from the armour and cling to you, causing you to gain 15 temporary hit points, which take as much of the triggering damage as possible. While the vines cling to you, you are grappled. At the end of your next turn, the vines wither wither away, and any remaining temporary hit points are lost.

Half plate consists of shaped metal plates that cover most of the wearer's body. It does not include leg protection beyond simple greaves that are attached with leather straps.
