Armor of Self Destruct

You have resistance to fire damage, a +2 bonus to AC and any critical hit against you becomes a normal hit while you are wearing this armor.

Additionally this armor can store up to 100 charges. When it is fully charged you can release it's cumulated power and cast fireball spell (save DC 15) as a 3rd level spell, targeting yourself, as a bonus action. When you do so, number of charges is reduced to 0. When you take fire damage, this armor gains number of charges equal to the damage taken.

(This black and silver plate armor emanates with fiendish energy. It's pieces of metal spread in different directions creating twisted spikes. This armor once possessed by fiendish lord, now gently lies on your chest. Great warm radiates from the huge ruby located in the middle of the main plate, only waiting to be released. The warmer you are the more you want to touch this stone.)

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.
