Aptly named due to the fact that upon the death of the person wearing this, the heart takes out everyone in the perimeter in a fiery blast

Excellent for melee, the only time it can be used. Trigger the sword and a fiery ring emanates from your unit, selectively frying just the bad guys

Shields the unit from enemy arrows. And artillery as well, methinks. However its not 100% projectile proof so keep moving.

Very useful artefact especially for some missions where the enemy has lots of archers
