Rules
 
A mini equipped with shielding prevents the first, and only the first, instance of non-melee damage that is dealt to it each turn. 
 
Relics
 
You may pay a relics influence cost and place it into your barracks, it can be exhausted the same turn it is played. 

From your barracks you may pay a relics equip cost to attach that relic to a mini you control that's on the battlefield adding its stats and abilities to that mini. 

If a unit equipped with a relic card dies or leaves the battlefield, set shielding to the side and place a trinket on the space  where that minion was standing. If another mini you control moves onto that space, you may pay the equip cost to attach shielding to that mini.
