You sense a matrix formed using Elemental mana, commonly referred to as the Targeted Magic Focus enchantment.
The enchantment is incredibly precise. You sense it was enchanted using a red heavy fount with a rough surface making it minor grade with enhanced magnitude. You perceive rather thick and perfectly clear lines empowering the enchantment. This enchantment was tuned to provide additional magnitude and a moderate damage and accuracy increase to targeted spells.
