Runic Shielding (Thaumcraft 4)

Runic Shielding is a concept added by Thaumcraft 4. It provides shield points against most sources of traumatic damage (e.g., mob attacks, falling) before full damage is inflicted on the player and their armor. It will not protect against damage from starvation or drowning. The runic shield will recharge over time by using and  vis from carried wands.
