Runic Shielding (Thaumcraft 6)

Runic Shielding is a mechanic added by Thaumcraft 6. It is an infusion feature that allows the player to add a shielding effect to armor and baubles. This is applied through using an infusion matrix with Salis Mundus, one Amber for each level of shielding being applied, and a base unmodified essentia cost of 2(10+n) Praemunio, 10+n Potentia, and 10+n Vitreus, where n is equal to

$$10\times(2^{\text{level of infusion}-1})$$

Each point of Runic Shielding grants beyond the player's base HP and is able to absorb damage until it is depleted entirely. This shield will regenerate after a short period of not taking damage from sources such as mobs, blocks (like cacti), falling, or burning, but damage from poisoning, drowning and starvation will not reset this shield regeneration timer. The Thaumonomicon displays up to three levels of shielding one can achieve, but levels beyond what is displayed are possible, albeit at increasing cost in both Amber and Essentia and at increasing levels of instability.
