Game Description: Grants TP bonus when blocking an attack with a shield.
In order to receive TP from being hit, it requires that the unblocked hit would have done more than zero damage. If you would have taken 0 damage (due to an effect such as Stoneskin or Phalanx), no TP will be gained even if your shield blocks.
Prevents spell interruption from attacks that are blocked with the shield during spell casting. Any attacks that are not blocked by the shield still have a chance to interrupt.
It is speculated that on shield block, one would gain 1 extra TP with Shield Mastery I, 2 TP with Shield Mastery II, and 3 TP with Shield Mastery III.
Adoubeur's Pavise adds exactly 1 TP when blocking for 6 TP total. Store TP does not play a role.
