Combat Action: Total Defense
As an Instant action, the combatant focuses on nothing other than avoiding knives, arrows, hurled crystalline spears, or other perils in the vicinity. Using Total Defense costs the user their Main Action for the round, and cannot be used if they’ve already employed their Main Action. They become immune to Shock damage for the round, including from Swarm Attacks, and gain a +2 bonus to their Armor Class until their next turn.
