Shields are off-hand devices used to protect the user from harm in combat. Due to the way the game's mechanics are structured, shields are categorized together with weapons in inventory. They increase the wielder's Deflection against ranged and melee attacks, but slow down his attack rate. Heavier more cumbersome shields offer greater Deflection bonuses at the cost of Accuracy penalties. Small shields have no Accuracy penalty.[1][2]
In Pillars of Eternity II: Deadfire, all shields have the enchantment Shield Engagement which allows then to Engage one more enemy than usual.
