Guardian's Heart

Note that the shield is "spongy" in the sense that with any amount of one shield, taking more than 60 damage will remove the shield and not damage your health. In other words, you can't take damage to your "normal" health until the shield is completely depleted.

Item Synergies

 * This item seems to synergize well with "out of combat" items such as the Sprouting Egg and the Red Whip since taking damage while the shield is active does not make the player enter combat.
