How It Works in Charm of Undying

When the totem is in your charm slot, it behaves just like a held Totem of Undying - it just fires from the accessory slot instead of your hand.

• Automatic trigger. The instant you take damage that would reduce you to zero health, the equipped totem activates on its own.
• Instant revive. You are pulled back from death, your health is restored to a small amount, and you gain Regeneration, Fire Resistance, and Absorption, exactly like a normal totem save.
• On-screen animation. The familiar golden totem pop-up and particle burst play so you can clearly see that a life was spent.
• One totem per save. Each revive consumes one Totem of Undying from the charm slot. Keep a spare if you want repeated protection.
• Hands stay free. Because the totem lives in the charm slot, you keep your weapon and shield (or any other items) equipped through the whole fight.

This makes the totem reliable in situations where you might not have time to swap it into your hand - falling into lava, ambushes, the Nether, deep caves, or a sudden burst of damage.
