Metronome is an unlockable activated item added in Afterbirth †.
Grants a random item's effect for the current room.
Beware using this as
The Lost, as it can trigger self-harm items and kill him. Using this item multiple times in the same room will replace the previous item with a new one.
Metronome cannot grant the effects of itself, or Glowing Hour Glass . Plan C
/ Blanket Holy Card / / Holy Mantle : if Metronome is used while the shield is active, any stat changes or familiars/orbitals generated from Metronome will persist between rooms until Metronome is used again or replaced with another active item. Items that modify your stats and have other additional effects will keep the stats but the effect will be gone after leaving the room. For example, the tears down applied from Wooden Cross will persist between rooms, but Isaac will not shoot three tears at once.

, Continuum , Epic Fetus , Eve's Mascara , Godhead , Ipecac , Jacob's Ladder , The Ludovico Technique , A Lump of Coal , Monstro's Lung , My Reflection , Ouija Board , Pop! , Rubber Cement , Sacred Heart , Spoon Bender , Strange Attractor Technology Zero Some items behave unusually after leaving the room while the Holy Mantle shield was active:
Items that grant flight: Isaac's appearance is reset back to normal, but he is still able to fly.
: the mushroom familiar continues to follow Isaac, but doesn't grant an extra life. 1up!
: the tear appearance is reset back to normal, but the tears still travel through enemies. Cupid's Arrow
: the tear appearance is reset back to normal, but tears can still explode when they hit an enemy. Fire Mind
: the tear appearance is reset back to normal, but tears will still leave green creep on the ground. Mysterious Liquid : does not persist between rooms. Spear of Destiny : Metronome is activated twice at once as expected, but the item chosen for the first activation is shown raised above Isaac's head, instead of the second one that actually remains active.
