???'s Only Friend is an unlockable passive item.
Effects
- Gives Isaac a controllable follower that damages enemies on touch, dealing 2.5 damage per tick. Works similar to The Ludovico Technique and Robo-Baby 2.0.
- Template:Transf
Notes
- Unlike The Ludovico Technique, it cannot be controlled with the mouse, even with mouse control enabled.
- Holding two opposite fire keys (both left and right or both up and down) at the same time will keep the familiar in place, while making Isaac fire in the direction of whichever fire key was pressed second.
- This can help during combats with bosses who do not move a lot, as the familiar can continuously damage the boss when kept stationary.
- On some keyboards, holding opposite fire keys may cause other keys to become unresponsive.
