???'s Only Friend

Complete the Boss Rush as ??????'s Only Friend

???'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 TechniqueInstead of firing tears, Isaac controls one floating tear that hover over obstacles. This tear deals constant damage when held in place over an enemy. and Robo-Baby 2.0Fires lasers at any enemy in its line of sight and moves based on the direction Isaac is firing tears..

Notes

• Unlike The Ludovico TechniqueInstead of firing tears, Isaac controls one floating tear that hover over obstacles. This tear deals constant damage when held in place over an enemy., you can't control it with your mouse if you enabled the mouse control in the config files.
• 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.
