Ball of Tar

Appearance
A black ball.

Pick Up Quote
Sticky feet...

Effect
Makes Isaac gishy black, and gives him yellow eyes.

When picked up, Isaac starts leaving creep behind him, which disappears after a certain amount of time. Any enemy that walks in the creep is slowed down. Also gives Isaac a 1/10 chance to shoot a slowing tear every time he shoots.

Interactions
This item can be really good with Technology because of Technology's infinite range and high rate of fire. That gives a bigger chance of shooting slowing (and laser) tears.
