Unicorn Stump

Unicorn Stump is an activated item.

Effects

 * Upon use, grants invulnerability and increased speed for five seconds but removes the ability to shoot tears while the effect is active.

Synergies

 * ???'s Only Friend: The fly can still be controlled while invincible.
 * 9 Volt: Causes the Stump to charge in 15 seconds, allowing Isaac to become invincible multiple times in a single room.
 * Car Battery: Stump is active for 12 seconds instead of 6.
 * Mom's Knife: Isaac can skewer enemies on the knife by running into them while invincible.
 * Midas' Touch / The Virus / E Coli / Aries / Orbitals: Isaac can use the stump to turn enemies into gold/poop and damage/poison them without getting hurt.
 * The Ludovico Technique: The tear stays in place while Isaac is invincible; although Isaac cannot move the tear, it will continue to damage enemies during his invincibility. This is very useful for stationary enemies.
 * Marked: Isaac's tears will still fire, but he will be unable to move the crosshair while invincible.
 * Orbital Familiars: Isaac can hurt his enemies with these familiars while being invincible.
