Where to get it: On the final level, when you defeat the final boss, and you do so with ALL other artifacts active, you will unlock another boss, which is an upgraded version of the final boss, sporting double health, double damage, a new laser beam ability that he frequently uses, and no access to the extra endboss features (medbay etc). Once you defeat him, you unlock this artifact. What it does: All enemies move at half their speed. Projectiles from both you and all enemies move at half their speed. You fall at half speed. All boss health is increased by 100% and teleporters now require you to survive 180 seconds.
