Runner

Runners are some of the most dangerous enemies in the early biomes. They can teleport to the player and attack quickly, so running from them is usually not an option.

Behavior
Their attacks are fast, and with the ability to phase through walls, platforms, and the ground, it can make them a challenge to run from. With no defensive maneuvers, it simply phases quickly behind the player, following them until it can attack. 1 second pauses are all it needs to lock into its attack animation, which is to slash the player with one of its sword arms. They can not see you through walls, or if you are on a platform directly beneath them, but can see you across gaps and will phase to you and attack if you use a bomb or turret on them within a certain distance.

Elites can teleport and attack much faster than normal, but do not gain new attacks. Most usually, elites of this enemy drop an amulet rather than weapons.

Strategy

 * Its attack can be rolled through and, while it pauses before making an attack, it is extremely vulnerable from behind.
 * Range can be used to initiate combat but isn't a very viable strategy when the runner is aggro'd because they will teleport to your location quickly.
 * Lure into a trap to demobilize and stop them from teleporting. When rooted is still able to attack.

Trivia

 * This enemy was previously named Phazer, which was, most likely, the inspiration and namesake for the Phaser skill.
 * Before its current look the runner was a recolored Zombie that would swipe at you with its claw.
