Appearance

Ghost Droid 2.0, its second variant is red and slightly transparent but its torso and helmet are both solid red.

3.0

Ghost Droid 3.0, its third variant is dark blue and slightly transparent but its torso and helmet are both solid dark blue.

Behavior
When it is aggroed by a player, either by entering its aggro range or using a ranged weapon and getting it to half ♥️HP, it will turn invisible, only turning visible again when attacked during that state.

Each variant increases its ♥️HP by 150, ⚔️Damage by 2 and🏃‍♂️Speed by 1.

Combat Tips
Ghost Droids have moderate health but can potentially deal a lot of damage unexpectedly. You should never let the Ghost Droid catch you off-guard.

If you can estimate the speed of the Ghost Droid well, it will allow you to attack it when it is close but not yet touching you.

If the Ghost Droid spawns along with other droids, you can use the other droids as a gauge to estimate where the Ghost Droid is.

Look out for the tiny particles that the Ghost Droid emits if you've lost track of it. High graphic settings increases the amount of these projectiles.

When it is chasing you, the Ghost Droid can be revealed early by hitting it with a projectile. Crossbows are better for this as they fire arrows in a straight line, while slingshots fire in a parabolic trajectory.

Trivia

 * For a brief moment after the Ghost Droid first spawns, if a player is in its aggro range the Ghost Droid will pursue the player without turning invisible.
 * If the Ghost Droid is hit with a ranged weapon by a player it cannot pathfind to, it will not react to being hit.
 * Kiting Ghost Droids while very quickly tapping A and D will slow you down, allowing you to reveal the Ghost Droid easier.
 * If a Ghost Droid gets the Leaking, Flickering or Protected modifiers, it will show where the Ghost is, while still invisible, making it a practical joke to fight.
 * Ghost Droid 3.0s are really tricky to fight against as they have 16 (alongside dealing painful damage), so don’t try the kiting-zigzag strategy unless you really know what you’re doing.
