Drone Orb

The Drone Orb is a projectile used by various towers, primarily the Wizard of Orbs.

Drone Orbs are powerful projectiles that have gravity-like attractions towards bloons. It is attracted towards the average center of gravity of all the bloons and the farther away it is, the slower it is attracted.

Drone Orbs have infinite pierce, which, if added with the rule above, can in theory make them virtually invincible, since they do not fade between rounds. However, they will fade if they are starved, which means they haven't touched a single bloon for 10 seconds.

Drone Orbs have vastly varying effects, from the most basic being the green Drone Orb, which has the texture of a 0/0/0 Wizard Monkey's bolt and does 1 damage upon collision, to ultra-powerful Drone Orbs that take away hundreds or even thousands of damage per second and spontaneously emit darts, bombs, tornadoes, sun god projectiles... you name it!

A single Drone Orb is worth $10,000 and it spawns as a green orb, the most basic. However, this cannot multiply or upgrade, so it might be a better investment to buy towers that emit these Drone Orbs.
