Erratic

Rocket Storm shooting rockets at erratic angles, the rockets randomly moving in a serpentine motion with further erratic behavior

Erratic is a projectile behavior characterized as having random projectile deviation or deviations of movement that cannot be adequately controlled by the player. It is part of the damage types family.

Erratic is represented on Bloons Wiki as , the upgrade icon for Rocket Storm in Bloons TD 6, characterized by the randomized serpent-like behavior that the ability rockets produce. Erratic is distinguished from RNG in that its RNG factor can be amended by proper positioning or upgrades that reduce inaccuracy (e.g. Rocket Storm with Focused Firing or Spike Factory's Smart Spikes upgrade that completely takes the RNG factor out of the Spike Factory). For attacks that are produced as a Spawn , which are produced "in the middle of nowhere" and are just created, if it keeps moving places outside of player control then it can be considered Erratic if its positionings aren't only affected by a Path-Based Mobility (e.g. Exploding Pineapple Aces can drop pineapples in consistent spots based on flight patterns if flight path micro is optimalized, but pre-25.0 WoF still uncontrollably deviates even if there is a tiny amount of track in its range due to no innate tower mobility).

Typical examples with Erratic include Spike Factory, Dartling Gunner, Mortar Monkey, and Obyn Greenfoot's Brambles ability (although he adjusts the positioning of them if bloons are within range). Shotgun Spray features Erratic in its spray of angular attacks, and is a separate variant of Spray for that reason.

Because Erratic can be quite RNG-heavy, some elements of Erratic have been softened or entirely removed for some upgrades, the most notable example being Wall of Fire, which had a notorious history for being dependent on RNG (due to it's cheap price, but high contact damage making it valuable in completing challenges), although like all towers with the Erratic projectile behavior, proper positioning could reduce the RNG of Wall of Fire's blaze attacks. On Version 25.0, Wall of Fire upgrade was changed so that it always targeted the closest to the Wizard Monkey by default and no longer spawned in random locations. Similar happened to Cleansing Foam and Obyn Greenfoot's Wall of Trees, which now default to Close and can be re-targeted anywhere.

• Obyn Greenfoot's Brambles when no bloons are within range
• Admiral Brickell's sea mines
• Geraldo's Killer Rabbit's movements

Upgrades formerly with Erratic

Some upgrades had lost Erratic, mainly to reduce elements of potential RNG. This includes, but is not limited to:

• Wall of Fire (now defaults on Close)
• Cleansing Foam (now defaults on Close, and can use Selectable Target in BTD6 and BTDB2)
• BTD6 Obyn Greenfoot's Wall of Trees (now defaults on Close in BTD6, and can use Selectable Target)
• BTDB2 Obyn Greenfoot's Brambles and Wall of Trees (now defaults on Close in BTDB2, and can use Selectable Target)
• BTD6 Gwendolin's Cocktail of Fire when no bloons are within range (now defaults on Close, and can use Selectable Target in BTD6 and BTDB2)
