Skulls 3 (normal) 7 (elite) Theme Primal One Introduced Version 31.0 Description • Vortex moves like lightning and speeds other Bloons along! • When each health bar skull is reached, Vortex shields itself and sends out a shockwave that stuns nearby Towers before retreating up the track. • Vortex emits a regular storm pulse, destroying projectiles, including any non-Powers on the track.

Vortex, titled Deadly Master of Air, is a Boss Bloon in Bloons TD 6, introduced in version 31.0. It is the third boss introduced to the game.

Vortex is one of the fastest bosses, but every time it reaches a skull on its health bar it is knocked backwards on the track. Additionally at the skulls, Vortex temporarily shields itself from most projectiles and stuns nearby Towers including Paragons. Vortex is capable of regularly destroying nearby projectiles. While Vortex is present on the map, all Bloons spawn with a speed boost until they touch Vortex.

Most Boss Bloon Events featuring Vortex have challenge rules that increase Bloon Speed and MOAB Speed.

Mechanics

Storm pulse

Vortex emits a storm pulse every 5 seconds, destroying nearby projectiles in a 80 unit radius including spikes placed by Spike Factories and collectibles from Banana Farm and Bloon Trap. Powers such as Camo Trap are unaffected.

Slipstream

While Vortex is alive on the map, all Bloons have a 2.5× speed boost that goes away upon reaching Vortex. On multi-lane maps, Bloons on a different path than Vortex may keep the speed boost all the way to the exit if their path does not reach Vortex.

Skulls

Upon reaching a skull, Vortex stuns nearby towers, generates a temporary shield, and is knocked 100 units back on its track. A single attack cannot damage past a skull; for example if an attack normally deals 4,500 damage and Vortex has only 1,000 health remaining to the next skull, that attack deals only 1,000 damage.

Shield

This section is incomplete. You can help out by expanding it. The editor who added this notice elaborates: Incomplete list of attacks that damage through shield

When a skull is reached, Vortex is protected by a shield for 6 seconds which causes most projectiles to deflect away from Vortex, not harming it. Some attacks can penetrate the shield, including:

• Any attacks that deal damage to the target directly without using a projectile, such as Sniper Monkey shots and Captain Churchill's Machine Gun
• Mortar Monkey shells
• Ballistic Missile's missiles
• The First Strike Capability and Final Strike abilities
• Plasma Accelerator and Ray of Doom's beams (not Plasma Accelerator's focus point)
• Tech Terror and The Anti-Bloon's abilities
• Heart of Thunder lightning

Shockwave

When a skull is reached, all towers nearby Vortex become stunned. While stunned, towers cannot attack, use abilities, charge ability cooldowns, generate income, or be sold normally. Items may still be purchased from Geraldo's Shop even if Geraldo is stunned. When a tower is stunned, all of its sub-towers also become stunned. Heli Pilots and Monkey Aces are only stunned if their heli-pad or runway is in range, respectively. Master Builder's Paragon Sentries cannot be stunned unless Master Builder itself is stunned, which may be a bug. The stun duration and radius of the shockwave increase at higher tiers.
