Supa-Vac

"Supa-vac pulls nearby bloons in and holds them near the tower for 8 seconds."

- BMC Steam description

 is the final upgrade on the second path for the Bloonchipper. It gives the Bloonchipper the Supa-Vac Ability, which makes it suck up and hold every single non-MOAB-class Bloon near the Bloonchipper for 8 seconds or until it sucked up. In BTDB Mobile, the ability can also suck in MOABs and BFBs, but it only sucks in BFBs for half the normal time (4 seconds).

It costs $5100 on Easy, $6000 on Medium, $6480 on Hard, and $7200 on Impoppable. In BTDB Mobile, it currently costs $10,000.

Summary
In general gameplay, Supa-Vac is largely irrelevant as the main problems coming into later rounds are generally going to be MOAB-class bloons, and Bloonchippers aren't very efficient at handling grouped bloons. However, Supa-Vac provides a form of stalling and concentrated bloon relocation that no other tower in the BTD5 generation can provide, which is to suck an infinite number of regular bloons within range into itself. Combining Supa-Vac with high-pierce towers makes for a dynamic combo.

In Bloons TD Battles Mobile, Supa-Vac is more expensive but much more versatile, and it is mainly used for stalling masses of MOABs and BFBs.

Tips

 * Supa-Vac ability does not require a crosspath to suck in Leads or Ceramics, no matter what game Supa-Vac appears in.
 * The ability does zero damage in itself, but its infinite pierce and stalling power is valuable in a situation where there is an enormous bloon rush. When properly placed and timed, the ability can save the player from dying from a large crowd of bloons. Then the player will have more time to deploy abilities or towers to save themselves.

Typos
The text for the ability when the player scrolls over the button to use it says the ability lasts "for 10 seconds" instead of "for 8 seconds". This was fixed in an update.

Trivia

 * Both of the final upgrades for the Bloonchipper have "Super" in their names (Super Wide Funnel and Supa-Vac).
 * In Bloons TD Battles Mobile, the Supa-Vac ability can suck M.O.A.B. Class Bloons. However, as of Version 4.1, ZOMGs cannot be affected and BFBs will be affected for 4 seconds to prevent infinite stalling.
 * This (along with Triple Darts) is one of the most nerfed upgrades in Bloons TD Battles Mobile, having been nerfed 4 times via updates.
