How to use Grow Blocker

Grow Blocker stops Regrow Bloons from regrowing while they are inside the Village range. It does not pop anything, and once Bloons leave the circle they regrow normally again.

When to buy it

In standard rounds, Grow Blocker is rarely worth it. The range is small, it deals no damage, and standard games have few rounds where Regrow is the real problem. Druid of the Jungle, Ezili or Cleansing Foam handle Regrow more reliably.

The exceptions:

  • Fights against Lych, which can give Bloons Regrow.
  • Rogue Legends, where Regrow-heavy rounds are more common and an artifact can greatly extend Village range.
  • As the unavoidable first step to Radar Scanner, which is the upgrade most players actually want.

Is it worth it?

Not on its own. Treat it as part of the price of Radar Scanner.
