The Air Blaster in Roblox Slime Defence is typically a knockback-style defense that pushes slimes/enemies backward, helping keep them away from your base rather than dealing the highest raw damage. A related game-page result confirms that “air” blaster-type defenses in this genre are used to push back enemies, especially flying ones.

What it usually does

  • Knocks enemies back when they get close.
  • Buys time for stronger towers or blasters to finish them off.
  • Can be especially useful if the game includes fast waves or enemies that rush straight down a path.

How players usually use it

  • Place it near choke points or tight lanes.
  • Use it as support, not as your main damage source.
  • Pair it with higher-damage defenses so the knockback keeps targets in range longer.

In-game value

  • Best for control and stalling.
  • Less useful if enemies are immune to pushback or if your build already melts waves quickly.
  • Often becomes more valuable in later waves where a few extra seconds matter.

TL;DR

The Air Blaster is mainly a pushback/support defense that helps control enemy movement and protect your base.
