Onslaught is an extensive mod commissioned by developer codetaylor specifically for the Rebirth of the Night modpack. It offers a fully customizable invasion system inspired by the similar mechanism from Terraria.

🔍 Core Features

The mod organizes systematic monster invasions in your world. When an invasion night begins, a visible progress bar appears, and pre-configured mobs begin spawning throughout your server, actively seeking out players. The event concludes when the entire enemy group is eliminated.
