Nether surge

Nether Surges are events during which Nethers group together and attack a safe zone with a Reaper in lead. Players may defeat the Surge to secure the safe zone. After a Nether Surge is defeated, the Nethers will retreat in order to regroup, and attack again. Regrouping is neccesary to the development of a Nether Surge, as sole Nethers will be repelled by the Anti-Nether Devices present at safe zones.
