Purchasable for 5 royal resin, this will unlock a fourth phero type for all castes who can emit it: raiding pheromones. Raiding pheromones are intended to make raiding fortified locations easier and help speed up fob slogs without having to wait for a king.
Effects are as follows:
+30% Slash and tail stab damage to barricades
-75% damage from barbed wire
-50% damage from sentry guns and mounted machine guns
Simple enough.
