Rite of Rudiobus

Rite of Rudiobus is a skill used by the Augurs in the Golden Age (Celtic). 
This ability allows your army to move quicker to catch up with enemies. This is important because having a huge speed advantage will allow quicker reinforcements and better charging abilities into battle. 
Summoning this ability will require an animal to sacrifice and lasts for about 45 seconds and cooldowns in 90 seconds.
