I was just wonder if you still can move after casting a tervigon catalyst in other units?
The power is used during the Movement phase, so the Tervigon can move either before or after using the power.
About the living battering ram is it +2i then add another +1i for assault bonus and another +1 for AG so total of 5 including its own initiative value?
I'm not sure where you are getting the +1 Initiative assault bonus. If you took Adrenal Glands, they would get +3 to their Initiative in the Assault phase if you charged.
