When playing without Events, what type of Action is Commanding Beasts? Can you use your special rules to modify what the Beasts do?

It is a separate Event Action for each land with Beasts (JE p. 20). A Spirit's special rules generally don't apply, since they usually only affect their Powers in particular or their Spirit Actions in general.
For example, Sharp Fangs Behind the Leaves can move their Presence with the commanded Beasts, since their "Ally of the Beasts" special rule apply when Beasts move for any reason. On the other hand, Many Minds Move as One can't Push Beasts to lands 2 away, since their "Fly Fast as Thought" special rule only applies when they move the Beasts with Spirit Actions, not when Events move Beasts.
