What type of actions are the gravewalkers abilities?

[Loren Peterson]

The grave walker archetype witch has some very nice abilities, but it is not very clear as to what action is required to activate them.

Does anyone out there know what action is required to activate

-Aura of desecration (It states that the witch can create the aura implying it does not have to all the time)

-Bonethrall (this states that if the undead fails the save it is controlled as if by command undead, but is forcing the will save the same action as casting command undead)

[Maxximilius]

Correct me if I'm wrong, but unless specified, any capacity like this takes a standard action.

[Kilbourne]

The aura has no upper limit of duration, so can be assumed to be active at all times. However, there is precedence that these abilities can be activated as a standard action, and deactivated as a free action.

The bonethrall ability functions as Command Undead, which means it's an SLA for the witch; it takes a standard action, as the spell does.
