So the Orc Scarred Witch Doctor gains the Scarshield ability in place of the 1st-level Hex normally gained by a Witch. There is no action listed to activate the ability. Is it a Standard Action to activate it as per the Hex rules? Or is it something difference since it's not explicitly identified as a "hex"?
At 1st level, a scarred witch doctor learns how to harden her mutilated skin, gaining an enhancement bonus to her natural armor bonus equal to 1/2 her class level (minimum +1). She can use this ability for a number of minutes per day equal to her class level. These minutes do not need to be consecutive but she must spend them in 1-minute increments. This ability replaces the witch’s 1st-level hex.
Unless otherwise noted, using a hex is a standard action that does not provoke an attack of opportunity.
It's a (Su) ability, so it defaults to Standard Action unless stated otherwise.
So it's a standard action.
Even if it isn't being called out as "hex" your typical action cost for a generic SU ability is a standard action.
Thanks guys, didn't know that about Supernaturals ^.^'
