To acquire unique abilities, you need Devotion Points. You can earn Devotion Points by saving your cult's acolytes, who are randomly encountered at skull locations. If you hear the call of higher powers after you arrive in a location, you must hurry to help your fellow acolyte.
Your goal is to protect your ally from an attack by enemy disciples. You will only earn Devotion Points if your allay survives.
You can easily distinguish acolytes from other enemies by their clothing and the weapon they use.
