Spell Like Powers always require Activation which means Sacrificing Mana 1. A Creature that can't Sacrifice Mana 1 can't get the benefit of the Spell Like Power.
A Creature can learn a number of Spells and Spell Like Powers equal to its Spirit (Rating).

The Creature can add its Spirit to any Roll! made by it, even if it is Inactive like when it makes Death Saving Throws.

Proficiency
The Creature can add its Proficiency Bonus (Rating) to any time a Challenge would allow a Proficiency Bonus (Rating) to be added.
Since a Proficiency Bonus (Rating) can be added only once it does no good if the Creature already has use of its Proficiency Bonus (Rating).
