I am testing the Cleric spell "Guidance" and it appears to do nothing. I am able to cast it and see the buff indicator on the target, but none of the target's stats are enhanced. The game's help screen for the spell states that "Guidance appears on the radial menu, from which one can choose the type of bonus (either to attack rolls, saving throws, or skill checks)." In my experience, no choice is offered and the spell is simply cast at the target. Is there a known bug with this spell or am I not using it properly?
Have you checked the radial menu for the TARGET of the spell? The bonus is added to the next action the target of the spell makes, so the target would need to decide what action to use the bonus for.
