I wonder how the Portent ability would work under that system.

Portent is an ability granted to 2nd level wizards in the divination school of magic. At the start of every day, they roll 2 d20s and record the results. They can then use those results on anyone they can see making an attack roll, saving throw or ability check. The target uses the recorded d20 roll instead of rolling themselves.
I’m all for maximum control over reactive abilities (though this one doesn’t technically use a reaction) but Portent would trigger a prompt any time anyone does anything. Is this ability in Solasta? How does it work there?
Similar is true for Bardic Inspiration, although to a lesser extent. Solasta doesn't have divination wizard (or equivalent, I think) as it's not in the 5e basic rules, but such an ability would probably be implemented to prompt for anything (like Paladin's Smite prompts on every attack). I agree this could get annoying.

Best solution is probably to rework this specific ability to make it a free action. Something like:
- If given to an ally: The next time this ally misses an attack or fails a ST/ability check, they instead succeed
- If given to an enemy: The next time this enemy hits an attack or succeeds on a ST/ability check, they instead fail
