What happens if you try to use a Portent die on a roll when the target is not in fact making a roll in the first place? For example:
An enemy casts a spell on my ally (from out of sight, so I can't see exactly what spell is being cast) and I try to use Portent to give my ally a high roll on their save. But it turns out that it's not a spell that allows a save in the first place.
My party is hiding from enemies, and I see enemies looking around, so I try to use Portent to give my enemies a low roll on their Perception check. But it turns out they were only passively looking so were using passive perception, and not making a check at all.
I see in the distance a group of bad guys casting an evil ritual. I'm too far away to make it in time to stop it, but I do have a low Portent die so I use it on them in hopes that they are using some sort of Arcana check to do the ritual and I might be able to make them botch it (of course, they may or may not be making an actual check)
How is this handled?
- Does the die just not get used in that case? Or does it get "wasted". Do you know if it was wasted or if it actually affected a roll?
- How specific do you have to be as to what you are using it on in cases like this? For instance, in example (2), do I have to know exactly which round the perception check is being made (and if I guess wrong it doesn't work) or can I just say "whenever they make a Perception check to try to spot us, I use the Portent die" (assuming I can see them when they make the check) Or in (3), if they were making a check but it turned out it was a Religion check instead of an Arcana check, does that mean the Portent doesn't work because I didn't say what check they were making?
