Call of Cthulhu vibes here. Some rolls you want to fail, because you’re better off not knowing.

If I’ve got intelligent enemies with ranged attacks they’re absolutely going for that thing once it makes its utility known. Though it’s not like they generally do much with their reactions anyway.

Toss them a minor magic item. Prep while they squabble over who should take it for 30-60 minutes.

In 3 months, you’ll forget they have it and they’ll use it to completely bypass a 4 hour combat you planned, leaving you in the exact fake boat you are now but even worse.

But that’s a problem for future you.
