I played a one-shot of Call of Cthulhu where the DM had you roll an intelligence check if you saw a horror. If you rolled over your intelligence, you had no idea what you were looking at and were unaffected. If you rolled under your intelligence, you knew exactly what you were looking at and had to roll against your sanity to see if it drove you insane.

In other words, you could have no idea what you’re looking at, know what you’re looking at but handle it, or know what you’re looking at and not like it!

Por que no los dos?

Privacy badger/possum were welcome sights for me personally.

Granted, but you don’t have a redo option. Once you’ve undone something, you can never redo it.
