In Icewind Dale it was a Loris. No other text was changed.

The question of fog/darkness/beaded curtains is an interesting one, thanks for bringing that to my attention, would have co. I wouldn’t rule darkness as being superior to fog cloud (provided they’re both silent images) Both will be dispelled by physical interaction.

When I explained my ruling a clever player asked all physical interaction. I overconfidently answered affirmatively, and they said “what about precipitation?” LOL. House rule, rain reveals it for viewers within 10 feet, snow for viewers within 20. Only minor illusion, silent image can fake the interaction.

Solid argument, you’ve just changed my ruling!

I try to keep npc reactions to solid-snaking pc’s appropriately tiered:

• Apparate a crate over yourself while in melee? First enemy attack is disadvantage, second straight.
• Apparate a crate to hide in a PC’s house? Definitely getting investigated on sight.
• Apparate a crate in a packed warehouse - likely to go unnoticed.
