DM:
We're in Waterdeep, so the entire area is in a magical field, so detect magic is useless.

~~Also you cast a spell and thats a crime in Waterdeep, so you see a Karen of an Elf run off to find the guard~~

Player: I cast Identify on the apples.

DM: first one is fine, second one is a baby Mimic that attacks your finger as soon as you touch it to cast the spell. What's your AC and Roll Initiative.
