The mirror image spell creates 3 illusory duplicates of the caster, and states that an image vanishes if an attack is directed at it and beats its AC. Does that still work if the attack wouldn't normally do damage?
For example, ray of enfeeblement asks for an attack roll, but it doesn't actually do any damage on a hit. The main problem I have are the two following sentences from the description of mirror image:
A duplicate can be destroyed only by an attack that hits it. It ignores all other damage and effects.
The first sentence says it can be destroyed only by an attack that hits it - but destruction is a thing I associate with damage. The second sentence says it ignores other effects - and ray of enfeeblement causes an effect, not damage.
