Would an attack on a duplicate count as a miss for the Riposte combat maneuver?

Today I learned: Mirror Image triggers Sentinel?! :star_struck

Seems kind of cool from a fiction viewpoint as well. The enemy strikes the illusion putting himself in a position for you to land an vicious attack due to his inability to discern which target is really you.

On the down side.. no reaction for shield, absorb, counterspell

The language is unclear: do you have to redirect the attack if your roll enables you to? Otherwise its useless for Armorers who wouldn't be hit by attacks that would destroy a duplicate?

Can you choose to let an attack hit you instead of your duplicates? For instance, someone attacking me with Magic Missile and letting the attacks hit me and using Shield to negate the damage.

Magic missile is not an attack, and so would not be affected by mirror image.

However, more to your question, I don’t think you can choose where the attack goes. The spell says to roll before the attack is actually made, and that the attack is “directed” at a duplicate if you roll high enough. There is no wording to suggest a choice on your part about using the effect, it just happens.

If an attack hits a duplicate, the duplicate is destroyed. A duplicate can be destroyed only by an attack that hits it. It ignores all other damage and effects.  

Does this mean AoE attacks can destroy multiple duplicates, or that they can only be destroyed by attacks requiring attack rolls?

 

You have to use effects which hit a specific target.

So, unfortunately you couldn’t use fireball to mop them up immediately (although, you might be able to make some progress with Magic Missile).

 

This is relatively viable. You can't directly target a duplicate, you can only target the caster. The four figures occupy the same space, so you might not even see all four at once. For each missile, the caster then rolls to see whether the missile hits them or one of the dupes, adjusting the roll each time a dupe is hit. There's a strong chance you'd take out all three duplicates in one shot. With second level Magic Missile, you'd have a near certainty of taking out all the dupes and also dealing damage to the caster.

Just thinking out loud Magic Missile does not require a "roll to hit" so would it not work like the fireball example? I think it would in my game, but just my thought. 

So just to clarify... If your warlock casts mirror image on turn 1 and then attacks on turn 2, does he just attack once or 4 times since there is 4 duplicates?

Just the one. The images are illusory and the spell doesn't mention any changes to attacks. Mentioning it though, you would think the images would provide at least some benefits to attacking, as they are hiding the true position/duplicating those attacks making it harder to dodge and block.

But its already a pretty powerful spell as it is, it does not need to boost attacks as well. Slight dissonance for the sake of spell balance.

stacks beautifully with blur. thematically and mechanically. images are also blurred and changing an attack's target to a blurred image still lowers the chance of the image actually being hit by said attack, increasing its lifespan.

I wish you could upcast this to get more duplicates

It literally says "A creature is unaffected by this spell if it can't see, if it relies on senses other than sight, such as blindsight, or if it can perceive illusions as false, as with truesight." So unless you want to argue that tremorsense also counts as regular vision, then yeah it wouldn't help. But since everyone else considers tremorsense to not be considered the same as sight, then it ignores these illusory copies.

wouldn't they use ur stats

No concentration! My barbarian is getting this spell

Do I have to buy Tasha's Cauldron of Everything to use this as a bard?

Do the copies cast the spell you cast too?

 They appear to, but since they are just illusions, nothing happens.

ok so i really hope someone see's this. so someone in a campaign im in wants to use mirror image to essentially cast 4 fireballs with one action cause the spell say's the clones mimic your actions i want to knew in what way shape or form is this possible

 it's also worth noting that he plans to accomplish this by making the clones hands solid
