D&D 5E Thank God These Spells Changed

Yeah, it seems like such an obvious candidate for scaling. Each extra level could give you one more image.

So play it that way!

For me it does not scale as the ac of the images is low and becomes functionally lower as you level (though not by much bounded accuracy and all) This means it catches attacks that would have missed anyway. It means your fix isnot likely to mess things up.

I would much prefer you roll the target after the hit so I will probably do this as DM. it may make 3rd level worthy though I could just make that a scaling option.
