Decoy Image

In order to flush ambushes, you project a duplicate image
of yourself and your companions. This spell creates an
illusion complete with visual images, sounds (including
speech) smells, textures, and temperature. It mimics exactly
what you and any of your allies within 50 feet of you do.
If the terrain differs significantly between that of the
illusion and that of the characters, or if any character takes an
action the illusion can't duplicate (for instance, climbing a
tree if none are present for the illusory duplicate to mimic)
onlookers automatically receive a intelligence saving throw.
In addition, anyone who moves out of the spell's area
disappears from the illusion.
