You cast the spell, and your allies all suddenly appear to be members of the same orc tribe you plan to infiltrate.

This spell functions like reflective disguise, except you can change the appearance of other creatures as well. Affected creatures resume their normal appearances if slain.

An unwilling target can negate the spell's effect on itself by making a successful Will save or with spell resistance.
