As You Were

When cast on a dead or undead body, as you were returns that creature to the appearance it had in life while it was healthy and uninjured. The target must havea physical body; the spell fails automatically if the target is normally noncorporeal (banshee, ghost, wraith, et all.).

If as you were is cast on a corpse, its effect is identical to Gentle Repose except that the corpse's appearance is restored to that of a healthy uninjured (albeit dead) person.

If the target is an undead creature, it also is restored to the appearance it had in life, even if it died from disease or from severe wounds, or centuries ago. The target looks, smells, and sounds (if it can talk) as it did in life. Friends and family can tell something is wrong only with a successful Wisdom (Insight) check against your spell save DC, and only if they have reason to be suspicious (knowing the person should be dead is sufficient reason). Spells and abilities that detect undead are also fooled, but the creature remains susceptible to Turn Undead as normal.

This spell doesn't confer speech on undaed that normally can't speak. The creature eats, drinks, and breathes as a living creature does; it can mimic sleep, but it has no more need for it that it had before. Any amount of radiant, necrotic, or Constitution damage immediately ends this spell.

If this spell is cast on an undead careautre that isn't your ally or under your control, it makes a Charisma saving throw to resist the effect.
