I'm looking at the option of storing Simulacrum in an 8th-level Glyph of Warding. My question is how it will determine what creature gets duplicated.

Simulacrum says:

You shape an illusory duplicate of one beast or humanoid that is within range for the entire casting time of the spell.

Glyph of Warding says:

If the spell has a target, it targets the creature that triggered the glyph.

I'm not sure if the quoted section of Simulacrum counts as "targeting a creature". I could basically see two ways this plays out, and I'm not sure which way it should go:

  1. You store Simulacrum, targeting yourself, in Glyph of Warding. Whenever the glyph is triggered, it summons a simulacra of yourself as you were when you inscribed the glyph.

  2. You store Simulacrum in a Glyph of Warding. When the glyph is triggered, it "targets" and summons a copy of the creature who triggered the glyph. If they are a valid target (humanoid or beast) it creates a simulacra of the target in the state they were in when the glyph was triggered.

Which interpretation is correct?


Simulacrum explicitly targets a beast or humanoid. Simulacrum is an eligible spell to store in a Glyph of Warding, because it's a spell that targets a creature.

The spell must target a single creature or an area.

The target is selected when the spell is being cast. A spell stored into a Glyph of Warding is not "cast" until the Glyph is activated.

When the glyph is triggered, the stored spell is cast.

The Glyph would "target" the creature stepping on the Glyph and create a duplicate of that creature.

Normally, a Simulacrum is friendly to the caster and the creatures that he designates. The problem is, does the creature storing the Simulacrum spell "cast" it, or does the Glyph "cast" it? This is up to DM interpretation though I would lean towards the latter because of the way that Glyph interacts with other summon spells (i.e. - they don't obey the glyph caster).

If the individual can be said to cast it, the Simulacrum is friendly to the caster. If the Glyph casts it, the Simulacrum is not friendly to the caster, and the spell is mute as to what the Simulacrum does (though presumably, it would have the statistics of the creature that it duplicates, which would include languages, mental statistics, proficiencies, etc.). Beyond this, it is up to the DM.

    \$\begingroup\$ I love the thought of the glyph casting the spell, creating a duplicate of whoever triggered it, but friendly to the caster of the glyph! Suddenly you find yourself fighting yourself! \$\endgroup\$
