Trickery Domain cast spell

Trickery Domain can cast a spell from the position of its illusion starting at level 3. I figured out the Word of Radiance spell from the illusion's position, but is it possible to cast True Strike from the same position? In other words, will I be able to conditionally strike from the illusion's position? It just sounds silly, and it probably shouldn't be done according to RAI, but if I were a RAW and RAF master, I would allow it. It's literally an echo knight for 5.5

I apologize for my English, I used a translator

I don't see why it wouldn't work.

Using Invoke Duplicity for spells like True Strike, Booming Blade, or Green-Flame Blade (they're similar, really) is debatable, because your duplicate friend doesn't have any real weapon in their hands.

Most people rule it's not allowed (me included). But I'd recommend asking your DM, because Invoke Duplicity (or a similar feature like Gaze of Two Minds) are tricky features and can have a different interpretation or ruling.

Some threads I remember about this topic:

- Warlock Gaze of Two Minds questions

- RAW/RAI - Invoke Duplicity + Wrath of the Sea (since comment #15)

- 5e Trickery Domain Cleric Question

EDIT: for clarity.

Yeah, technically I don't think the rules have any provisions for spells which you CAN'T cast through the duplicate... but if I was DM'ing it, I would not allow concentration-based emanations like Spirit Guardians because the duplicate isn't itself a creature. Word of Radiance I would allow through the duplicate because the duration is instantaneous. I would not allow True Strike to work either because the duplicate has no substance and can't hold an actual weapon to do the weapon attack part of the spell.
