If the caster has a temporary magical effect that increases a stat (like a book from the Amber Temple) does the simulacrum have that boon for the same duration as well, or does it lack the effect, or lack the expiration?

If I'm being affected by a spell or other magical effect, my game statistics and the magical effect are two separate things. The effect of mage armor is part of that spell, for example, not part of me. #DnD https://t.co/a06NHdhacv
