Very similar to this question (Does Warding Bond carry over damage type?), but I can't seem to come to an agreement with one of the other players as this is a different situation.
My character has a shield guardian. If we are both in an AoE poison spell, we both fail the save, does the shield guardian take any damage?
My thought: No. I take 1/2 damage and 1/2 of my poison damage is sent over to the shield guardian. He is immune to poison, and since there is no such thing as untyped damage, he takes no damage.
Other point of view: He takes no damage from the AoE spell, but does take the 1/2 damage from the bond.
What is correct?
