A quick reminder about the card text before my question:
At the start of the villain turn, Akash'bhuta deals all non-villain targets (H) psychic damage.
If all active heroes take damage this way, destroy this card.
Does the second sentence constantly check to see if the condition is being filled? That is, if all of the heroes take damage this way, does Emtomb get destroyed before it can do damage to other non-villain targets (like golems or all of our ongoings and equipment when Imbued Vitality is out)? Or does it damage everything, then check to see if it happened to damage all of the heroes?
