I've more or less noticed and tested more than once since well... A year or 2 ago? That Multicasting an ability and that ability being ethereal in damage due to either a buff which makes it ethereal or it being ethereal in nature, against a dragon with Shield of Gold, kills said dragon despite the damage shown in the chat box not even reaching half of said dragon's hp bar.
Example:
Perfect Spell (to be sure it hits), Fusion Burn + Multicast IV + Fiery Strike V (or volcano) against a dragon with 4000 hp shows the following:
Dragon Used Shield of Gold
You used Perfect Spell.
You used Fusion Burn.
You used Multicast IV
You began casting Volcano on Dragon.
Dragon died.
You hit Dragon with Volcano for 2 flame damage
You hit Dragon with Volcano for 7 flame damage
You hit Dragon with Volcano for 10 flame damage
You hit Dragon with Volcano for 200 flame damage
You hit Dragon with Volcano for 400 flame damage
You hit Dragon with Volcano for 800 flame damage
That's 1 419 damage dealt according to the combat log. The Dragon died though.
