Related to my other question about this feature.
The Star Spawn Hulk has a feature called Psychic Mirror, which reads:
Psychic Mirror. If the hulk takes psychic damage, each creature within 10 feet of the hulk takes that damage instead; the hulk takes none of the damage.
The Star Spawn Seer, which is commonly present around a Hulk, has attacks that deal psychic damage, clearly meant to be aimed at the Hulk to be dished out (particularly, Psychic Orb which deals 27 (5d10) psychic damage at range).
Say my Seer hits my Hulk with that attack, and there are 3 creatures within 10 feet of the Hulk. How much damage does each creature take? The full 27 (5d10), or is the damage divided among the recipients?
