Ring of the Ram question

[Laran]

Ring of the Ram (p615) does 3d6/action damage to one creature or 9d6 for 3 actions. It says you can also create a cone and target multiple creatures if you use 3 actions.

If you have 4 creatures in the cone, how much damage does each take? A) Do all of them take 9d6,
B) Do you apportion the 9d6 anyway you want
C) Do you apportion the final damage evenly across all creatures?

Do they also all have the same DC?

[Kyrone]

All of them take 9d6 if they fail the Fortitude save DC and yes they all roll against the same DC of the item.
