* Greater Essences that can be equipped simultaneously now stack properly with each other. Previously, a few cases of matching elemental type Greater Essences would sometimes conflict. Now, if you can equip both in the same Focus, you receive the benefits and effects of both Essences.
* Unique-Equip Families have been removed from most Greater Essences; you should now be able to equip any Greater Essences together. Planar Lenses still share a unique-equip family (you can only have one Lens equipped at a time).
Looking over that quote I was curious what people feel is the best greater essence choice for marksman at this point. Assuming you were able to equip two of the exact same ones and they didn't conflict with each other?
