Oracle Revelation: Energy body
Is the stated 'move through square' passing bodily through either creature or just next to each other?
If it is passing through each other;
Does the weapon held by oracle also phase into the elemental form?
Should the weapon do so, can the oracle 'strike' other players to heal them? (Case in point Longspear.)
It sounds like a creature needs to move through the actual square the oracle is standing in, so they would need to actually move through where the character is standing.
I think it would be reasonable to allow characters to wave their arm through the square (or have the energy body oracle wave his hand through other squares) to have the healing effect, but I'm not sure that would fly at all tables, consult your GM.
Trying to use a reach weapon to heal sounds like a no go to me, as undead creatures can use a reach weapon to bypass the damage from energy body.
