Elf shaman favored class option:
(Advanced Class Guide pg. 69 (Amazon)): Add 5 feet to the range of a chosen shaman hex. Multiple bonuses from this ability can apply to the same hex, to a maximum of an additional 30 feet for any single hex.
Healing (Su) (Advanced Class Guide pg. 37 (Amazon)): A shaman soothes the wounds of those she touches. This acts as cure light wounds, using the shaman’s caster level. Once a creature has benefited from the healing hex, it cannot benefit from it again for 24 hours. At 5th level, this acts as cure moderate wounds.
Does this increase the range of the healing hex to 5ft and then +5ft up to 30ft? Or does it only apply to hexes with a range greater than touch?
