Excellent info as always @aleph. Really perceptive that you noticed that sudden change. That you took none element as a reference point deserves to be commended; that has been an oversight in almost all element tests I've read so far. I have some suggestions if you'd like to expand upon these tests: Dark element weapon: since non-interacting elements have influence on the heal strength, perhaps dark element as the opposing element will lower your heal strength? Heal target element: what influence does the armor element of the player you heal have, if any? If this was tested, I'd test it on yourself and on a dummy to see if there are differences between self-heals and healing others. Possible outcomes to take into consideration, using none vs none as reference point: Armor element of the heal target has no effect (which would save a lot of testing, not to mention getting to skip the rest of this post). Higher heals when armors are Light (element matches the skill element). Higher heals when armors are Dark (Dark is weak to Light, so the Light element heal skill will 'hit harder'). Lower heals when armors are Dark (opposite of the heal skill interferes). Some possible outcomes that would be highly unlikely, involving elements other than Dark/Light: Higher heals when the weapon of the healer and the armor of the heal target match (fire vs fire) Higher heals when the weapon of the healer has an element that is strong against the armor element of the heal target (fire vs earth). Lower heals when the weapon element of the healer has a disadvantage against the armor element of the heal target. Another question that comes to mind now they FINALLY made Light boost the heal skills: does the MDEF of the heal target have influence on the heal strength? P.S. this post is way more entertaining to read if you read it as 'heels.' Of course we all want high heels.
