List of mob elemental weakness?

[Sylkis]

There is a rule to what element (and its weakness) a mob is depending on the shards that it drops.
Each mob will drop 3 different shards - you can check this on YG. Now look at the elemental wheel :

----lightning----
Wind------Fire--
Water-----Earth
------Ice-------

Lightning>Water>Earth>Lightning
Wind>Fire>Ice>Wind

The 3 shards that it drop will always be adjacent to each other on the wheel. The element of the mob will be the middle of the 3 elements and so you can determine its weakness.

For example the puk family will drop wind,lightning and water shards regardless of what type of puk it is. Match these to the wheel and you will see that wind is between lightning and water, so puks are of wind element. Their weakness will be Ice.

Look up your mob on YG. Check what shards it drops. Mobs that drop 1 - 6 shards of an element are aligned to that element.

There are mobs that drop 1-6 shards of multiple types , eg puk : http://ffxiv.yg.com/npc/cellar-puk?id=3100109 , so this can't be right.

I have a full list, but unfortunately for you guys, I'm not sharing the whole thing. Since the link I have is to an editable document that was shared in a private section of my LS website, it wouldn't be fair to the author. However, here are a few:

Applying this rule gives this list. Though I've always had my doubts that Efts are water element since they use lightning attacks...perhaps your LS had gotten the info this way.
