Skillchains diagram

This simple diagram represents interaction of elements, when they are able to generate skillchains.
Only adjacent elements are able to create skillchain. Boundary elements interact in opposite directions, if other order isn't pointed by a needle. The second element determines the nature of skillchain.
For example, element of the fire interacts with element of the earth, forming the first level skillchain "Scission". Under the opposite order, element of the earth interacts with element of the fire, forming the first level skillchain "Liquefaction". The needle shows the order of interplay for element of the water and element of the thunder: element of the water interacts with element of the thunder, forming the first level skillchain "Impaction". 
There are such interactions of elements, which create skillchain of the second level. And in this case, the nature of skillchain is determined by the second element. The two-colored circle is placed in area of this element and shows the form of skillchain.
So, element of the fire interacts with element of the thunder, forming the second level skillchain "Fusion".
Finally, the third level skillchain is formed of interaction of two skillchains of the second level. The circular arrow shows a direction of interplay; coloration of the arrow fixes the nature of skillchain.
Notice: utilization of this diagram supposes good knowledge of an elemental's attack (weapon skill) or presence of some observation lol♫
