How to defeat Yin and Yang together?

[NickMcNate]

I need to defeat my only WAW Abnormalities (which is Yin&Yang) and everytime i try to defeat either the two, my employees get into a panic fighting Yang, and the other die to Yin. Any tips?

Yang must be hit with only melee attackers, were as Yin must be hit with only ranged attackers. Also, like in all fights with WAW classes, shields are your friends and make sure the employees have at least 0.6 (math is required sorry) or better resistance against the WAW abnormality. Keeping this in mind, you can take them out really quickly before the dragon is summoned if they are far apart from each other.

There will probably be a more, probably longer, detailed approach posted from a different user, but I will give you the tiny info I have.
