So, here we have a few new WSs from Mogwai. The first she fires off to close the first darkness SC is Moonlight, which is Distortion aligned. It's Luna's special weaponskill, and is meant to be on par with the weaponskills learned at 225 skill. The second one is Dusk, a combination weaponskill that essentially works as her 230 skill WSNM weaponskill, although it's a bit more powerful as she can only access it every 12 hours. It has Fusion, Distortion, and Darkness elements. In this case, it perpetuated darkness. It requires a shot from both guns, and only works during dusk. It has a partner weaponskill, Dawn, which works with the rising sun and is for the most part similar, except it has Light as the third WS instead of Darkness, as Sol is the rising power.
The SC at the end is a normal darkness skillchain, granted with high power. As the level 2 skillchains are quite obviously combinations of their component parts, the darkness skillchain crumbles, freezes, dissolves, and corrupts all at once.
Also... times like this make me wish I could draw. I got this picture in my head of Mogwai's 4-winged angel of death, dual-wielding guns, 2 wings being demonic bat wings and two as feather (albeit man-made) angelic wings, ready to !@#$%& !@#$%& up. Sadly, she does not smell like cookies.
