Now you can chain easily

im already have lucia... -_-

Nice, now more way to chain

I would suggest you pulling for other units instead of Nivlu if you already have Frederika. Frederika still does have its strengths like barrage, reflex and sharpshoot and should be sufficient for killing or hunting Glaciela and Ildyra.

Nah, i'm gonna pair them up

She's so much better than Fred. Fred doesn't do much against tanks, especially WoL and Engel. Niv tears through them.
