What actually EIW cart of DG do??
http://www.cosmicbreak.com/community/forum/topic/5617




I just done tunning my 2nd DG and found this

The Lv10 DG has 2 EIW and the Lv 3 DG dont have any EIW. Yet, DG's stat and AA missile stat still the same.

I will cry if its still the same ; A ;

Spoiler:

You have to click the core and see the stats on bottom right to see the changed stats.
Viewing it by hovering the part views the default stat without any EIW.

I assume you speak of Destructor Girl.

Her Internals give +Ammo, +Speed/+Range(it alternates, one gives speed then the next gives range) for sure.
Possibly +Force and/or -Interval.

In short, Intervals are very useful on DG.
