Or SKS for short. Self-buffs RoF, but with too weak stats. Between G43 and M14 you have enough good low-rarity rifles to keep you supplied while you work on better ones.

Good with unique gear and mod3. Less good before digimind evolution. Workable though.

Well EN is now having her special equipment, she can be worth it. Its a very significant boost (Puts her almost on par with NTW for raw ATK stat) and she can 1-shot stuff as an opener pre-skill. She'll be decent but not quite a priority yet.

Of note, she has almost as much ATK as NTW with her chip. This has certain uses to a creative commander.
