Okay So I been thinking on the Assist link feature, I came to realize there so many little actual bond mystery..Even doe most jutsu and etc are rip off the storm series..

So the Assist link idea was the 7 mist swordsmen, Requiring one of these ninja Edo Zabuza/Edo Kushi/Edo Jinpachi/Edo Mangetsu/Edo fuguki/Edo Ameyuri and Edo Jinin. With one of these ninjas can provide for a Assist link being that DLC small cutscene with all 7 mist swordsmen from the storm series.

The requirement would..Example Edo Zabuza and his assist link would need to feature 4 swordsmen from gnw treasure such as the one I mention with of course level 25 Bond and I don't know on the AoE or Singular or how much damage or any status effect.

Sorry I miss a part out..it will be kinda expensive for some.. Considering you would need the swordsmen you wanna run plus 4 other for bond mystery plus a level 25 bond so in total 5 rares you would need.
