Until opponent is Ody or Amakusa....

Yup. When I see that she can increase 2 more NP lv in addition to 2 lv from equipped-CE bonus & bam! A solid 5x Anti-Purge Defense for each frontline member (unless the enemies use some buff-removal effect, it’s pretty solid, I’d say)

Well... so far all Overcharge CEs are only 1 time effect... but with Himiko > Merlin > Brotoria NP chains there will always be 4 silver shields, better go with NP regenerative CEs to maintain the snowball.
