With what I have, I get:
8+2+2.5= 12.5 crit in crystals
5 base
20 skill
--------
37.5 by herself (and with only 2 crystals, dunno what her EX does)
+

+sana 15 +crit damage
+tsuruno 33 (+43 if I had another dupe of her) +crit damage
------
85.5%
then choose either:
>15 crit memoria and I reach 100%
>speed memoria since she's sloooow
>MP charge memoria
>damage memoria

speed can be covered with substats (you need to luckshit both crit% and speed though)
