grimoire is for final uncap of SR and SSR Kamihime
i think maybe not worth it yet when already so hard to farm the other exchange item ... maybe next event
I feel like farming the 20 ap is the better choice since 30 ap drop kinda suckssssss
Probably just luck but first time using Billy at high enough lvl to use Lv1 Snatch and manage to use it 3 times before killing Apocalypse, got 2 gold chests which were 2 hearts.
Went ahead and grabbed Apocalypse first just because they give you a crap ton of dark eidolon enhance materials.
Heck yeah! Slipped in under the wire with 5 minutes left before daily reset to get my first Apocalypse. Hope it resets in the next few minutes so I can do it all again :P
