Done with the event. Or at least the story and challenge quest. I cleared the challenge quest using that no-fucks-given team above. It’s pretty much just letting Musashi do her NP while Castoria and Proto Merlin being meat shield. I don’t remember exactly how many turns but it was pretty short.
All that’s left for me is farming all the mats and event currencies. Oh and the quest which requires 500 quests completion.
On unrelated note, I forgot to use teapot and thus lost all of them. That sucked.
This event will still be going for two more weeks so there are still plenty of time to farm all the things. Especially void dusts.
