Muramasa skill material question

Currently, in NA we got the anniversary event going on and all of the training grounds are open. I’m farming them in order to get materials for Muramasa that is going to come out in January. There is one material I can’t find how to get it’s called Flaming Oni Lantern Plant anyone knows how to get it?

Not in NA yet. Wait for 5.5.


Or use the Pure Prisms (but really no need to right now, just farm them between 5.5 and Muramasa)
