At rank 30 it is way too soon to be synthing this item
I would suggest doing hammerhead sharks to sand, or even pikes or ash tuna to sand instead

at around 33-35 applejuice will become much easier to synth so you arent wasting the mats to do it

i have a feeling this is one of those synths thatl get scaled back in its material cost so hopefuly...(even though ill be done with it by then)

also in that range id look into mulled tea if you do alot of botony, switching between the 3 regions and hitting the areas the items drop is an easy way to farm alot of mats for it
