WHERE & HOW TO FARM
Where to farm
The Sudama merchant outside the Hamamatsu Castle Crucible; Yokai Teardrops are obtained from Kappa.
Kappa can drop Yokai Teardrops, and the Sudama outside the Hamamatsu Castle Crucible sells memorandums for this resource. The shop’s listed stock and prices determine what you can buy, so check those before farming or spending. This route is for turning Teardrops into a specific available memorandum; it does not guarantee that every item or price will be present in the shop.
Reach Hamamatsu Castle and the area outside its Crucible.
Have Yokai Teardrops to spend; Kappa are a documented source.
Check the Sudama’s current memorandum stock and listed cost.
Travel to the area outside the Hamamatsu Castle Crucible and locate the Sudama merchant.
Open its shop and inspect the memorandums currently available.
Choose the specific memorandum you need and note its displayed Teardrop cost.
If you have enough Teardrops, buy the memorandum and verify it appears among your acquired items.
If you are short, seek out Kappa in regions or missions you have unlocked and defeat them for possible Teardrop drops.
Return to the Hamamatsu Castle Sudama and check your balance against the listed cost again.
Purchase only the target item, then use the memorandum through its relevant progression menu.
Farming tips
Kappa drops are not guaranteed; collect Teardrops as they appear and use the shop’s cost as your target.
Compare the Hamamatsu Castle merchant’s stock with the Eternal Rift Sudama if the memorandum you want is unavailable here.
Repeat, collect and use
The shop can be revisited to trade additional Teardrops for items it currently offers. Kappa hunting can be repeated, but neither a specific drop nor a particular shop stock is guaranteed.
Common mistakes
Assuming every memorandum is always stocked: inspect the merchant’s current list before farming for a particular purchase.
Spending Teardrops before checking the desired item’s cost: set your target from the displayed price.
Expecting each Kappa to drop a Teardrop: continue the hunt only until you have enough for an available purchase.
When to stop or switch
Stop farming once you can afford the memorandum you want and the Hamamatsu Castle Sudama lists it; switch to the Eternal Rift Sudama if it does not appear here.
