How to buy it
- Progress through the Enchanted Grove/Castle Village Outpost sequence and see event
908079. - Visit the Castle Village Outpost on day 1, 8, 12, 19, or 24 of any season.
- Use Isaac's vendor tile at the outpost and pay 600,000g.
Those five dates come from the loaded Galdora map patch and the in-game Outpost vendor-schedule description. On those days, after event 908079, the patch places an OpenShop FlashShifter.StardewValleyExpandedCP_IsaacVendor action on the vendor tile.
Isaac's separate base NPC schedule file lists days 3, 6, 20, and 23. Those are character movement days, not the shop rotation, so they should not replace the five vendor dates above.
Combat notes
The sword's main advantages are its wide 80–120 damage range, +10 Defense, and built-in 15% critical chance. Normal melee attacks in Stardew Valley do not consume energy, and weapons do not have a durability meter, so critical hits do not “extend weapon life.”
