ITEM DECISION GUIDE
Use verified relationships and acquisition evidence before selling. A listed sell value by itself never proves that an item is disposable.
WHAT IS IT USED FOR?
This is unresolved, not proof that the item has no later use.
Check verified uses →CAN I SAFELY SELL IT?
The database lists a sell value of 95, but no verified safe-to-sell rule.
CAN I GET ANOTHER?
Use the confirmed quest, shop, crafting or fixed-world route rather than an uncertain loot pool.
RELATION CHECK
No verified quest, crafting or choice use is currently linked. The listed sell value of 95 does not prove the item is safe to sell.
