CTRL+U for Rowena’s House of Splendors Check what is actually needed. Start gathering. Don’t forget to turn ON Collector’s Glove. Now the available item is marked as collectable. Click it (raise the chance of obtaining if necessary). Additional menu has appeared. Now appraise the node. You have limited number of actions (similar to crafting) to raise the quality (collectability) of an item. Be careful not to exceed the item’s ware or its gathering chance drops significantly. Now gather an item. Return to Mor Dhona. And pass the item to the marked NPC. “Star” items come from Unspoiled Nodes and can be gathered only on specified Eorzea Time. Normal items can be gathered all the time in the proper region. .
