You can restore max durability of Tuvala gear at any Blacksmith.
Do not use Memory Fragments or Artisan’s Memory. Simply exchange Tuvala Ore for the same base gear and use it to restore your Tuvala gear. NEW SEPT 2021: You can now use Tuvala Ore to restore durability at the blacksmith. No exchanging required!
Some blacksmiths may not have this “facility”. The Velia one located behind the Storage NPC is guaranteed to have it.
Note: Accessories such as belts, rings and necklaces explode on enhancement failure hence max durability cannot be restored. Unless you use cron stones which we strongly DO NOT recommend for Tuvala or Naru as they are easily re-obtainable.
DID YOU KNOW: There’s a chance to get 1 unit of max durability restored whenever your repair your item. You will be notified when this happens “Max durability increased by 1” will flash on your screen. Of course, limited to the item’s maximum limit of durability.
Tip #1: Do weekly quests to get Tuvala Ore or simply grind to get them. Rift’s Echo are also a great way to obtain them
Tip #2: Use Refined Magical Black Stone to enhance from DUO to TRI for non-accessory item and normal failstacks for enhancing from PRI to DUO.
Tip #3: Never restore durability on Naru gear. You will get an extremely large supply of Beginner Black Stones as you do the Mediah questline.
