How To Guides

Protection against Unsuccessful Scrolling with Shields

Using a Shielding Ward on a piece of equipment protects it from being destroyed by scrolls that have a chance to do so.

• Purchase a Shielding Ward from the Cash Shop, and move it into your item inventory.
• After leaving the Cash Shop, open your item inventory and your equipment inventory.
• Drag the Shielding Ward from the Cash tab of your item inventory and drop it onto the item you want to protect in your equip inventory. A shield icon will then appear on the corner of the item’s icon.
• Go to the Use tab of your item inventory, drag a scroll that has a chance to destroy an item if it fails, and drop it onto the shielded item (the scroll must be labeled as being able to work on that type of item).
• If the scroll fails, your item won’t be destroyed!
• The Shielding Ward’s protection will be used up whether or not the upgrade scroll was successful.
  Shielding Wards cannot be used on items that have been successfully enhanced to twelve or more stars. In the Legends update, the limit was increased from the previous eight.

Using a Shield Scroll on a piece of equipment protects it from having its available upgrade count reduced by a failed scroll.

• Purchase a Shield Scroll from the Cash Shop, and move it into your item inventory.
• After leaving the Cash Shop, open your item inventory and your equipment inventory.
• Drag the Shield Scroll from the Cash tab of your item inventory and drop it onto the item you want to protect in your equip inventory. A message will appear in the item’s description that upgrade slot protection is active.
• Go to the Use tab of your item inventory and drag a scroll and drop it onto the shielded item (the scroll must be labeled as being able to work on that type of item).
• If the scroll fails, an upgrade slot won’t be used!
• The Shield Scroll’s protection will be used up whether or not the upgrade scroll was successful.
  You can use both of these scrolls on an item for maximum protection when using upgrade scrolls.
