Blacksmith’s Secret Book
This is an item you can purchase from blacksmith or armor vendors in each town. This item has four versions, which allows you to store failstacks by creating Advice of Valks. Each item shows the maximum number of failstacks it can store. For example, a Blacksmith’s secret book – 20 will allow you to create a single Advice of Valks with up to 20 failstack. Should you have 25 failstacks and use this item, you only get Advice of Valks with 20 failstacks. If you have 15 failstacks and use Blacksmith’s secret book – 20, you get Advice of Valks with 15 failstacks.
