Writings of Wonder is a Legendary Tome that produces 2 Troves of Wonders when they are fully charged. Unlike Common Tomes (that can be used as often as you like without cool downs), these tomes can only be used once a week, although, they provide more rewards than Common Tomes per individual use.
Even though they have been removed from the Trove of Wonders, they are still obtainable by rare drop in normal and golden chaos chests.
