Way of the Rift Mage

Venatori Tome can be obtained only in Exalted Plains, near the bodies of killed Venatori enemies. The less quests you've completed in the location, the more Agents you will encounter.
Ring Velvet is a quite common material in the game. You can obtain it by killing various enemies as random loot. However, the easiest way to find it is to kill Venatori enemies, so you can look for it when searching for Venatori Tomes in Exalted Plains.
Writing on rift magic can be found near Solas in Skyhold, or bought from a merchant in Val Royeaux.
