 * Scavenger Hunt: Wolf School Gear Upgrade Diagrams - Part 6

Journal entry

 * ''Some of the improvements to School of the Wolf gear are hidden in the Skellige Isles. Elgar left them in the central part of Ard Skellig and in the ruins of two watchtowers: one on Undvik, one on Spikeroog. He wanted them to be available for witchers who need them and are clever enough to find them.
