Swordmastery manuals unlock new sword techniques and abilities. You need the right manual before a Swordmastery skill can be bought, so loot soldiers, bandits and camp chests.
Kill or loot soldiers and bandits, open bandit camp chests and check sword teachers. Scouting tower chests sometimes hold manuals as well.
Read the manual, then go to a road shrine and spend skill points. Higher ranks cost more points and sometimes time, so check before you confirm.
Magic Manuals
Magic manuals unlock new Witchcraft spells or upgrades. You cannot learn most hexes without the matching manual, so pick up every one you find.
Hidden Treasures
Hidden treasures are buried caches across Vale Sangora, usually found by following a treasure map. They are worth chasing for strong gear, including at least one legendary greatsword.
