Old Hero Archstone
|1||Approach the fog and watch the cutscene.|
|2||Move to the right to find a building and grab Holy Arrows.|
|3||Proceed along the banks going left to pick up more items.|
|4||Kill the Crystal Lizard on the far end of the area where you can also get Stone of Ephemeral Eyes.|
|5||Approach the center of the area (a little to the left) near the monolith to get Stormruler that you can use to defeat the boss.|
|6||Defeat the Storm Beasts and the Storm King.|
|7||Touch the archstone to get Storm Demon’s Soul and Pure Cloudstone.|
Take out the Storm Beasts first to prevent them from shooting barbed projectiles at you to make targeting the Storm King much easier during the fight.
You can also somewhat reliably avoid incoming projectiles by taking cover behind the house in the monolith forest or the behind the tallest pillar near the center of the boss area.
