finish mork dungeon, the jotun advance: valheim deep north

in retrospect, you can just float down to the bottom and smash the quest item, then grapple back up, if you choose. so, consider how much you really want to loot the dungeon. also, while this has never happened to me, be careful about trying to grapple or float for long sections if there are active hexen (flying mages). while floating is generally invulnerability against most enemies, hexen have basically a hitscan shout attack which could disrupt your air movement.
