Sea Legs

Sea Legs is a buff rewarded from completing the eponymously-named quest immediately after getting shipwrecked in Vashj'ir on Call of Duty (quest).

The buff provides both water-breathing and a movement speed increase. After the quest, players will always have this buff in Vashj'ir and its three zones (of Kelp'thar Forest, the Shimmering Expanse and the Abyssal Depths).

The speed bonus depends on how the player is moving:
 * Swimming above the sea floor has its speed more than doubled, becoming 48% faster than running on land.
 * Running on the sea floor is as fast as apprentice riding on land at 60% faster than running on land.
 * speed is increased to 2.5 times its value in regular waters.
