As i recently lvled a mage, i do not have the ability to walk on water, so its really hard to Catch Evermaw.
But i found a way to stay close to him and make full dmg
First of all, you need to kill Cursed Hozen Swabby - NPC - World of Warcraft. They are located south of the timeless island.
Dive down and kill them all, until they drop this Item: Barnacle Encrusted Key - Item - World of Warcraft
They swim around an old sunken ship, swim inside there is a Sunken Treasure - Object - World of Warcraft.
Open it with the Key and you will get this Item: Cursed Swabby Helmet - Item - World of Warcraft
Use it, when you want to kill Evermaw and are near him, you can now easily swim behind him
The Buff last 15 Minutes.
Attention
This Helmet has a 1 HOUR CD and you can't mount when the Buff is active!
While fighting Evermaw, try to swim through the white circles behind him.
They give you a dmg buff![]()
