Again, this is another area-of-effect attack, one that'll turn the water surrounding the Mariner bright green. You'll also want to back off from the Tibia Mariner when it raises its weird oar above its head. However, the Tibia Mariner's skeletal soldiers can also be harmed by this attack, so it's actually really good for clearing the way of a few of them. Again, back away from this attack, because it can deal a lot of damage to you if you're caught in the blast. There's also an attack where the Tibia Mariner will make the water around them glow a light purple.

For one, there's a fair few of the buggers to deal with, and once they're actually dead, you'll have to hit them once more when they begin glowing white to stop them from resurrecting. In truth, we'd recommend not making a deliberate effort to slay every skeleton. The Tibia Mariner battle is really a war of attrition, and one that'll test your patience when dealing with the skeletal warriors. For one, this foe continually summons skeleton warriors to protect itself from you, which can be equipped with either spears of crossbows. The Tibia Mariner can be a particularly tricky boss to deal with.
