"Even a rat is a better mage than you!"; "Learn the secret of our magic! YOUR death!"; "We don't like intruders!".
Warlocks try to attack their opponents at a distance using their powerful spells. They will run at red health.
The fourth most powerful mage in Tibia and the strongest sorcerer-type monster that is not a boss (equivalent to Infernalist). They will regularly spam you with 2-3 different magic attacks each turn. Besides Great Cloud Beam, Energy Missile and melee, all damage they do is fire damage, even their burst and explosion. Their Fire Field spell is five spaces instead of one, adding one Fire Field in each direction: North, South, East & West.
They are extremely dangerous. They use invisibility very frequently and keep their distance, so it's hard to tell where they are.
Knights should attack them as soon as possible with a two handed weapon since they are weak in Melee and defense. Make sure you trap them in a corner, they can be a real pain when they are running around everywhere. When blocking Warlocks it is normally more efficient to use full offense rather than full defense. Running in their direction and using Groundshaker is a good way to make them visible again, you can also use Whirlwind Throw shortly after they go invisible and they will be visible again.
