The 4th level is ready. You descend into the dungeon where all the prisoners have been set free from their cells. Three new enemy types await you: a thief, a bandit and an assassin.
The thief tries to jump on your back. If he succeeds, he starts stealing away all the items from your inventory. If he finds a bomb, he will immediately use it. You can knock him off if you use a rage attack, or find some way to hit him - including meteors, bouncing orbs or via a voodoo doll. Also, if anything knocks you down, he will fall off as well. The thieves use a curved dagger, which is a new weapon with a throwing attack and backstab damage bonus that you can also use yourself.
The bandit is quick and uses a Morning Star that does a lot of damage. You also use this weapon if they drop it. The bandits will try to surround you from two sides, so watch them carefully.
Assassins have a short poisonous sword and a shield. They move and attack similar to the castle Guard Captains, but poison attack makes them really dangerous.
To counter all the shielded enemies, there's a new weapon in the game: The Excalibur. You can sometimes find this legendary sword in a forest, stuck in a rock. Once you retrieve it, you can cut through enemy shields as if they weren't holding any.
The dungeon features a new level style, with a couple of new trap types, a new treasure chest type and new music theme as well.
