Quest Cheats
In the first Quest, your goal is to buy a potion and a map from Vincent, the priest. You earn gold by killing enemies outside the castle. Vincent's shop is located one room right of where you speak to Wind, the ghost character who helps you defeat Dracula. In the second Quest, the goal is to acquire the Supersonic Punch, an ability you need to defeat monsters. Return to the city of Haze and go to the butcher's shop in the upper left of the city's map. Find the meat hanging from chains in the background and punch it until some ground meat falls. Pick up the ground meat and take it back to Wind.
Kill Cheats
Certain monsters have different weaknesses that hasten the process of killing them. Some monsters "drop" certain items after you kill them, which you need to pick up. Others do not. The most common monsters you encounter are the zombies scattered throughout the game. The slash move, weapons of fire or stone, or holy spells kill zombies and they drop either rotten meat or hobo's clothes. Skeletons weaken under the strike move, the whip or weapons of fire or holy spells. Kill a skeleton and you could pick up the ability to summon other skeletons. To defeat an enemy in axe armor, use the strike move, the whip or an electrical spell. Pick up a copper-plated axe when the axe armor enemy dies.
Boss Cheats
At the end of each level, you fight a battle with one of the "bosses" of that level. Each "boss" has its own weaknesses and strengths so it is important to keep these in mind when fighting. The first is Dullahan, a floating blue undead head that controls a huge headless armor suit. In the battle with Dullahan, use Charlotte's Raging Fire spell. If the armor and head connect, avoid the fast moving projectiles by switching to use Jonathan's character instead. In the Master's Keep level, you face the twin vampire sisters Stella and Loretta. The secret is not to kill them, but to use Charlotte's Sanctuary Spell to make them help you defeat Dracula in the last part of the game.
Nest of Evil Cheats
The Nest of Evil is the seven-level bonus game you can play after beating the main game. Jumping behind most of the bosses on these levels before their major attacks seems to work when you aren't crouching to avoid mid-air attacks or jumping to avoid ground level attacks. The last battle is called Doppleganger, which is essentially you playing as Jonathon fighting yourself. The solution to this battle is actually quite easy. The doppelganger Jonathon enters the battle with your stats. Before entering this battle, take off all your equipment. This lowers your stats to virtually nothing, which the doppelganger copies. Once you begin fighting, put all your equipment on again and you fight an unarmed man.
