Hell has many types of tortures to put evil beings through. Should your spirit hold strong and survive these demonic trainers and their machinations, you will be, uh... "better" for it. You may train with the Hell Hound, Cerberus, the Ice Demon, the Needle Demon, the Ogre Magi, Dracula, or eat a Fruit of Evil.
Hell, Cerberus-You can learn Fire Element in one day, Bakuriki Demon Blast in four days, or you can go through the Ordeal of Fire which will decrease your PL by 10% BUT will increase your Stamina Modifier by two points. This will take ten days.
Hell, Ice Demon-You can learn Ice Element in one day, Chameleon Meld in two days, Touketsuken in three days, or you can go through the Ordeal of the Ice and earn 15% of your base PL BUT this causes your Stamina Modifier to drop by one point. This will take ten days.
Hell, Needle Demon-You can learn Earth Element in one day, Needle Armor in two days, or Needle Storm in four days. You also have the option of going through the Ordeal of the Needle which will lower your base hit points by 10% for 30 days starting the instant you become alive but you will receive a Needle of Strength which can be used up to ten times during the 30 day period and then afterwards only once for a possible total of 11 uses. This item increases your PL by ten times for the duration of a fight. The Ordeal of the Needle takes 15 days to complete.
Hell, Ogre Magi-You can learn Lightning Element in one day, Rune of Summoning in two days, or Rune of Warding in ten days.
Hell, Dracula-For a semi-permanent evil stain, you can learn ALL the Dead Techniques that require an alignment of -2 or lower to learn in one day. Please note that with the semi-permanent evil stain, you can ALMOST never increase your alignment above -2. The only way to remove the stain is if you use all five wishes of the Darkstar Dragonballs at once. The techniques are as follows: Berserk Rage, Black Mist, Blood Suck, Dark Aura, Kiss of Death, and Raise Dead.
Hell, Fruit of Evil-This Fruit is plentiful in Hell and, wonder of wonders, is free. There is absoutely no discernible difference between one piece and the next until a piece has been eaten. When you decide to eat one of these Fruits, a Manager will roll a die. A roll of 1-4 is a rotten Fruit and you will lose 10% of your PL and be sent to Purgatory for two days. If the die comes up a 5 or 6 you have eaten a ripe Fruit and your PL will be increased by 15%.
Hell, Madness Machinations-Firstly, the Wisdom stat is required to undergo this training. You can twist your own mind for 20 days to reach Madness, a level of your psyche which allows you to learn advanced techniques from any location and reduces the length required to learn them by one day, EVEN WITH WISDOM! Further twisting for an additional ten days will allow you to achieve Chaos, which shortens the length of time required for the following Special Quests by half the required time!
This ability will never leave you unless your alignment reacehes above -3.
