The paladin is a natural leader. Respected by everyone that knows about these holy persons, they easily make friends amongst the average people of the land. The paladins must absolutely be loyal-good.
Unit: Zealot
Role: Primary fighter / tank, cleric, heavy dammage to undead / evil foes.
Spells: The Paladin's magical powers are granted by his divinity, Pelor. If the Paladin does something that goes against his religion or doesn't pray enough to his god, Pelor might just rid him of his magical powers.

1- Parry - The zealot's shield is brought back to X every Y seconds. Upgrades will augment the amount of shield and reduces the time required to parry again. The paladin cannot attack while shielding. This spell will require some micro to be effective.

Level 2 : Shield set to 66% every 6 seconds.
Level 3 : Shield set to 100% every 5 seconds.

Special- Evil Bane - Kills a number of enemies depending on the paladin's level. Every level, the Paladin receives two points, until the last level, level 20, which means it gets up to 40 points. Every ennemy is worth a number of points (for example, an hydralisk is worth 3 points). When the Paladin casts the spell, enemies around the paladin are killed until the paladin doesn't have enough points to kill more enemies, or none is in the paladin's vicinity. The points are reset after each use of the spell, those points are only used to count how much unit the paladin can kill. The spell costs 50 mana and has a 3 minutes (180 seconds) cooldown.

The Wizard are persons that tend to isolate themselves, it may be because mages are seen like strange persons by the society, or because they need to study most of the time to keep upgrading their magical abilities.
Unit: Dragoon
Role: Support, anti-crowd
Spells: The Wizards doesn't have mana like the other classes, they have a quota of spell they can cast in a day. For example, a level 2 Wizard can cast 4 level 0 spells and one level 1 spell. The level 0 spells are called "Magic Tricks". The spells that remains at the end of the day are lost.
Adittionally, there is many school of magic that the Wizard can attend to. He will be forced to stick to it his life long, so he must chose wisely. The Wizard has access to 9 diffrent spells.

The thief is a fun comrad to have in a party, they are the clowns and money-makers of the gang. If nobody suspects him to be a Thief, he will be took as an average peasant. The Thieves are good scouts but cannot be of any use in a fair fight.
Unit: Unsure
Role: Money / Item Maker, Support

1- Hide - The Thief takes advantage of what he knows about the area to hide. The more time he spends in that area, the easier he can hide here. (DC counting to upgrade the spell's efficiency). The higher the DC, the higher the chance the spell has of being succesfully cast. When succesfully cast, the DM and the player will be allied to eachother and the player will walk slower, this will simulate the effect of invisibility. Re-casting the spell when in effect will disable the invisibility.
Level 1 : Lasts 10 seconds with a 40 seconds cooldown. Min 0%, max 50% chance to succeed.
Level 2 : Lasts 15 seconds with a 40 seconds cooldown. Min 25%, max 75% chance to succeed.
Level 3 : Lasts 20 seconds with a 30 seconds cooldown. Min 50%, max 100% chance to succeed.

2- Pickpocket - When touching a peasant, the Thief can try to steal from him. The spell does not do anything else than giving the thief a few experience points. But the DM knows if the Thief succeded or failed the spell, and can then give money or take whatever action he wants to. Chances to succeed the thieft depends upon the level of the spell.
Level 1 : 50% chance to succeed
Level 2 : 60% chance to succeed
Level 3 : 70% chance to succeed

Level 2 : +200 gas to upgrade armor.
Level 3 : +400 gas to upgrade armor.

4- Throwing knives - Toggle. The Thief can chose if he wants to throw knives at his enemies or not. When throwing knives has been activated, he is going to throw them every once in a while as long as there is an adjacent enemy. The Thief can only carry a set amount of knives, and must buy them to get more. The location to detect the knives is 11x11 tiles big, the knives are represented by Ghosts. Better knives may be bought.

Special- Mach 3 - The Thief uses his unmatched ability to move at unbelievable speed, allowing him to dodge all attacks and attack from everywhere at the same time. Mach 3 makes 5 other exact copies of the Thief and makes him and all the copies invinsible. When the spell worns out, the thief becomes vulnerable again and the copies are removed. The spell lasts 20 seconds and has a 3 mintues (180 seconds) cooldown.

The Assassins uses invisibility to strike their opponents with carefully aimed blows that has a bunch of effects over their enemies. Socially, they like to frighten people, especially defenseless ones. Peasants tend to naturally stay away from these individuals.

The Barbarians, fearless fighters, are natives from the northern ice deserts or the nightmarish southern jungles. Usually half orcs, half humans, they are not seen well in the human society... But the Barbarians' fellow adventurers certainly appreciate the extra muscle brought on the battlefield by the Barbarians.
Unit: Zergling
Role: Primary fighter / tank

Same as the Warrior, the barbarian is not a spell caster, he also has abilities that are not magic, but a few of them needs cooldown or special conditions to be used.
1- Frenzy - The Barbarian attacks so fast that it looks like he got doubles of himself. Creates Devouring ones to fight with the Barbarian, they cannot leave the Barbarian. If the doubles die, they are lost until the spell is cast again. Ability requires 40 seconds cooldown.

Level 1 : 5% chance to bash on attack.
Level 2 : 10% chance to bash on attack.
Level 3 : 15% chance to bash on attack.

3- Instinctive dodging - Passive. The Barbarian's instinct lets him dodge attacks more easily, giving him an armor bonus. (amounts of gas subject to change)
Level 1 : +50 gas to upgrade armor.
Level 2 : +150 gas to upgrade armor.
Level 3 : +300 gas to upgrade armor.

4- Berzerk - The Barbarian enters a bloody rage that makes him attack and walk faster, but this pure rage state makes him unable to parry attack (Devouring one has less armor than the normal zergling)
Level 1 : Transform into a Devouring one for 10 seconds, cannot use other abilities when in Berzerker rage. 60 seconds cooldown.
Level 2 : Transforms into a Devouring one for 20 seconds, the barbarian can use his other abilities. 50 seconds cooldown.
Level 3 : Gives the Barbarian player a spawning pool so he can research his zergling's running speed. The attack speed upgrade can still only be gained while in Berzerk, which now lasts for 30 seconds and has a 80 seconds cooldown.

Special : Northern Demon - Transforms the Barbarian into the great Northern Demon, which can take heavy dammage and deal as much. The Barbarian transforms into an Archon for 30 seconds. The transformation is so brutal that when he comes back to normal, he only has 5% of his maximum HP remaining and walks slower for 20 seconds. The cooldown is 3 minutes (180 seconds).
