As we know that Evil Sword is the most powerful sword in TOP2 (but it may not be as powerful as uber gemmed crus or champ swords). Its stats: Min Attack: 1500-1800. Max Attack: 2000-2200. STR: 10. AGI: 10. ACC: 10. CON: 10. SPR: 10. Durability: 600.
So you can see it can be used by any char, any class (including level 1 newbies). But it cannot be repaired, or be fused. Can be traded, deleted, and banked. Its icon and appearance are the same as with the apparel Sword of Cadaver. Miscellaneous: It lasts for 2 hours of use. If the player that has it dies, it's automatically dropped on ground. If durability becomes 0, the item is destroyed.
Crusader or Champ can use it with Illusion Slash, but can't use it with a secondary weapon(tales of pirates II gold). Champ also loses the Blood Bull effect. It can be used with Berserk though, which makes them the fastest classes to attack with it. Voyager has many drawbacks. No skills that affect melee at all. Can't even equip Strike Coral with it. It is the class with lowest attack power when using the weapon compared to other classes.
SS will have the greatest melee attack with it compared to any other class. SS gains attack from Range Mastery and from ACC everywhere (including uber gemmed gloves). Can also use Rousing. Cleric/SM can use it to have 100% accurate attacks with this huge damage (imagine STR clerics/sms). With the buffs, they become even more powerful.
