Back-story
Long before the current events of the Maple World, the Demon Slayer stood as a general for the Black Mage's army. The Slayer had dealt a severe blow on theGoddess of Time, handing Temple of Time to his master. Soon after, the Slayer attends a regular meeting with the other generals. They discuss their duties, and the Slayer learns that Black Mage had ordered the destruction of Leafre, his own home town, even though he had made an agreement with his master as a term for his service. Despite warnings from his fellow officers, he takes off, only to find that his home is left in flames and rubble. The Slayer retrieves the only item surviving the blaze, a locket with a picture of his mother and brother.
Furious, the Slayer travels back to the Temple of Time. Before confronting his master, he tells his subordinate to send a message to the Heroes. The Slayer puts down Arkharium, a fellow general, and storms the now-throne room of the Temple. A heated fight occurs with the Slayer's rage as his motivation, posing as a formidable opponent for the Mage. The battle ended with the Black Mage sealing the Slayer in an egg, confining him to a resentful slumber.
The Demon Slayer awakens many years later, smashing out of his prison. The egg had been improvised as a power source in a Black Wing's base, draining his Fury. Using what was left, he takes down the two Black Wing members watching over him. He notices J in the corner, watching the events unfold. The Slayer, still unsure of the current events, threatens J but succumbs to fatigue. J then brings back the passed-out Slayer to the Resistance base. The Slayer wakes up, still confused about events around him, but joins the Resistance in the hopes of meeting the Black Mage again.
Now the Demon Slayer fights for the Resistance, looking the opportunity to avenge his fallen family.
Gameplay
The Demon Slayer is among the unique classes in Maplestory. The Demon Slayer is the first class that does not possess MP at all. Instead, the Slayers use Demon Fury, which work in different ways than Mana. Along with Demon Fury, they are also more dependent on their HP,even more than Spearman. Most of their skills consume not only their Fury, but their HP as well, so players are advised to watch their health when using their skills. Similar to the Mercedes Benz, Demon Slayers also start off as level 10 after the introduction cutscenes.
The Demon Slayer's weapons of choice are one handed Blunt Weapons and Axes. They are paired with special a Demon Aegis, which grants the Slayers Demon Fury. During gameplay, the Slayers will also recieve unique blunt weapons called Scepters, exclusive to the Demon Slayer class. Players should not switch out their Demon Aegis as the Aegis is their 'Fury reservoir'. Without it, the Slayer would be left with a measly 10 Fury. Along with this restriction, Demon Slayers deal the highest damage using only their respective weapons,making the choice of wielding anything other than a one-handed axe or blunt weapon a poor decision.
Like the Cannon Shooter and Mercedes, Demon Slayers also have a link skill. Their skill allows them to gain an additional 10% boss damage.
- Pros of Demon Fury
- Demon Fury can be recharged easily by using your basic attack.
- More convenient than Mana. As long as the Slayer attacks continuously, they will have a constant stream of Fury. When fighting a tough boss, Mana users will have issues using their skills when they run out of Mana. Demon Slayers do not face this issue.
- Cons of Demon Fury
- There are no potions or items that can replenish the character's Fury or boost your Fury capacity.
- Demon Fury, unlike Mana, does not increase capacity every time the character levels up. The only time the Slayer's Fury increases is whenever they equip an new Demon Aegis, which is acquired upon job advancement.
- There are no scrolls, buffs or Potential which improve Fury capacity.
