Glad to see you in Mmooffers. The information in Maplestory from the official forum, we just give it a Summary. We sincerely hope it can help you more or less.
Put cure potions on quickslot or a slot where its near your attack skill like we put Lucky Seven on X, put it on c. hav it near the button. Bring at least the amount of pots for LV4X. 100 White potions 150 mana pills. Aviod attacking chronos by all means of jump shoting. They are pretty annonying even you stand the top part where the sin shoots star for the rat. 700 Damage and 150 damage extra.
Most global players(Maple Story Mesos) have different key sets than msea guys. And using cure pots so quickly is not so urgent, because you almost never get cursed. We would say the best way to defeat alishar is jump attack but its backwards jump attack specifically.
It is pretty complicated but assassin players(MapleStory gold) should understand. When you do a jump atk wait until the peak of the jump to attack with booster of course this is the technique used to attack tall monsters in a mob or the farthest away in a mob. This will probably leave you not being able to move for half a second on the ground but since its a backwards jump attack it keeps you out of the enemy's attack range.
