MapleStory/Monsters

There are many monsters in the world of MapleStory. The most dangerous monsters live deep in dungeons. Harmless monsters tend to stay by towns. Maple Island is one of the places that has very few monsters and are mostly very weak. Higher level monsters live in Victoria Island, but more dangerous monsters live closer to the center (Dungeon) of the island. Ossyria mainly has high level monsters as well as four major bosses. Note that some monsters float, this means that they cannot be struck by low attacks (such as attacks while ducking).

There is also a complete list of monsters, Event Monsters, and bosses.

Items, leftovers, and Mesos
After killing a monster, Mesos or monster leftovers (ETC. items) may be dropped sometimes. However, the monster may also drop something rare (infrequently of course), such as an equipment, which can be worth a lot. The mesos dropped by a monster is varied, and the range varies with the monster (and is usually, but not always, somewhat proportional to the level of the monster, so you will find that in SOME circumstances monsters of same level drops the same range of mesos), the maximum value usually being 1.5x the minimum value. Monster leftovers have many varying uses. Some are used for quests, exchange quests where large numbers can be turned in to an NPC for experience, or for forging materials, such as Firewood that is used to make Processed Wood. In versions with the Maker skill, 100 monster leftovers can be combined to form a "Monster Crystal", an alchemical reagent used to create items.

Crusader Codex
Crusader Codex is essentially a book which every player is given that catalogs monsters. When the Crusader Codex is added to the game, monsters will begin dropping "cards" that contain detailed information on them. Each individual monster's card can be collected only once, within the card has the following details:
 * Availability: JapanMS and GlobalMS
 * 1) The monster's slot in the book lights up and it's standing sprite becomes viewable.
 * 2) The monster's HP and MP values will be displayed, as well as some new animations of the monster, such as walking or knockback.
 * 3) The monster's level will be added.
 * 4) A complete drop list is revealed, with certain items (such as event items) omitted.

Though cards will continue to drop after the card is found, picking up more will not do anything other than give you a message saying you can't pick up more than one. In addition to their permanent change to a player's monster book.

Cards in the book are sorted by relative level range. There are tabs on the side of the book which allow one to skip from level range to level range. The tabs on the book's side are color coded, and the colors match those in the background of the cards which appear in that section. A Chief Gray, for example, has a green background on its' card, and the tab under which it appears is also green. The only exception is cards from Boss monsters, as these appear in a different tab, called "Skull Tab" and has an image of a skull. Certain event monsters also appear as special cards.

Monsters found in Maple Island, Victoria Island, Ossyria, Masteria, Zipangu and Party Quests drop cards. Any other area is not known to drop cards at this time. In certain occasions, you might have already killed a monster before the launch of Crusader Codex and the ability to enter the place to get the card is blocked because of your level range, you may get it through an NPC (for example, in Mushroom Kingdom, the Mushking allows you to get the card if you had already completed the quest before hand).

Sets allow you to get stat bonuses by obtaining cards that the set requires. For example, the set Victoria Island Friends requires you to get Snail, Blue Snail, Red Snail and Shroom to be able to get the set. After getting the cards, you can select the set to be activated in which you will be able to get the bonus as stated.
