MapleStory Illium Skill Build Guide

February 16, 2024

Illium is a Flora mage that uses ancient magic in MapleStory to deal damage to enemies and boss monsters. If you like a class that can fly, have great mobbing capabilities and is one of the more modern classes in MapleStory, Illium might just be the class for you. Flora classes are the newest race introduced into MapleStory, which are an elf-like species.

Illium Overview

Illium was released in patch V191 Nova: Brilliance Of Illium in December 2017. The class style is built around crystals and tech, and has a skill that it allows it to fly all around maps for a short period of time. Illium has great mobility, especially for a mage class that is usually very reliant on teleport skill. Illium has many skills that allow them to travel across maps much faster, allowing for better map clears and some of the best mobbing in MapleStory.

As a class to train, you'll find Illium one of the easiest. Their mechanics rely on using Radiant Orb and Radiant Javelin in situ, proccing Lucid Brands that increase your damage. You will then have Reaction skills that become active automatically when using the Radiant Orb and Radiant Javelin. Finally, you also get Crystal Skills, which can be used once you charge up Illium's Battery Meter. Crystal placement is one of the areas of training Illium that is very important, as it will allow you to hit more mobs with better placement.

As a bossing class, Illium has been always in the lower end of the scale in terms of damage output. Illium did get some buffs in recent patches that add more boss damage to their skills, but they still tend to need quite a decent amount of funding to hit late end-game (as is the case with most classes). They have a few iframes for dodging one-hit attacks, but for the most part bossing with illium requires keeping your summon up and using the same Radiant Orb and Javelin combo.

You can use a macro for these two skills so that you only have to press one key to activate them. You get the first version of your summon called Ex, that will slowly attack nearby enemies. Lucent Brand is activated when you use both the Radiant skills and that stacks up to 3 times in first job giving some extra damage. Crystalline Wings is your teleport skill and can allow you to fly if you hold it down.
