Description
A skill that allows for loading up the erg of a mirage, which has been developed by using mana, on a bow and shooting. This skill can potentially incur great damages on a multitude of enemies. The enemy that is hit with the mirage missile falls into a kind of shock state, as if fallen into a mirage in the middle of a sandy desert. The enemy's HP will fall significantly, and infect any others nearby with the same symptoms. As low as the HP may get, however, it will not fall below 1.

Details
Elf-only skill.
Attacks a single enemy at first, after which that enemy and surrounding enemies will start losing life at a constant rate for a set period of time.
This is known as shock damage.
Upon original impact, arrow damage is applied followed immediately by shock damage.
If the target is killed upon impact, the effect will still spread to surrounding enemies.
If used on a monster that is astride a horse (such as Ruin Guardian), the horse will be infected, too, and vice versa if the horse is hit.
Enemy life cannot fall below 1 as a result of shock damage.
Shock damage does not apply to enemies with Natural Shield level 3.
It can work on levels 1 and 2.
Shock Damage does not stack.
Shock Damage will stack for two different players although.
Shock Damage can not be overwritten.
For example, if there are 5 second left, you can not shoot Mirage Missile again and renew the charge to 15 seconds, you must wait until it expires to have the effect restored.
If you do use Mirage Missile while you already have a Mirage Missile in effect, it will cancel your original Mirage Missile shot, and begin a new effect.
Shock damage is still reduced by defense stats and is completely negated if the target has more defense than damage done by the skill (No number is shown and no damage dealt).
For instance. If a target has 50 defense against rank F Mirage then the target will take no damage and will simply be a "carrier" for the effect, still effecting those around it.
Shock damage will not take effect if the target defends, Similar to level 3 Natural Shield.
Damage from the initial arrow will still connect however.
Loading defense after the shock effect starts will not reduce damage.
The shock damage is calculated for each time it effects a person, not the total.
For example, at Rank F, it will do 10-40 damage every three seconds, for a total of 50-200 damage
The shock effect time and damage go up with higher skill rank. The mana consumption increases as well.
Skill training overlaps. For example, if you perform an attack that fits the "Infect five at once" requirement, it will fill the "Infect four" and "Infect three" etc. at the same time, making training easier.
Infection count only applies to enemies in range that haven't been affected yet.
Number of enemies infected is from initial shot, not total duration.
An enemy carrying the Mirage Missile effect can "infect" other enemies if it moves close enough to them.
Party members and pets will not be affected by the skill.
Aim speed is dependent on the player's Elf Ranged Attack rank, and each shot uses up one arrow.
Using Antidote Potions will not cure Mirage Missile status. It is not considered the same as Poison.
While the skill is loaded, the user may only walk, much like Magnum Shot. You do not have to walk however if you have a Crossbow equipped.
A damage bonus based on player's Intelligence comes in G8.
The skill can be used on and affect other players in PvP, and it can infect anyone, even players who are not in PvP.
If you infect someone in PvP, and an infected person gets withing range to you, you can catch your own infection.

Talk to Castanea about skills to start the quest.
Go out into the desert and find a Giant Stone Statue via Exploration. It is located in the south-western most region of Longa Desert.

Click the statue with empty hands to harvest a "Yellow Heart of Giant Stone Statue". It may take many tries.
Bring this to Castanea. She will give you a "Crystal of Elemental."
The Crystal of Elemental cannot be traded or stored on pets.
Clear Longa Desert Ruins Dungeon (normal) with The Crystal of Elemental in your inventory. Complete the quest after finishing the dungeon to receive the skill.
You can bring a party with you to clear it.
It doesn't matter what you drop as long as you are the leader. (Assuming that you and your party created the dungeon)
