When Lucian used the Observe Skill he would see the following window that appeared, Lucian getting an alert that his Observe Skill went up in level by one after using it. 

[hider=Minor Air Elemental Observe Data (Level 5)]
Type: Minor Air Elemental

Species: Elemental
Sub-Species: Air Elemental

Lv: 9

HP: 40
MP: 20

A weak form of air elemental. Of the five different elements and the types of elementals, Air Elementals are the most balanced in their qualities and abilities, although sport a bit more swiftness than they do strength. They can project wind to attack foes or slam someone with the wind of its body as if punching a person. Physical damage seems to be half as effective, so magical or metaphysical attacks are recommended. 

As an elemental the five elemental relationships apply to it, so Air Elementals are weak to fire, but strong against earth.

After that he used his Mana Wave skill, the wave like blast of mana firing from his palms and towards the creature, none of the other elementals that even happened to be nearby, as they were all a bit spread out, reacting as this one got attacked.

Damage Dealt: 16

A 16 appeared over its head as the blast slammed into it, seeming to blast away some of the windy essence it was comprised of, Saito seeming to be a bit impressed, Mana Wave's level also going up by one and Lucian receiving an alert for it. "A Mana emission ability... impressive. Somewhat basic and more useful against monsters than real opponents, but still incredibly useful in the fact that no charging or focusing is required." The beast appeared agitated now, seeming to charge towards them, and as it did Saito suddenly began to chant something in a different language.

Lucian Knowledge: 24 - 30 Int = -6

While he wouldn't know what Saito was saying, Lucian would recognize it as greek as Saito chanted the following. "Μπορεί αυτή η μυστηριακή δύναμη πατάξει εχθρό μου! Απόκρυφες πυραύλων!" Suddenly several small, comet like projectiles of glowing, light blue energy shot from his finger, all seeming to hone in on the elemental. Despite all of its efforts to dodge the projectiles all seem to have a homing quality, but also seemed somewhat weak, as they hit spot on. 

An 8, then a seven, then a six, and then a five all appeared over the elemental's head as all four missiles of magical energy struck the creature, each blasting it and making it flail a bit. After that, the HP bar above its head being empty, its essence began to whither and fade away and soon enough it dissipated into a small wisp of wind. After it dissipated a small piece of white crystal was left in its place, Saito looking a bit surprised. "Well...I had my doubts about your power, but after seeing that crystal there...I think they are gone now..." Saito walked over to it, looking down at it, trying to decide whether or not he should touch it. "So... do you have anything that can tell you what this is?"

Around the same time Lucian would also get a PM from Ren. 

[hider=PM]
From: Ren Hitori

Make sure to invite Saito into either our Party or a Party you create so that you can get the full EXP for fighting whatever you are fighting since you would only receive less if he helps you kill them while not in a party with you.
