In one sentence, describe what the following article is about:

This is commonly seen in the PvP ring, especially when you come face to face with a good Code: Exotic user. This combo will release the new class weapon, which is the spear, along with the magic that lunges the enemy into the air before striking them down with spear. Due to the short combo and energy ball that throws enemy in mid air (making them vulnerable), Code: Exotic players tend to execute this repeatedly. To do this combo, press the arrow button twice towards your enemy to run and then press X for the magic ball, followed by Z that unleashes the spear and then repeat. (>> or <<, X, Z) Now that you're enemy is accustomed to your Spear Launcher, they will either try to attack ahead then jump into the air to avoid the energy ball. You can counter this using your Spear Dash where you get to run towards your enemy and then unleash the spear right away. This attack will send your enemy back, knocking them down and give you a chance to connect it with your Spear Launcher combo. To use this, dash towards your enemy and then press 'Z' three times. Per tap, the spears grows bigger and so does the magic damage it causes. (>> or <<, Z, Z, Z). It's unavoidable to have your 'Z' combo canceled because the enemy either found an opening or managed to escape. Spear Riser prevents your opponent from canceling your moves, and on top of that, you can end it with either the two combos mentioned above, depending on the situation.  When you press 'Z' three times, Eve will use her normal combo, but when you press down, followed by two 'Z', Eve will unleash her spear from the ground that will send her enemy flying. The spear will surround her so even if the enemy manage to jump above you, by the time they're about to land behind, they'll be greeted with a spear. Once hit, the enemy will be thrown in the air where they become vulnerable for another set of combo. (Z, Z, Z, Down, Z, Z).

Summary:
Use the Spear Launcher. Use the Spear Dash. Defend using Spear Riser.
