In one sentence, describe what the following article is about: Every time a character of Elsword successfully changes his/her class, a new combo skill will become available for the players to use. One of the four new combos for High Magician creates an explosion, which can cause more than 200% Magic Damage to enemies within the range based on your character's Mag DMG rate. To execute this combo, the player must press X on their keyboard twice, followed by the Down arrow key and then X two more times. Execution must be done quickly, without being hit by the enemy, which cancels the combo. Fireball is mostly used in PvP because of its no-MP use and the ability to stun enemies, which enables High Magicians to follow their attack with combos or cancel the enemy's combo attack. Tap X on your keyboard twice and the Left arrow key (if your enemy is at the right side of the screen) or right (if the enemy is at the left side of your screen), then press X again. This skill can be spammed, especially if you can execute the combo continuously. This is a simple Fireball Dash compared to the Fireball mentioned above. Instead of throwing two small fireballs before a larger one, Fireball Dash requires you to run then throw one large fireball. This skill is great for escaping from melee players, especially from classes that use Grab. To execute this combo, dash by tapping the Right arrow key twice, then X twice. The High Magician is not just a class for mid-range; they can also do close combat. Expert players use this quite a lot to stun and even juggle enemy players. Tap the Z key twice to attack in close combat and to stun your enemies, and then tap X twice to throw Fireball.
Summary: Activate Explosion. Activate Fireball. Use the Fireball Dash. Hit the enemy with Melee.

In one sentence, describe what the following article is about: Look for the dimensions and weight of your TV in its instruction manual or on its box so you know how much the mount needs to support. Find a mount at an electronics store or online and check the maximum weight and size that it can hold. Opt for a full-motion mount so you can tilt and swivel your TV if you need to make adjustments. Try searching online for your TV's model number followed by "mount" if you want to ensure the mount works with your television. You can usually find the model number on a sticker on the back of the TV or printed on the box. If your TV is lighter than 80 pounds (36kg), you can use a mount that attaches vertically. If your TV weighs more, you'll need a mount that secures horizontally so it evenly distributes the weight. If you plan on watching your TV while sitting in a chair or couch, place it so the center of the screen is around 42 inches (110cm) up from the ground. Search for a place in your room where you can fit the TV so people can watch it from multiple angles. Don't install the TV so high on the wall that you have to tilt your head at more than a 35-degree angle since it can cause neck strain. Ask a helper to hold the TV against your wall so you can trace around it with a pencil. Surround the outline with painter's tape so you can get an idea of how much space the TV takes up. Turn on your stud finder and hold it flat against your wall. Slowly slide the stud finder horizontally across your wall until it beeps or a light blinks. Mark the location of the stud with a pencil before moving the finder over by about 1618 inches (4146cm) so you can locate another stud. If you don't have a stud finder, try knocking on your wall and listen for a solid sound, which means there's a stud behind it. If you hear a hollow or echoing sound, then there isn't a stud. Run the stud finder vertically between the studs of your wall to check if there are any horizontal studs, also known as fire blocks. Try to avoid studs that have a fire block between them underneath the mount since you won't be able to easily fish wires through. You can still mount your TV on the wall if you don't have any studs. Take the section of the mount that attaches to your wall and hold it against the wall so it's perfectly level. Use your nondominant hand to support the mount and find the holes along the top and bottom that line up with the studs. Make dots on your wall that line up with each of the holes so you know where to attach them. If your wall doesn't have studs, choose 3 holes along the top of the mount that are evenly spaced apart and mark them. Then choose 2 evenly spaced holes on the bottom of the mount. If your wall has studs, use a drill bit with a diameter 18 inch (0.32cm) smaller than the diameter of the screws provided with the mount. If you don't have studs, choose a bit that's 14 inch (0.64cm). Hold the drill so the bit is perpendicular to the wall and slowly bore holes through each of your marks. Don't mount your TV without pre-drilling holes first since you could damage your wall. If you have metal studs, use a drill bit that's made for going through metal, or else you could damage or break it. Toggle bolts are hollow fasteners that have hinged ends to hold them securely against the back of the wall. Pinch the hinge closed so it's against the main body of the toggle bolt and slide it through the hole. Push the small plastic ring on the front of the bolt so it's flush with the wall before snapping off the long plastic piece extending out. Put toggle bolts in the rest of the holes. You can buy toggles bolts from your local hardware store. You don't need to use toggle bolts if you have studs in your wall. Hold the mount against your wall so the holes along the top and bottom line up with the holes you just drilled. Feed the screws provided with the mount kit through the holes on the mount and tighten them by hand. Finish tightening the screws with a screwdriver to secure the mount. You may need a hex wrench if the mount uses hex bolts.
Summary:
Choose a wall mount that can support the weight of your TV. Find a spot to mount your TV so it's at your eye level when you watch it. Check the wall with a stud finder to see if there are any studs. Hold the mount against the wall to mark the holes. Pre-drill holes in your wall where you marked them. Slide 14in (0.64cm) toggles bolts into the holes if you don't have studs. Screw the mount into your wall.
