Skywrath Mage

Dragonus the Skywrath Mage is a ranged Intelligence hero equipped with tremendously powerful nukes and able to enhance magical damage and to scale into late game. However, he is a glass cannon, while he can bring superb amounts of damage, he is dangerously vulnerable and will most likely to meet a swift end if the player isn't careful. Arcane Bolt is his main spell for damage and its based on his Intelligence level, the more intelligent Dragonus is, the more dangerous Arcane Bolt will be. Concussive Shot blasts the nearest enemy hero, along with nearby units around the foe with magical force, slowing them down. The Ancient Seal marks the target with magic amplification and silence, leaving the target more troubled and vulnerable to magic. Skywrath Mage's ultimate Mystic Flare is one of the most dangerous nukes in the game, but its full power will split equally among enemy heroes within. By creating a field of intense arcane energy, enemy heroes who dare to step in this field will suffer, and it deals all of the potential damage to a lone hero. All of his spells are designed to be used on an enemy hero and not for multiple enemies. From the skies he came, the Skywrath Mage wields the highest form of ethereal magic to annihilate enemies with sheer magical force and once he has the items he needs, none will survive his magical supremacy.

Tips

 * Try to max Arcane Bolt and Ancient Seal first, as the amplification of magic damage couples nicely with arcane bolt's bonus intelligence damage. Ancient Seal also silences your target, so use this to net kills early game.
 * Arcane Bolt deals a lot of damage at level 1 to level 1 heroes. When coupled with Intelligence bonus items like Mantle of Intelligence, even more damage is dealt. The mana cost is also very low, so it's a wonderful harrassment tool. It will also make last-hitting an easy task when you have some good mana regen going.
 * Skywrath Mage is a very squishy hero, so HP items are commonly built. When laning or in a teamfight, try to stay out of range of enemy auto-attacks, and use your skills from a distance, only jumping in when necessary. Force Staff solves this problem easily, allowing a quick escape if danger arises.
 * Mystic Flare is much more efficient on single heroes during ganks, since they receive the full, undistributed damage amount. Try to use this with an ally's stun, however, as the AoE is very small, and very easy to escape out of when not disabled. Using Mystic Flare during a teamfight isn't a bad idea, but it only really works if all the enemies are stunned by a large AoE teamfight Ultimate, such as Magnus's Reverse Polarity. Mystic Flare can be used to kill off the remaining heroes after the stun has been successful.
 * Rod of Atos can be a good early-mid game item, as it gives health and Intelligence: you will be more difficult to kill, and your Arcane Bolt will deal even more damage. Furthermore, the slow can be used to set up a perfect Mystic Flare.
 * You will need to be extremely careful when facing heroes that can deal damage based on your mana pool or intelligence. Examples of this include Pugna's Nether Ward, Anti-Mage's Mana Void and Nyx's Mana Burn. If these heroes are giving you trouble, you may even wish to consider a Black King Bar of your own later in the game to keep you protected from these powerful counters during teamfights.
