Arc Warden

Zet the Arc Warden is an Agility ranged hero that requires micromanagement and farm to spiral out of control. In the early stages of the game, he is a very powerful nuker. His first ability, Flux, allows Arc Warden to cripple an enemy down and deal large amounts of damage. He and other allied heroes or buildings can be protected from physical attacks with his second ability Magnetic Field, while gaining swift attack speed. Similar to Techies' Land Mines, Arc Warden's third ability, Spark Wraith, allows him to place wraiths that attack when an enemy goes near them, potentially dealing large amounts of magical damage. Finally, thanks to his ultimate, Tempest Double, which allows him to make a perfect copy of himself that can use all of Arc Warden's spells and item abilities, he can spam all of his other abilities and most items twice and easily take down fragile heroes in the early game, or keep himself or his team doubly sustained through certain buffing or healing items. This makes Arc Warden very powerful in both early and late game if given enough farm, from magical nuker to physical carry, or if the time calls it, a very potent support.

Tips

 * Consumables and  can be used by the Tempest Double. Early game, it can be beneficial to keep at least one such item in the inventory and then use the double's consumables on the main hero after creating it, to negate the health/mana cost.
 * The same applies to items with charges such as and . Arc Warden can have potentially unlimited uses of these items if at least 1 charge is kept on the main Arc Warden, then only used it on the Tempest Double. He can also preserve higher duration  by not using it on the main hero, so Tempest Double is always created with a higher duration.
 * Items that place buffs or debuffs can have their duration doubled if timed right, as well as perhaps correcting any mistakes the main Arc Warden has made (such as targeting the wrong unit).
 * Items that place buffs on allies, such as and, can be used on the main Arc Warden for increased protection and then using the main one's own to their allies, or vice versa.
 * The Double can use teleport items such as or . This means while the main Arc Warden is somewhere else, farming, pushing or defending, the Double can be on the opposite side of the map contributing to a gank or farm the enemy jungle easily.
 * Using Hand of Midas with the Double grants the player the gold and 2.5x experience. The double maintains the Midas cooldown while it is unsummoned. This means that the double will not be able to Midas every summon and Arc Warden must wait to summon the double to get the full benefits of the extra Midas.
 * One Hand of Midas on the hero results in (190/100*60=)114 gold per minute if used whenever it is off cooldown. For the Tempest Double, the gold per minute is (190/100*60=) 114 gold per minute, resulting in 228 gold per minute for the player when both are always used when off cooldown, 2 times more than other hero with one purchased Midas.
 * It is wise to use the Double to farm or stack neutral camps if it has nothing else to do with its remaining duration for more efficiency and to gain more gold and experience.
 * 's incredible range means it can be used for many different purposes. For one, it can be used to scout areas that may be too dangerous to just breach with the main hero, or stack multiple creep camps from a distance if timed right. Its cast range is even higher than most blink distances, making it possible to still catch enemies with escape abilities.
 * Since the Wraith has a delay upon cast before being able to attack, it should be placed into the enemy's path when chasing an enemy. This either forces the target to chose another, probably more dangerous path, or causes it to take damage and be slowed. Thanks to the spell's low cooldown, this can be repeated often. This can also be done to escape when being chased, by placing the wraith in front of oneself.
 * Stacking Spark Wraiths in an area can be a good ambush technique, very akin to and their . Since enemies can see Spark Wraiths, hiding them behind trees or in cliffs may be necessary. Since they are not considered actual units, they can be placed literally anywhere on the map.
 * Applying on an enemy first before summoning a Spark Wraith can make hitting the enemy with it easier.
 * The Tempest Double is not an illusion, therefore it does not take bonus damage from, nor are they killed by or Roshan.
 * fully affects buildings, so it can and should be used to deter a push.
 * Keep in mind that True Strike does not work against buildings, so even if the enemy obtains a, towers would still be fully protected with this spell.
 * While cannot be used by the Tempest Double, it does allow the summoning of another Double. If done right, this could mean an item could be used four times (once by the main Arc Warden, once by the first Double, refreshed, used again by the main Arc Warden, then once more by the second Double).
 * It is very important to not allow an enemy to steal Tempest Double, since the ability fully works for Rubick. As Tempest Double is the only ability which the doubles have already on cooldown when summoned, this means  is completely available to use for a Rubick Double, fully able to steal and cast a spell as the same way the original Rubick. Wisely managed and well timed, Rubick and his doubles can steal and cast important ultimates such as  or  with ease.

Trivia

 * The line arcwar_kill_12.mp3 "You will just have to accept this, and move on." is a reference to a Dota 2 based web cartoon The Dota 2 Reporter, where it is a recurring gag for the characters to question the game's logic, only to be answered by this line.
 * The lines arcwar_attack_15.mp3 "Doggedly." and arcwar_move_22.mp3 "Hounding." are references to Arc Warden's former appearance in WC3 Dota, where his model was that of a Gnoll, a canine-like creature from Warcraft. His rivalry lines towards arcwar_rival_20.mp3 "Inferior form." and arcwar_rival_21.mp3 "Apex predator, you are not. " are also a nudge to this.
