Lore & Bio

"You've failed the acid test."

In the deep dark caverns of the Nether Reaches, there is a race of flying reptiles ,which is called Netherdrakes, and has been living there for several eras since the tectonic shift happened and trapped them inside. This race is famous for their powerful poison and acids that can melt away any metals. And among the race, Viper is the well known Netherdrake as his desire for dark magics. Although the door to the outside world was closed millions of years ago, he somehow managed to free himself and get out of the Nether Reaches. By then, this deadly creature was captured by the elderly mage who wanted to tame and kept him as a pet. 

As the craving for magic was so strong, Viper obeyed and succumbed to the master in order to learn the spells. But soon, he was fully aware of how powerful his toxins are, comparing to the few spells. The acid drooling from Viper quickly melted down the metal cages, he sprung out of the control of his master, spitted the poison right in the eye of the old spellcaster and flew away as a sign to the world that he had a new master.

viper masterdota guide

In-game, Viper is described as: 

“Launching deadly poison from a distance, Viper poses a grave threat to whomever he targets. As his various toxins eat away at an enemy's health and slow their movement, Viper simply does what he does best: he keeps adding more poison.”

Skills building guide

viper abilities dota 2

In this build I will focus on guiding you how to play Viper in the mid lane. For level 1, we should add one point in Nethertoxin as It is useful to clear the creeps quickly and to harass if the opponent is a melee hero. Then the first ability I recommend you max out is Poison Attack as it increases both magical and physical damage amount.Besides, the slow effect can be useful while chasing the enemy. Also, in the laning phase, you can easily harass the enemy heroes.

The second ability to max out is Corrosive Skin due to the magical resistance it grants and the DPS damage and slow debuff it can cause. Nethertoxin is your last priority. Although this ability is great and useful due to the AoE and DPS damage it can cause, it is really easy to dodge and get out so you should place only one point on this skill in the early game.

Besides, Bad Suju reduces the armor on the enemy which makes Viper’s attack deal more damage.

Drow Ranger

Drow Ranger: the great attack speed granted by Precision Aura makes Viper difficult to handle in his laning phase. There is nearly no chance for the enemy to run away when Drow Ranger casts Gust and Frost Arrow in combination with Viper’s slow debuff abilities. Corrosive Skin allows Viper to tank while Drow Ranger deals damage in the back line.

Earth Spirit

Without the help and distraction from Viper, Lich can’t cast his abilities in the teamfight due to his lack of mobility.

Necrophos

Viper can take advantage of the small amount of health healed by Death Pulse. Besides, Necrophos’s common items also synergize well with Viper’s abilities such as Radiance, Veil of Discord and Guardian Greaves.

Ogre Magi

Chaos Knight

Chaos Knight: Just in the blink of an eye, Viper is stunned and drawn close to Chaos Knight when he casts Chaos Bolt and Reality Rift respectively which leave Viper no room to react. The high damage output from Phantasm and Chaos Strike can grant Viper an instant death.

Invoker

Invoker: Ice Wall and Ghost Walk are tools for Invoker to kite Viper or slow him down when escaping. Chaos Meteor and Sun Strike can kill Viper quickly due to the high damage they can deal.

Forge Spirit melting Viper’s armor which makes him more vulnerable in the combat or teamfight.

Morphling

Morphling can run away or escape from Viper by casting Wave Form. The huge amount of health Morphling attains when casting Attribute Shift (Strength Gain) make Viper’s DPS hardly affected. Morphling can morph into Viper and use his own ability against him.

Lifestealer

Lifestealer: Viper Strike deals zero damage on Lifestealer when he casts Rage. However, the slow and spell immunity pierce debuffs still affect Lifestealer. Feast and Open Wound can help Lifestealer survive the DPS from Viper when dueling.

Phantom Lancer

Phantom Lancer: with many illusions created by Spirit Lance and Doppelganger, Viper is confused and hard to handle because his skills mostly are single target (except Nethertoxin). The slow debuff from Viper is totally useless when Phantom Lancer casts Phantom Rush to approach him.

Pugna

Nether Ward forces Viper to be more prudent when casting spells as the more spells he casts the larger the damage he receives. As having no tool to disable the channeling ability so Viper can not resist when Pugna uses Life Drain. 

Rubick

Rubick is notorious for stealing opponent’s abilities so Viper will have a hard time dueling with him. As Nethertoxin can disable the passive so Rubick steals it by casting Spell Steal and uses it to deactivate the Corrosive Skin of Viper. He can also steal Viper Strike to weaken the main carry in combat.

Terrorblade

Terrorblade: swaps HP with Viper by casting Sunder can turn the table around and put Viper in the dangerous situation. Viper will be vaporized quickly when Terrorblade is under Metamorphosis.

Weaver

Weaver: With the help from Shukuchi, Viper can’t slow Weaver. Time Lapse will make all the DPS caused by Viper become useless and undoes poison damage.

Windranger

WindRanger: When Winrun is activating, the projectile from Viper can not cause damage and debuff on Windranger. With low mobility, Viper struggles from dodging Shackleshot and Powershot.

Wraith King

Wraith King: Viper can’t stand the high burst damage from Wraith King.

Items Counter

Favorable Matchups

Game plan

Early game

Farming,farming and farming are Viper priority in the early game. Use Nethertoxin to weaken the creeps,Poison attack to last hit the creep, harass the enemies and prevent them from farming. If you are dueling with a mobility hero in your lane, try to hold your position to farm and wait for the jungle or supporter to help you secure the skill. When clearing the creep wave, you can start to roam to another lane to gank if you see the sign of that in the mini map.

Mid game

Your priority is still farming but be ready to engage in any imminent fights.Due to the low mobility you should start to move when you sense where the fight can happen and be one leg ahead. Make sure you only do that when clearing up the creep waves in your lane or winning your lane. Immediately go back to your lane when finishing the gank to maximize the efficiency and destroy the wards on your way back to the lane if possible.

Late game

Your objectives in the late game are quite the same with the mid game but this time you and your team might play around the keys objectives like Roshan and towers. As you are a great source of DPS so finding a good position to cast spells is a must. The longer you stay in the teamfight the more damage you are going to deal. And remember any winning teamfight in the late game can lead to the victory in the end.
