Viper/Guide

General

 * Viper can either be played in the off lane with a support, or solo mid.
 * Viper's main purpose in fights is absorbing enemy attacks while whittling them down with his abilities, allowing the rest of his team to act freely. This is an intentionally loose definition since Viper's talents allow him to emphasize damage output or survivability.
 * As a natural result of the hero's design, he excels in prolonged engagements where he can cycle through his abilities multiple times.
 * The hero is flexible in terms of item builds and playstyle. Your item progression largely determines what role Viper will play within the team's overall gameplan.
 * Viper does not need to win the laning stage in order to be a powerhouse in the midgame. In most lane situations, you are better off playing safely rather than exposing yourself to possible ganks.
 * Viper is one of the slowest heroes in the game. This makes him a progressively weaker and more exploitable target as enemy heroes purchase items such as and.
 * Preemptive positioning is key for Viper to have impact in fights.
 * Viper's large assortment of slows allow him to corral less mobile heroes.
 * Viper should be drafted into lineups with multiple disables or itemized in a way that sidesteps the issue altogether.
 * This problem can be partially solved by forcing the enemy to fight you around objectives.


 * Poison Attack is Viper's main tool for harassing opponents in lane.
 * Orb walking is an essential mechanic players must learn to exploit this.
 * This lets Viper attack enemy heroes without drawing creep aggro by clicking on Poison Attack, then attacking an enemy as if you were to cast a spell. This will only produce one Poison Attack boosted auto attack, but it will be more than enough to harass the enemy from time to time in lane without taking damage in return, even with multiple enemy creeps around you.
 * Due to cost and limited opportunity, it is pragmatic to only put 1-2 points into Poison Attack during the early game.
 * Use Poison Attack to slow down fleeing opponents.
 * Use Poison Attack in combination with Viper Strike to kite and control melee carries.
 * Use Poison Attack in combination with Viper Strike to cripple a target's physical DPS.
 * Keep stacking Poison Attack on the enemies to reduce their magic resistance, causing Viper's and allies' abilities to deal more magical damage.
 * More tips needed.


 * Nethertoxin is your primary farming tool.
 * Viper can safely push out waves with its long cast range.
 * With level 3 Nethertoxin, you can clear an entire creep wave while it is clashing with the enemy wave.
 * Viper can farm neutral camps with enough levels in Nethertoxin. The magic resistance reduction and small mana cost makes it easy to clear camps. Additionally, Nethertoxin's break works on creeps. This is particularly useful against the auras provided by ancients, and allows them to be farmed much easier. However, lack of in the early game means this tactic will tax his limited mana pool.
 * When playing Viper in the mid lane, Nethertoxin can be used to easily stack ancient camps without risk of losing farm, assuming you can safely spare the mana. You may consider buying a couple for this purpose. A triple or quad stacked ancient camp easily offsets the cost required to stack, and provides Viper with a quick cash infusion in the mid game.
 * When farming neutral camps, it is recommended to first draw aggro with an attack, then place Nethertoxin near the camp instead of inside it. If properly placed, and with the correct positioning, creeps will spend most of the time moving from the spawn location's aggro box to Viper's location, through the Nethertoxin, allowing him to minimize damage taken while maximizing farm speed.
 * Nethertoxin's break makes Viper a potent counterpick against many heroes that depend on strong passives.
 * The component makes you invaluable against, , , , and several others as long as they stand in its area. Make sure your team possesses enough crowd control to keep them pinned down.
 * More tips needed.


 * Corrosive Skin is the best choice to max first if you and your opponent(s) are trading blows.
 * Corrosive Skin is especially potent against damage over time abilities, like or . Between the magic resistance and continuous reapplication of Corrosive Skin to the enemy caster, Viper will usually take less damage than Corrosive Skin returns.
 * With enough sustain, Viper should take attacks from creeps to apply Corrosive Skin's damage over time, clearing them faster.
 * More tips needed.


 * Viper Strike is one of the best ganking abilities in the early game. Take advantage of it to help teammates win their lanes.
 * Combine Viper Strike with Nethertoxin to dish out immense damage in the midgame.
 * With an early, Viper Strike can be used multiple times in a fight at half the regular mana cost.

Items
Starting items:
 * helps Viper stay in lane.

 * increases attributes and healing with Tango.

Early game:
 * are a standard pickup that give movement speed.

 * adds extra mana regeneration and protection against magical damage.


 * offers burst health and mana.

Mid game:
 * expand his mana pool, allowing him to use abilities more often inside and outside of combat.


 * gives Viper access to a root, greatly enhancing his ganking power, as well as much-needed stats. The components also provide a convenient build up for him in the early game

Late game:
 * , the upgrade to Arcane Boots, make Viper exceptionally tanky. The active restores a large portion of health and mana to the entire team while dispelling debuffs; the passive prevents low health heroes from succumbing to their wounds. The extra survivability keeps Viper alive far longer, allowing him to sustain his allies and deal more damage.


 * enhances his mobility and adds decent stats for reasonable gold.


 * grants debuff immunity so Viper can act without worrying about most enemy disables.


 * is ideal for Viper players who want to frontline. It gives him great stats across the board and the duration of Cold Attack almost perfectly overlaps Poison Attack. The combined attack speed and move speed slows of Viper's abilities and Skadi's modifier will slow any target to a crawl.


 * provides magical damage on top of a solid chunk of damage and a little attack speed. It's best suited against enemy carries who are picking up evasion items and heroes with blind.

Situational items:
 * enhances the magical damage of Viper's entire kit as well as granting attributes and armor.


 * is a good pickup on Viper if you intend to seize map control. Viper is a very capable ganker if he can get close to a target. Between both of his slows and his damage scaling up as his target's health decreases, he is very good at 1v1 dueling.


 * can be an idiosyncratic yet effective choice against teams that rely on damage from 1-2 right-click heroes. Halberd stops those opponents from attacking in addition to granting status resistance and evasion.


 * is a common pickup in the midgame. Viper enjoys the additional health and damage, as well as movement speed.


 * shuts down heroes who rely on items. Viper by nature struggles against mobility items like and ; he is also vulnerable to disables from  and . Nullifier also stops targets from activating,  and other items that counteract his magic damage.


 * provides a mix of tankiness, damage, and chasing potential. Mirror Image dispels certain debuffs that cripple Viper's playstyle. Since Corrosive Skin carries over to illusions, it is moderately useful for split-pushing.


 * is one of the best DPS items for Viper in the lategame. It accentuates his waveclear, adds more magical damage with the active as well as the passive (this damage is greatly amplified under effect of Poison Attack), and provides high attack speed to enhance Poison Attack.Alternatively,if already possessing, should be considered.


 * increases Viper's tankiness. Combined with Corrosive Skin and Guardian Greaves, Viper becomes incredibly hard to put down.


 * prevents spellcasters from using spells, as well as making your targets more vulnerable to your DPS. The mana regeneration also remedies Viper's constant lack of mana.


 * combines well with Viper as he can output high magical damage, specifically from Nethertoxin. The spell lifesteal makes this already tanky hero even harder to kill, and stacks with his spell lifesteal talent to provide significant healing. Extra health and mana also allow Viper to live longer and cast more spells during teamfights. Finally, the cooldown reduction allows for more uses of Nethertoxin and Viper Strike, especially when paired with Aghanim's Scepter.


 * is an item to consider on Viper as he is a durable hero who will survive in fight long enough to deal damage over time to his enemies. Combined with spell lifesteal, it adds to his innate tankiness and the damage also allows him to attack enemies with Poison Attack more effectively.
