Leshrac/Guide

General

 * One of Leshrac's greatest weaknesses is his long cast animations. In order to counteract this, good positioning and prediction are key, as Leshrac must stand still for an extended period of time before the spell takes its effect.
 * While Leshrac has tremendous nuking power, much of it is damage over time, requiring him to survive long enough to cast multiple iterations. As such, not only is a large mana pool required in order to sustain such casting, but also enough HP to avoid dying to the enemy while casting.
 * Mind that because the vast majority of Leshrac's damage output is magical damage, he can be easily countered by spell immunity, and his frailty allows enemies to use his damage against him via . If Leshrac is to be effective in teamfights, he must focus on disabling enemies to prevent them from activating spell immunity, and build spell immunity himself both to increase his survivability and block Blade Mail damage.
 * Leshrac can usually be played as a core or a support.
 * Played as a support, Leshrac has powerful disables that can greatly aid his team in fights, and can deal tremendous damage to enemy towers as well. His nuking spells also allow him to obtain gold fairly reliably for buying more support items. A support Leshrac should focus on purchasing utility items to aid his team in fights.
 * Played as a core, Leshrac has tremendous pushing and nuking power that can allow him to deal large amounts of damage in teamfights, or push lanes and take towers by himself. Once he has enough mana, he can use his nuking spells to farm very effectively as well. Core Leshrac should aim to build items that enhance his survivability and casting, as he must stay alive in order to put out the damage to kill enemies, and requires steady mana regeneration in order to fuel his costly and low-cooldown spells.
 * All of Leshrac's spells have differing priorities to max out depending on his farm priority, team lineup and expected opposition. There is no one-size-fits-all build, as certain abilities may greatly synergize with those of allies, cover for their weaknesses, or exploit a flaw in the enemy's lineup.


 * is a ground-targeted spell that stuns enemies within its radius while dealing damage.
 * Split Earth will stun any targets it hits for 2 seconds, no matter how many levels were put into the spell. Therefore, it should be leveled up if you need the wider radius to make hitting the spell easier, or the increased damage.
 * Remember that the stun's effect occurs 0.35 seconds after the cast animation, so it will stun and damage roughly one second after Leshrac is commanded to cast the spell. If an enemy is watching your cast animations to predict when the stun will land, they can dodge its effects with certain spells (such as or ). Therefore, if landing the stun without a leading disable, it can be useful to cancel the animation mid-way to fake out tricky opponents.
 * When using Split Earth as a support, it is best to only put one point into it early on and have a teammate lead with a reliable targeted stun first. If an enemy has been immobilized by a stun, they cannot move to avoid Split Earth and the long cast animation and small effect radius do not matter. This way, you can chain-stun an opponent and spend your skill points on your other nuking spells.


 * causes physical damage explosions to surround Leshrac once casted, targeting any enemies near Leshrac and following him as he moves.
 * Edict deals tremendous amounts of damage if all the explosions land on a single target. It is best used after other enemy targets in the area, especially creeps, have been cleared away by your other spells, in order to make the most of its effects.
 * Diabolic Edict is what allows Leshrac to destroy towers so quickly by himself if he is left alone by the enemy team. A single cast of level 4 Diabolic Edict can deal 940 damage to a tier 1 tower, after reductions, which alone is enough to bring it below 30% HP (not including any creeps and siege units also attacking the tower). If pushing down the enemy's towers early on is a priority, consider maxing out Edict first.
 * Try to keep Diabolic Edict in reserve when attacking a tower, as the enemy may immediately use their Glyph of Fortification when they see you cast Edict. Try to force the enemy to fortify their towers, and then cast Edict afterward to deal the most damage possible.
 * The explosions follow Leshrac, and are focused on a radius around him, so even if there are enemy creeps near a tower it is possible to re-position Leshrac so that the tower is within the spell's radius but the enemy creeps are not. This also allows Leshrac to chase enemy heroes with the spell after casting it, as they will automatically hit any enemies that he is walking next to.
 * Keep in mind that the explosions will still home in on invisible units if they are within the radius of the spell, and as such can be used as a weak form of detection. This means that Edict can be used as a counter against abilities such as, , , and so on.


 * is a low-cooldown unit-targeted spell that damages and slows its target, then jumps to other nearby enemies.
 * Lightning Storm is a strong farming and wave-clearing spell, as its low cooldown and area targeted nature allows Leshrac to deal large amounts of magical damage in a short amount of time.
 * Lightning Storm is the perfect complement to Diabolic Edict, as the spell's nuking power and low cooldown can make short work of lane creeps, allowing Diabolic Edict to be focused on the enemy's tower alone. As well, it can be used as a leading slow on an enemy prior to casting Split Earth.
 * Try to take advantage of Lightning Storm's long cast range and ability to bounce. It can be a powerful harassing spell as Leshrac can hit a creep with the spell and allow it to bounce to the enemy hero.


 * deals tremendous amounts of damage to all nearby enemies, and is a toggled spell that does not require a cast animation. It is a powerful spell to use when chasing or fleeing, especially alongside Diabolic Edict, as it can remain active while moving, allowing Leshrac to run down foes or discourage them from chasing him.
 * Keep in mind, Pulse Nova requires Leshrac to stand very close to the targets he wishes to damage. If you intend on using Pulse Nova in team fights, survivability items that boost Leshrac's HP are highly recommended.
 * Note that since Pulse Nova can be toggled, it can also be used as a farming spell by turning it on while farming creep waves or jungle camps, adding to your nuking power.
 * Since the first damage instance is dealt immediately upon toggling the spell on, the damage per second of Pulse Nova can be increased by constantly toggling it off then on after every two damage instances. However, the cost of this tactic is a significantly higher mana cost due to incurring the toggle cost multiple times, so ensure that Leshrac's mana pool is sufficient to support it.

Items
Starting items:
 * and are generally the minimum amount of regen needed no matter what position is being played.

 * gives Leshrac additional strength, which increases the size of his HP pool, and prevents him from being disabled, allowing him to get within close proximity to damage the enemy with his spells. As a core, it provides Leshrac with immense survivability against disables and any burst magic nukes the enemy may have, as well as immunity against Blade Mail.

 * enhances Leshrac's survivability against physical damage while also increasing his mana pool.

 * Be sure to upgrade to the as soon as possible when playing as a support. Giving your carries faster access to their needed items is essential in the early game.
 * is very powerful on heroes with low-cooldown burst magic nukes, which makes it the perfect item to build on a core Leshrac. Besides the immense HP and mana bonuses it provides, the cooldown reduction allows Leshrac to put out even more damage in fights, and the spell lifesteal allows him to maintain his own HP pool from that damage. Once Leshrac has built up enough survivability to ensure that he can keep dealing damage with his spells, purchasing an Octarine Core can make him almost unkillable.
 * is a very strong utility item in the hands of Leshrac. Besides providing him with additional magic resistance, the active can act as an initiation aid to get within range to cast a disable, and can be cast on allies as well to safeguard them against magic nukes.

 * is important to purchase regularly as support Leshrac in order to remove enemy map vision. As support Leshrac is a frail and easy target to kill, taking away the enemy's vision can aid in his survivability, and allow him to better position himself to cast his spells without as much enemy interference.
 * is a strong early purchase as a core Leshrac, particularly in the mid lane. It gives him good starting stats, particularly intelligence and some extra bonus damage to aid in last-hitting. The intelligence also increases the size of his mana pool to allow him to use his spells to harass his lane opponent and flash-farm the creep waves more often.
 * gives mid Leshrac HP and mana sustain, ensuring that he can continue to lane even after using all of his starting regen; in particular, the mana regen allows him to cast his nukes more profligately. Bottling runes also gives him an edge in fights and laning.
 * is a good utility item to purchase on a support Leshrac over a Bracer. It boosts his strength to give him more HP, and a small amount of mana regen to aid in casting.

The additional movement speed also helps in chasing with Edict and Pulse Nova.
