AlchemistHERO GAME PLAN

What I want to do in the game

I accelerate my economy and use my item advantage before the enemies catch up in strength.

Synthesizing extra resources from each and every kill, Alchemist has no trouble gathering the tools needed to destroy his foes. Ambushing enemies with corrosive acid and a host of unstable chemicals, he battles to ensure his greedy escapades can remain uninterrupted.

01 / ROLE IN THE TEAM

A pick is not a plan yet.

My recommendation is a starting point. We choose another position together with the team and for its needs.

01

Carry · position 1

Initial recommendation

I need protected farm, my item window and damage on important targets.

02

Mid · position 2

Levels, lane control and joining the team at the right moment matter.

MY VIEW OF THE HERO

Pick for a purpose. Play with a plan.

When I pick

I pick this if I can accelerate my economy quickly and the team lets me turn early items into map control.

What I watch out for

A closed-off jungle, constant attacks and prolonged farming without objectives erase the advantage. The same inventory later is no longer as valuable.

What I do in combat

I choose the nearest objective after a key purchase in advance. I do not keep accumulating gold forever if the team is ready to use my current advantage.

What I check first

Fast farming is not a win by itself: I turn early items into objectives and map control.

02 / ITEMS FOR A PURPOSE

What I buy and why.

This is an editorial starting plan based on hero mechanics. It is not presented as a match I have already tested or a popularity ranking.

Carry · position 1

My starting plan

Here is my initial plan: I do my role's job first, then choose the items the team needs. I adapt the order and expensive purchases to the opponent.

  1. 01 / First stepPhase Boots

    Help maintain close contact and pass through groups of units.

  2. 02 / FoundationRadiance

    Speeds up farming and pressures nearby enemies with constant damage; an expensive investment that needs time to pay off.

  3. 03 / FoundationBlink Dagger

    Changes the entry angle and lets me reach a target quickly. Damage taken can prevent its use.

  4. 04 / Next choiceBlack King Bar

    Provides a window for my actions against eligible magical damage and disables. I check effects that pierce the protection.

  5. 05 / Next choiceAssault Cuirass

    Gives the team armor and attack speed, helping it apply physical pressure to heroes and objectives.

What I change for the situation 3 options
Manta Style ↗

Provides illusions for pressure and a separate dispel. This item cannot help you wait out or remove every disable.

Abyssal Blade ↗

Provides a targeted disable when slows and attacks are no longer enough.

Aghanim's Scepter ↗

Unlocks or upgrades Greevil's Greed. The exact effects are shown below in the abilities section.

I see the minute on the clock. And the situation too.

I do not assign one ‘correct’ minute to every purchase. I look at my gold, the next fight and the problem: am I missing mana, target access, control or protection? If an expensive slot will arrive too late, I get a useful answer earlier.

03 / HERO ABILITIES

Abilities. As in the game.

Original Valve icons and descriptions. Cooldowns and mana are shown by level from the data snapshot; talents and upgrades can change the values.

Ability

Acid Spray

Sprays high-pressure acid across a target area. Enemy units who step across the contaminated terrain take damage per second and have their armor reduced.

↻ 21 sec.Mana 120
Ability

Unstable Concoction

The hero begins shaking a vial of unstable chemicals that can be thrown at an enemy hero. On impact, the vial explodes, stunning and damaging all enemies in the blast radius.

↻ 17 sec.Mana 100
Details

Alchemist brews up an unstable concoction that he can throw at an enemy hero, to stun and deal damage in an area around the explosion. The longer the concoction brews, the more damage it deals and the longer the stun. Alchemist is faster while charging the concoction. After 5 seconds, the brew reaches its maximum damage and stun time. However, after 5.5 seconds, the concoction will explode on Alchemist himself if not thrown.

Ability

Corrosive Weaponry

The hero enhances his weapons and abilities with acid that reduces his victims’ movement speed and base damage. This effect stacks.

Details

Alchemist coats his weapons and empowers his spells with an acid that applies a stacking slow and base attack damage reduction to enemies hit. Attacks apply 2 stacks. Unstable Concoction applies 1 stack per second of brew time.

Ability

Chemical Rage

A special chemical mixture enrages the hero, reducing his base attack time and increasing his movement speed and health regeneration.

↻ 60 sec.Mana 50 / 75 / 100
Details

Alchemist causes his Ogre to enter a chemically induced rage, reducing base attack cooldown and increasing movement speed and health regeneration. DISPEL TYPE: Basic Dispel

Innates, upgrades and other forms2 abilities +

These abilities are not necessarily available at the same time. I check the condition beside the name: innate ability, another form or an Aghanim purchase.

Innate

Greevil's Greed

Generates extra gold from enemies and runes. Bonus gold from unit kills has two parts: a base bonus and an increasing bonus for each unit killed within 40 sec. of the previous one.

Full description and upgrades

Alchemist synthesizes additional gold from his enemies and bounty runes. With each kill, Alchemist earns base bonus gold and extra bonus gold. If Alchemist kills another unit which yields gold within the next 40 seconds, an additional instance of Extra Bonus Gold is added to the total. Additionally, causes bounty runes to yield more gold.

Aghanim’s Scepter

The hero can melt an Aghanim's Scepter to give an ally all its upgrades, while gaining +15 attack damage and +3 to the base and maximum gold from Greevil's Greed. The bonuses gained from melting multiple scepters stack.
