Dark SeerHERO GAME PLAN

What I want to do in the game

I speed up an allied initiator, move enemies with Vacuum and strengthen the fight with auras.

Versatile and strategic, Dark Seer excels at manipulating the positions of his enemies. Vacuuming foes into the attacks of his allies, he can turn enemy strength against itself by pulling foes through his replicating wall.

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.

03

Offlane · position 3

Initial recommendation

My resource is the team's space: I hold the lane and build for initiation or team protection.

MY VIEW OF THE HERO

Pick for a purpose. Play with a plan.

When I pick

This suits a team combo with Vacuum and helping a hero who needs a quick entry through Surge.

What I watch out for

Spread-out opponents and no allied follow-up reduce the value of an impressive Vacuum. Strong single-target control can stop the sped-up hero.

What I do in combat

I first see who is ready to damage the gathered group. I give Surge for a specific entry or exit route, not simply whenever it is off cooldown.

What I check first

Vacuum is more valuable with allied damage; I check whether follow-up is ready before jumping in.

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.

Offlane · position 3

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 stepArcane Boots

    Provide mana for laning and regular ability use.

  2. 02 / FoundationGuardian Greaves

    Combine mana and health sustain for the team; useful in prolonged fights together.

  3. 03 / FoundationBlink Dagger

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

  4. 04 / Next choicePipe of Insight

    Provides team protection against substantial magical damage.

  5. 05 / Next choiceShiva's Guard

    Adds armor and pressure in an area, helping limit the enemy’s health restoration.

What I change for the situation 3 options
Crimson Guard ↗

Protects the team against suitable sources of frequent physical damage, especially many small attacks.

Lotus Orb ↗

Lets me remove an eligible negative effect and complicates the opponent's targeted focus.

Refresher Orb ↗

Lets you repeat your main power window. Before buying, I consider whether I will have enough mana for both casts.

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.

Details and upgrades

Aghanim’s Shard

Units affected by this ability leave a trail with a radius of 150 that lasts 7 sec., slows enemies by 35% and deals 40 damage per second at intervals of 0.5 sec. The trail is not created when alternate cast is enabled.

Ability

Wall of Replica

Creates a wall of refracted light that slows and damages enemy heroes passing through it and creates copies of them controlled by the caster.

↻ 100 sec.Mana 125 / 250 / 375
Details

Raises a wall of warping light that slows, damages, and creates replicas of any enemy hero who crosses it. Enemy replicas serve at the Dark Seer's will. Replicas last until they are destroyed, or until the wall's duration ends.

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.

From Aghanim’s Scepter

Normal Punch

The next attack against an enemy hero cannot miss, creates a Wall of Replica copy of them, deals bonus damage, and stuns and knocks them back.

Full description

The next attack against an enemy hero cannot miss. It creates a copy from Wall of Replica, deals bonus damage, stuns and knocks the target back. The effect scales with the distance the ability's owner travelled in the 3 seconds before the attack, reaching maximum power at 1100 distance.

Innate

Quick Wit

Each point of Intelligence increases the hero’s attack speed by 1.

Full description

Dark Seer gains 1 Attack Speed from each point of Intelligence. When Dark Seer levels up, he restores a percentage of his max health and mana.
