Dota 2 - Dark Seer Build Guide

BIO
Fast when he needs to be, and a cunning strategist, Ish'Kafel the Dark Seer requires no edged weapons to vanquish his enemies, relying instead on the strength of his powerful mind. His talent lies in his ability to maneuver the fight to his advantage. Hailing from a place he calls 'The Land behind the wall,' Dark Seer remains an outsider here-a warrior from a realm beyond the veil of this reality.

Once a great general among his people, and a valiant defender of the god-king Damathryx, Dark Seer's army was wiped out by a much larger force in the final days of the Great Boundaries War. Facing certain defeat, he made one last desperate act: he led the enemy forces into the maze between the walls. At the last moment, just before capture, he crossed over-then sealed the walls forever in an explosive release of dark energy. When the dust settled, he saw that he had saved his people but found himself blinking at the sun of a different world, with no way to return. Now he is committed to proving his worth as a military strategist, and vows to show that he's the greatest tactician this strange new world has ever seen.

Why maxed Ion Shell first?  This is your main DPS source, you will need this for farming, ganking and killing on early-mid game.

Why maxed Surge before Vacuum?  For early-mid game, a level 1 Vacuum is enough. And you should maxed Suege to always can escape with maximum movement speed if the enemy wants to gank you. And also Surge should be maxed to be always can cast it for chasing enemies.

STRATEGY
Early Game
Ion Shell is your main source of damage here. You can cast this for allied creep while you are far away from the creeps clashing area and keep getting gold because the damage from the shell is killing enemy creeps. That way is useful when you are doing an offlane solo Dark Seer because you need to be far away from the creep wave to avoid getting ganked and being killed. Or you can csat this to enemy creeps and the shell will do the work, it will damaging the nearest creeps and enemy hero and you will get golds eventually, and also keep harassing your enemy on your lane. Or cast this to your self and start harassing enemy by moving directly to him.

Mid Game
Mid game is the time for ganking. Everybody should start finding enemy hero and start getting as many kills as possible. Ion Shell still be the main source of damage for you here. You need to cast this for yourself and also for the melee hero in your team so if the clash begins you and your melee friend will come near the opponent and the Shell is damaging enemy by a lot.

Remember to cast Surge in 2 conditions
1. You or your allies needs to escape immediately from the enemy. With a maximum movement speed, it will be easier to escape.
2. Your team needs to chase the enemy

Late Game
Late game is the time for a big clash to happens. And you have some nice abilities to be cast on a big clash to make a big combo. Here is the example:
You have the Vacuum and one of your friend is Enigma:
If you have the Blink Dagger, you should use it first to jump into near enemy's wave
1. Cast the Vacuum so all enemies willl be dragged into 1 point in the ground
2. Enigma can immediately cast a powerful Blackhole that catch all enemies in the area
3. Cast the Wall of Replica into the middle of the teamfight so you get enemys replica that will help your team deal as many damage in the teamfight.
4. Your carries can easily damaging the Blackholed eneemies so your team can win the teamfight
That's the method on creating a big combo so your team can achieve a brightful victory.
