Dark Seer

Dark Seer is a support caster hero that employs his skills to fully disorient his enemies through vacuums and illusions, as well as support his allies. As a melee hero, his overall attack and natural movement speed doesn't improve over time, making any follow-up melee attacks very risky. He's also a very versatile hero; He can gank with Vacuum, push with Ion Shell, initiate with Wall of Replica, support with Surge, giving him a persistent role on a team.

Tips

 * With a Stout Shield and healing items, you can jungle from lvl1.
 * If laning, be sure to harass enemies with Ion Shell by placing it on their melee creeps (for melee heroes) or ranged creeps (for ranged heroes)
 * Be sure to take at least 1 early point of Surge, as it can help escaping ganks and chasing, as well as giving more mobility.
 * When chasing, just put on Ion Shield and run next to the enemy without attacking, and use Surge if you need to catch up.
 * Wall of Replica is usually skilled after you've maxed both Ion Shell and Vacuum, as early game illusions dont deal much damage and early lvls you wont have enough mana to use it along with your spells.
 * AoE spells, especially those that require positioning, greatly benefit from Vacuum, as you can place all of them together to ensure a hit.
 * Be sure that when you cast Wall of Replica you vacuum the enemies through it.
