 * is very dangerous to Dark Seer, because even if he tries to escape with Surge he will lose all of his mana and get stunned.
 * makes landing the Vacuum and Wall of Replica combo harder.


 * Oracle can remove and/or Surge by casting . This makes any gank attempt on Dark Seer in the laning phase very likely to succeed.

 * A Sniper who is somewhat competent at positioning will never be hit by any of Dark Seer's spells thanks to.

Others

 * Vacuum can take a single hurt meepo for a sucess and fast kill him by Dark Seer teammates before blink with or trying escape with boots of travel to base.
 * Also help teammates landing AoE skills to overwhelm meepos.


 * Venomancer is a low health hero and low range distance attack hero easily to harass putting Ion Shell in a distance creep enemy in early game.
 * Venomancer depends entirely on all his slows poison skills to keep distance or chasing enemy heroes, but Surge ignores slows, so is nearly impossible hunt or run away of Dark Seer or his surged teammates.

 * Ion Shell on Riki allows him to do a lot of damage whilst staying invisible.


 * Dark Seer's Ion Shell along with gives both Luna and Dark Seer big advantage to farm, while Surge gives Luna bonus movement speed to escape pursuits or to chase fleeing heroes, Vacuum is also a good setup for.


 * Since 's can stun enemies in a small area, Dark Seer can use his Vacuum to pull enemies into the spot allowing  to hit all enemies at the very spot.
 * Sven can kill heroes that got pulled together by Vacuum very quickly due to his
