* Bane's Enfeeble makes Ursa more susceptible to disables as it reduces Status Resistance.
* Bane can use Nightmare and Fiend's Grip to lock down Ursa early game and in team fights, forcing Ursa to buy a Black King Bar and making him very vulnerable to being kited once his Black King Bar is down to 5 seconds.
* Overall, Bane's potent disables force Ursa to build more defensive items and play more defensively in general.

* Summon Familiars can scout Techies as they are placing mines. They even trigger Stasis Trap.

* Nightmare and Fiend's Grip can ground Phantom Assassin, who normally blinks around with Phantom Strike, and stop her from outputting damage.

* Nightmare and Fiend's Grip help to control/disable Troll Warlord in team-fights.

* Familiars deal many instances of damage quickly, minimizing the effectiveness of Spiked Carapace. They are, however, relatively fragile and can be killed quickly with Nyx Assassin's high burst damage, especially from Vendetta.
* Gravekeeper's Cloak and tanky item builds make him hard to kill with burst damage.
* Visage's long range on Soul Assumption and Grave Chill make him hard to escape from, and Soul Assumption's low cooldown outmatches Spiked Carapace.

Additional:
* Due to their high attack speed, Visage's Summon Familiars will destroy Mass Serpent Ward quickly, granting Visage massive amount of gold.

* Fiend's Grip and Nightmare are very useful to lock down Void Spirit.

* Soul Assumption charges can easily be stacked up from Freezing Field, allowing Visage to nuke enemies multiple times throughout the fight.
* {U:Familiar}'s Stone Form can also be used to interrupt Freezing Field, even while Crystal Maiden is under the effects of Glimmer Cape. Crystal Maiden must purchase a Black King Bar, which is far more costly.

* Fiend's Grip and an Aghanim's Scepter upgraded Brain Sap pierces spell immunity, rendering Blade Fury nearly useless.

* Fiend's Grip's very long disable prevents Anti-Mage from Blinking away or using Manta Style. It also pierces spell immunity.

* Enfeeble lowers Anti-Mage's status resistance and magic resistance, making him more vulnerable to disables and magic damage that normally would not affect him much.
