Soulbind cannot bind targets to their invisible allies, but will continue to bind them if they turn invisible.

What type(s) of vision does Soulbind give over its secondary target?

The chain is fully stretched at 600 range, but can actually stretch up to 700 range (using forced movement or teleportation) until it breaks.

At what range is the Soulbind chain considered 'fully stretched'?

Ally-casted Force Staff used to be able to break the leash if the target had not moved after being bound

Most forced movement sources can break Soulbind's leash effect. Which of the following cannot?

A few ways to affect a Soulbind-ed target with a creep ability are through Doom's Devour, or Rubick stealing a Doom's Devour-ed ability

Soulbind does duplicate abilities cast by creeps (including Dominated ones).

Brewling abilities are hard-coded to not affect Soulbinded targets, and all other creep-heroes (Familiars, Golem, Astral Spirit) do not have unit-targeted abilities. I guess a double Storm Brewling's Cyclone would be a little strong...

Soulbind does duplicate abilities cast by creep-heroes.

Legion Commander Duels the first, then the second target. If the second target is a creep-hero, neither can be the winner of the Duel (although this used to be possible, +300 damage Spirit Bear!).

Which Soulbind target receives the bonus damage from Legion Commander's Duel if Legion Commander dies?

This actually used to be the case even if the channel was canceled, as if they couldn't possibly make those two heroes annoying enough. It still applies even if the debuff expires, however.

Pudge's Dismember and Bane's Fiend's Grip always channel for their full duration on its secondary Soulbind-ed target.

Axe still gains the speed bonus if the secondary target dies to Culling Blade, however. He also receives the extra permanent bonus armor from his innate if either target dies.

Which Soulbind-ed target's death determines whether Axe's Culling Blade resets its cooldown?

This used to be the secondary target, as is common with most Soulbind interactions.

Which Soulbind-ed target does Clinkz issue an attack order on after casting Tar Bomb?

If Death's Prophet casts Spirit Siphon on the secondary Soulbind target while already Siphon-ing the first prior to the Soulbind, it will be affected by two Siphons.

Death's Prophet can affect a target twice with Spirit Siphon through Soulbind, despite her not being able to cast the ability on units already affected by Spirit Siphon.

This doesn't apply to the Beams that are fired from Eclipse.

Soulbind duplicates the 2 Moon Glaives fired on Luna's Lucent Beam from her Level 20 Talent.

Charge of Darkness will charge to the secondary target if the charge is blocked by the primary target. This also applies to Huskar's Life Break. This doesn't apply for Spell Reflection, however.

Spirit Breaker's Charge of Darkness can only possibly hit its primary Soulbind-ed target. No effect happens to the secondary target.

Soulbind does not copy any attack modifiers.

Ogre Magi's Level 25 'Fireblast on Attack' Talent

Soulbind can duplicate the following auto-cast abilities:

Soul Release will still show its visual effect on the secondary target, but the debuff will not be applied to them. Ion Shell used to ignore Spell Reflection as well.

Which of the following unit-targeted abilities CANNOT be reflected by Soulbind?

A similar situation happens with Vengeful Spirit's Swap: Vengeful Spirit swaps with the primary target, the primary target swaps with the secondary, then the secondary target swaps with Vengeful Spirit.

After casting, the order of the answer choices: 1) Terrorblade, 2) primary target, 3) secondary target

Terrorblade casts Sunder on a Soulbind-ed target. What order do the health values resolve as after casting?

Repeated castings of Soulbind refresh its duration; casting on a third target will not link to either of the two prior targets until the debuff expires.

A unit be affected by more than one Soulbind at a time.

Duplicated Soulbind spells used to ignore Spell Reflection on the secondary target.

Duplicated abilities can still be reflected/blocked by the secondary Soulbind target through Spell Reflection/Block (e.g. Lotus Orb).

If the secondary target has more status resistance than the primary, the bind will expire early for them and the primary target will leash the next valid target.

Soulbind's duration is independently calculated on each target through their status resistance.

Our favorite artist Grimstroke's ultimate ability Soulbind has a huge amount of complex spell interactions in the already-complex game of Dota 2. How well do you know them
