What does Hex do?

What does hex do?

Reduces a hero' speed to 100. However, speed bonuses from aura, skills, items etc. all apply.
Example: If a Centaur with Boots of Speed is hexxed, he has 150 movespeed.
If a Nerubian Weaver that uses Shukuchi is hexxed, it has 522 movespeed (since Shukuchi by default increases its movespeed to 522)
If a Spirit Breaker with Boots of Travel and Empowering Haste is hexxed, it has 205 movespeed.

Cancels channeling spells;
Instantly destroys an illusion;
Pacifies (causes an unit to be unable to attack) an unit;
Silence an unit, including item spell (if a hero turned on a spell, he can't turn it off during the hexxed period);
Stops SOME passive abilities such as:
Permanent Invisibility;
Evasion from Butterfly, Radiance;
Phantom Assassin's Blur
What does hex not do?

Does NOT remove any buffs.
Does NOT affect aura.
Does NOT affect armor or armor type.
Does NOT affect magic resistance.
Does NOT affect SOME passive abilites such as:
Backtrack (Faceless Void);
Counter Helix (Axe);
Craggy Exterior (Tiny);
Return (Centaur and Blade Mail);
Spike Carapace (Nerubian Assassin)
Other notes about hex:

Hex with Guinsoo's Scythe of Vyse always turns a unit to a sheep, while hex from Rhasta and Lion turn units to a random animal.
