What actions does Legion Commander's “Duel” Abillity restrict?

Question

The Legion Commander's ultimate skill "Duel" disables spells and items and 'some' passive abilities during its duration.

IE: Supposedly one of these passives is critical strikes.

Can anyone break this skill down and explain in detail what exactly you can and cannot do while under its effects?

  Hex,bkb,eul,manta,dagon...

• Abilities (all) (you and target)

  Lightning bolt,wind walk,rupture...

• Passive abilities from items (some,mostly orb effects and attack modifiers) (you and target)

• Passive abilities (some,mostly orb effects and attack modifiers) (you and target)

  • Frostmourne, Abaddon

  • Bash, Void (and all other bash skills, except Greater bash - Barathrum)

  • Blur, Mortred (and all other evasion skill, except Psedu-evasion Backtrack - Darkterror)

  • Great Cleave, Sven (and all other Cleave skill, including Tidebringer - Kunkka)

  • Coup degrace, Mortred (and all other critical skills, no exceptions!)

If you ever see the animation of bashing or mana burn,or activated items they were activated duel started.

As you can see castable things are disabled since it is supossed to be "autoattack" duel without interferance and most orb effects and passive skills are disabled since some of them make targeted enemies impossible to defeat imagine duel with ursa or slark,if they had their passive skills it would be clear suicide.

Basically the duel casts "doom" on you and your target here is even larger list.
