    Chapter 1: Magic resistance
    HERO

    All heroes have an innate magic resistance of 25%. This means, whenever someone cast a spell against your hero, your hero will not receive all the damage. 25% of the damage will be negated or subtracted.


    Example: Lion used a level 3 Finger of Death to your hero...

    Expected Damage = 850
    Reduced Damage = 25% of 850
    = 850 x 0.25
    = 212.5

    Real Damage = 850 - 212.5
    = 637.5 or 638


    This is the beautiful thing. You expect that the damage of level 3 Finger of Death is 850, but in reality your hero will only receive 638 damage.




    ITEM

    More good news. There are items that you can buy for your hero to further increase the spell resistance. These are:



    khadgars pipe of insight
    Adds 30% magic resistance
    Cost: 3653 Gold


    Hood of Defiance
    Adds 30% magic resistance
    Cost: 2050 Gold

    Planewalker's Cloak
    Adds 15% magic resistance
    Cost: 400 Gold

    Item Stacking Rule. Do these items stack? No, they do not stack. These three items follows the "latest acquired" stacking rule. It means, only the spell resistance of the latest acquired item will work. If for example you have Hood of Defiance in your inventory and then you pick a Planewalker's Cloak, the magic resistance of Planewalker's Cloak will override Hood of Defiance's.

    Hero and Item Combined. Now we have two sources of magic resistance. Sadly, these two will stack with diminishing return. Here is the formula:


    Total Magic Resistance = 1 - ((1 - A) x (1 - B))

    where: A = hero innate magic resistance
    B = item's magic resistance


    Example: Your hero (25%) has Khadgar's Pipe of Insight (30%)
    Total Magic Resistance = 1 - ((1 - 25%) x (1 - 30%))
    = 1 - ((1 - 0.25) x (1 - 0.30))
    = 1 - ((0.75) x (0.7))
    = 1 - 0.525
    = 0.475 or 0.48
    = 48%


    This is how to compute the total magic resistance. With this formula, we can identify what is the total magic resistance of a hero with any of the item above:



    Planewalker's
    Cloak (15%) Hood of
    Defiance (30%) Khadgar's Pipe
    of Insight (30%)
    Hero Innate Magic
    Resistance (25%) 36% 48% 48%




    SKILL

    Some heroes has their own skill that will also increase their spell resistance. These heroes and skills are:


    Viper
    Skill: Corrosive Skin
    Adds 5% / 10% / 15% / 20% magic resistance

    Magina
    Skill: Spell Shield
    Adds 10% / 20% / 30% / 40% magic resistance
    Azwraith
    Skill: Phantom Edge
    Adds 10% / 15% / 20% magic resistance
    Pudge
    Skill: Flesh Heap
    Adds 4% / 8% / 12% / 16% magic resistance


    These heroes are special. If you are using them, you will now have a third source of magic resistance. But the same with item, their skill will add to the toal magic resistance with diminishing return. Our formula will change a bit, here:


    Total Magic Resistance = 1 - ((1 - A) x (1 - B) x (1 - C))

    where: A = hero innate magic resistance
    B = item's magic resistance
    C = skill's magic resistance


    Example: Magina (25%) has a Hood of Defiance (30%) and a level 4 Spell Shield (40%)
    Total Magic Resistance = 1 - ((1 - 25%) x (1 - 30%) x (1 - 40%))
    = 1 - ((1 - 0.25) x (1 - 0.30) x (1 - 0.40))
    = 1 - ((0.75) x (0.7) x (0.6))
    = 1 - 0.315
    = 0.685 or 0.69
    = 69%


    So with this formula, we can identify what will be the total magic resistance of these heroes with their skill and item:


    Viper

    Chapter 2: Black king bar
    Spells that completely ignore BKB
    1. Any melee bash
    2. Any melee critical
    3. Naga Siren: Ensnare
    4. Tormented Soul: Diabolic Edict
    5. Gorgon: Purge
    6. Techies: Suicide
    7. Techies: Land mine
    8. Axe: Counter Helix
    9. Axe: Culling Blade
    10. Faceless Void: Chronosphere (Doesn't work if BKB is activated during your cast time)
    11. Nerubian Assasin: Vendetta
    12. Death Prophet: Exorcism
    13. Vengeful Spirit: Nether Swap
    14. Doombringer: Doom
    15. Juggernaut: Omnislash
    16. Tidehunter: Anchor smash
    17. Beastmaster: Wild Axes
    18. Silencer: Global Silence
    19. Bristleback: Quill Spray
    20. Lord of Olympia: Static field
    21. Earthshaker: Echo slam
    First wave of echo slam that deals the initial damage will go through
    22. Enigma: Midnight Pulse
    23. Tinker: March Of The Machines
    24. Slardar: Amplify damage
    25. SandKing: caustic finale
    26. Geomancer: Geostrike
    27. Geomancer: Earthbind
    28. Witch Doctor: Voodoo restoration
    29. Spiritbreaker: Greater bash
    30. Spiritbreaker: Netherstrike
    31. Pit Lord: Pit Of Malice(Note that you cannot cast BKB too when you are stopped by pit during that 3 seconds too)
    32. Storm Spirit: Grapple


    Spells that deal no damage, but still cause side effects on BKB users
    1. Bane Elemental: Fiend's Grip
    2. Necrolyte: Reaper's Scythe
    3. Butcher: Dismember
    4. Butcher: Meat Hook
    5. Antimage: Mana Void
    6. Terrorblade: Sunder
    7. Slardar: Amplify Damage

    If the target is immune to magic, then its HP will not change but terrorblade's will. If Terrorblade is immune to magic, then his HP will not change but the target's will. Sunder will only have no effect if BOTH terrorblade and the target unit is immune to magic.


    For all purposes of explanation, no. Sunder has remained largely unchanged since it was made. Although the spell can be cast on magic immune heroes, such heroes will remain unaffected by its effects. The BKB guide kakaboo linked to is unclear here; magic immunity of its caster per se will not affect whether or not Sunder has an effect on its target, and vice versa. I'll update it.

    To reiterate, Sunder is castable on magic immunes, but they will not, however, be affected by it. If a Soul Keeper somewhere were dying, at 3% hitpoints, and he Sundered a magic immune hero with full hitpoints, that Soul Keeper would be healed fully, while his target's hitpoints would remain unchanged. If the Soul Keeper were the only one magic immune in that encounter, he would not be healed. The target's hitpoints would be then lowered to 33/28/23%, depending on the level of Sunder.

    8. Spirit Bear: Entangle
    9. Enigma: Black Hole
    10. Mercurial: Spectral Dagger - No damage but slowed
    11. Sniper: Assasinate -No damage but will still stun and give vision to the target
    12. Poison Touch - Can be casted on BKBed hero but will have no effect. If BKB used after Poison Touch, hero will be immune to slow but not the damage.
    13. Weave - Can be casted on BKBed hero but will have no effect. If BKB is casted after weave, weave will still take effect.
    14. Warlock : Infernal - Immune to damage but not immune to stun
    15. Warlock : Fatal bonds - Immune if you were targeted directly, not immune if it was bounced to you
    16. Sacred Warrior: Inner Vitality: If BKB is casted after inner vitality, inner vitality buff will not be removed.
    17. Storm Spirit: Barrier: If BKB is casted after barrier, barrier buff will not be removed.
    18. Magnataur: Reverse Polarity
    19. Beastmaster: Primal Roar

    Items with effects that goes through BKB

    1. Dagon : You can cast dagon on an avatared hero but it will have no damage at all
    2. Maelstrom/Mjolnir (Chain lightning) : The animation will occur but it will deal no damage at all
    3. Corruption : Goes through it completely
    4. Maim : Goes through it completely
    5. Skadi's frost : Goes through it completely

    Special mentions
