Does BKB Block Blade Mail? Unraveling the Dota 2 Interaction
The question of whether a Black King Bar (BKB) blocks the damage reflected by a Blade Mail is a common point of confusion among Dota 2 players. The simple answer is: Yes, a BKB will block the magical damage reflected by Blade Mail. When a hero activates BKB, they gain spell immunity, making them invulnerable to most magical damage and disables. Since Blade Mail reflects damage as magical damage, BKB effectively negates it. This interaction is crucial for understanding how to survive and counter specific heroes and situations.
Understanding the Core Mechanics
Before diving deeper, let’s clarify the individual mechanics of both items:
- Blade Mail: When activated, Blade Mail reflects a percentage of damage taken back to the attacker as magical damage (100% before patch 7.33, now 80% of pre-reduction damage, with a 35% damage reduction threshold). This reflected damage is calculated before any damage reductions on the attacker’s end.
- Black King Bar (BKB): Grants the user spell immunity, which makes them immune to most spells and magical damage. While active, the BKB user can still take physical and pure damage. BKB has diminishing durations with each successive use in a game.
The interaction stems from the fact that Blade Mail returns magical damage to the attacker. Since BKB grants spell immunity and blocks most forms of magic damage, it directly counters the reflected damage. This leads to strategic decisions during gameplay, as heroes with Blade Mail will want to bait out BKB activations before committing to a fight.
Strategic Implications in Dota 2
Understanding this interaction is essential for several reasons:
- Choosing Item Builds: Knowing that BKB counters Blade Mail can influence your item choices. If the enemy team relies heavily on Blade Mail to deal damage, prioritizing a BKB is crucial.
- Team Fight Dynamics: In team fights, coordinating BKB timings with your team can minimize the impact of Blade Mail users. Baiting out enemy BKBs before initiating on heroes who rely on reflected damage is a valid strategy.
- Countering Specific Heroes: Certain heroes, like Axe or Legion Commander, are heavily reliant on Blade Mail to maximize their effectiveness. BKB allows you to engage these heroes with reduced risk.
Blade Mail’s Nuances
It’s important to note some specific situations where the BKB and Blade Mail interaction becomes more nuanced:
- Damage Threshold: Blade Mail features a damage threshold: damage instances below a certain value (35) are not reflected.
- Damage Types: While BKB blocks reflected magical damage, it does not block reflected physical or pure damage if Blade Mail were to ever reflect those damage types. As a result, Blade Mail’s damage type will always be the same as the type that it received.
- Edge Cases: There are some edge cases where certain spells interact uniquely with Blade Mail and BKB, often requiring testing or specific knowledge to understand fully. These are normally bugs that Valve addresses quickly.
Frequently Asked Questions (FAQs) About BKB and Blade Mail
Here are some frequently asked questions about the interaction between BKB and Blade Mail, along with other related inquiries, to provide a comprehensive understanding:
1. If I attack someone with BKB activated while having Blade Mail, will I take damage?
No. Because BKB grants spell immunity and Blade Mail reflects magical damage, the damage you would normally take from Blade Mail is negated.
2. Does Blade Mail reflect pure damage through BKB?
No. Currently, Blade Mail reflects the damage type it receives as the damage type it deals. Since reflected Blade Mail damage is magical, BKB completely blocks it.
3. Does activating BKB remove the Blade Mail debuff?
There is no debuff. Blade Mail is an active ability that reflects damage received. BKB simply negates the reflected damage, not removing a debuff.
4. Does Blade Mail work against Death Ward?
No, Blade Mail will not reflect any Death Ward damage back onto Witch Doctor, as Death Ward is considered a separate unit.
5. Can Blade Mail reflect Blade Mail damage?
No, Blade Mail does not reflect damage taken from other Blade Mails. It prevents infinite loops of damage reflection.
6. If two heroes have Blade Mail activated and attack each other, what happens?
They will both take the initial damage from the attack, as that damage is determined before reductions, and then the magical damage reflection is calculated.
7. Does Blade Mail stack?
No. Multiple instances of Damage Return from Blade Mails do not stack. The game only considers one Blade Mail instance at a time.
8. Can Nullifier remove BKB?
Yes, the Nullifier item will remove the spell immunity granted by BKB.
9. Does BKB block physical damage?
BKB does not directly block physical damage. However, it provides spell immunity, which blocks spells that deal physical damage if those spells do not pierce spell immunity.
10. Can BKB dispel Silence?
Yes, activating BKB will dispel silence if the silence was applied before the BKB activation.
11. Does BKB block magical damage?
Yes. The primary purpose of BKB is to block magical damage by granting spell immunity.
12. How does Dark Willow interact with Blade Mail and BKB?
Blade Mail reflects Dark Willow’s high burst damage back to her, potentially killing her quickly. BKB completely negates most of Dark Willow’s spells.
13. Does Anti-Mage counter Medusa?
Yes, Anti-Mage is considered a counter to Medusa due to his mana-burning abilities and high mobility.
14. Does Blade Mail go through Shadow Realm?
Only physical damage from Shadow Realm goes through BKB and the effects are reflected.
15. Does Eternal Shroud Stack?
Unlike all the other magic resistance items, only eternal shroud cannot stack magic resistance with itself.
The Future of Dota 2 Item Interactions

Staying updated on the latest patch notes and community discussions is essential for any serious Dota 2 player. Websites and forums often host discussions about new strategies, item builds, and hero counters, fostering a vibrant community focused on understanding the game’s complex mechanics. Exploring resources like the Games Learning Society at GamesLearningSociety.org, might further enrich your understanding of the strategic and tactical elements within the gaming world.
In conclusion, understanding the interaction between BKB and Blade Mail is just one aspect of mastering Dota 2. By delving into the intricacies of item interactions, players can make more informed decisions, improve their gameplay, and achieve greater success on the battlefield.
