Shop · Valve snapshot / Give an ally another window to act

I would buy BKB when I need a more reliable window for my own attacks and abilities in a fight. I activate it before the dangerous effects start chaining.

BKB: a window to act

0:14
Explanation text

OOPS DOTA. BKB gives you a window to do your job in a fight. It doesn’t cancel everything the enemy can do. Check the item description and the enemy’s disables in the current patch. Plan which actions you’ll fit into that window. Pressing the golden button and standing still isn’t much of a plan.

How I decide

«I press BKB for my own action while it is still possible.»

Ruslan UkrainskyiSpeaking through Rodya
01 Situation
Enemy disables constantly interrupt my attacks or an important ability.
02 My decision
I choose a moment before a dangerous chain of effects and use the protected window to pursue my preselected objective.
03 What I avoid
Wait for the last sliver of health when I can no longer activate Avatar.
02 / MY GUIDELINE

When I would buy it

Before the decisive fight, if the hero cannot use the damage they have already built without protection. On a support, it depends on the specific task and income.

Valve notes

  • Purchasing another Black King Bar will not reset its immunity duration.
  • Avatar duration is not affected by increases to buff duration.

Game effects and recipes are a snapshot of official data. My guidelines are choices for a task, not a promise of the same build every match. Values for several stages, where present, are separated by ‘/’.
