Dota – What happens when you pick up rune, when you already have one bottled

dota-2

I'm specifically refering to such situation:

Dota 2 Purge plays Bounty Hunter at (from 24:22 to 24:32)

He basically picks up Double Damage, waits a bit as he notices rune spawn time is near, then pickups Illusion. So my question is: Did the runes stacked in his bottle and he just activated Illusion to have Double Damage ready? Or perhaps bootle can store just one rune and when you pick up rune, while another one is already bootled, then it behaves like you have no bottle at all (ie: instantly activating a rune).

Best Answer

You can have only one Rune in the bottle at a time.

  1. If you pickup a second rune, it activates it as if you had normally picked it up
  2. If you activate your bottle rune then you can store the other one in it

What happens in the video is the scenario 1. The Bounty Hunter stores the Double Damage in the bottle then activates the illusion rune by picking it up. You can see the Double Damage still sitting in the bottle when he selects back his Hero.
