The International 2014 Battle Point Booster

This booster comes with The International Compendium 2014. Unlike other boosters, its Battle Point bonus increases as the compendium is levelled up. Currently, this item is "hidden" and not visible in the Armory, but has been automatically applied to all players who own the compendium.

It lasts until July 28, 2014.

Levels
The compendium can be levelled infinitely. After level 100, the booster will gain an extra 100% bonus every 100 levels.
