|Hero|| Tychus, Swann, Tassadar, |
|Description||You don't concern yourself with Zerglings. You specialized yourself in hunting for the big targets. Auto-attacks and abilities deal bonus damage vs massive units and killing massive units grants you additional experience points.|
|Effects|| damage vs massive|
damage vs massive while fully charged (Tassadar)
critical hit bonus damage vs massive (Nova)
grenade/ missile battery/ empower/ snipe/ corona damage vs massive
bonus xp from massive kills
This mastery increases your effectiveness versus massive units and increases your rewards for killing them. In its current state, BGH is not worth it for any heroes in the early game, as there's a lot of other better masteries. The only time where its really worth taking, is in the late game when you've run out of actually good masteries and just want some damage versus final big ultralisk.
This mastery increases your auto attack damage versus Massive units, your Frag Grenade damage, and gives you 15% more Experience for Massive units. It can be taken in the mid/late game, as its main purpose is to increase damage towards Ultralisks and other massive units. However, if you pick BGH early, you will get the most benefit from the experience bonus.
