High Ground is a damage gear perk that boosts weapon damage against enemies below you. It rewards fighting from rooftops, cliffs and towers.
Shooting down at soldiers deals more damage. Climb a roof or tower and you hit harder.
Good for snipers and anyone who fights from height. Its value drops in flat, close fights.
Featherfall, also on Altaïr's gear, helps you drop from your perch safely.
