#vision

The Gem of True Sight — a carried item that makes nearby invisible enemies pop into view, permanently.

The ward that gives you eyes on a chunk of the map.

Map bushes that hide you from sight, prime ambush spots.

A placed item that gives you vision of part of the map.

The ward that gives True Sight — reveals invis units and enemy wards.

Hunting down and smashing the enemy's wards to blind them.
