What is Tower?
A tower is a defensive structure on the lanes that attacks enemies and protects heroes. Destroying enemy towers is a key part of strategic gameplay. Each of the three lanes has 3 towers (tiers 1, 2, and 3), with increasing strength: the higher the tier, the more damage, health, and armor the tower has. In addition, each team has 2 tier 4 towers located near the Ancient. There are 22 towers in total on the map.
Each tower has Glyph of Fortification — an ability that temporarily makes it (and other structures) invulnerable. When a tier 1 tower is destroyed on any lane, the team's glyph cooldown is refreshed, allowing them to use it again for defense.
After destroying an outer tier 2 tower on a side lane, the team gains access to capture the nearby Outpost near the Secret Shop, providing additional map control and a teleportation point.
