Tower dive:

A tower dive is an aggressive play where a hero enters the enemy tower’s attack range to chase or kill an opponent, often while the enemy is still near the tower. It is risky because tower shots deal heavy damage, so dives usually rely on strong spells, extra heroes, or a clear health advantage.

In Dota 2, tower dives are used to secure kills, punish low-health enemies, or force lane pressure, but poor dives often lead to trading one kill for the diver’s death.
