Establish a lane workshop

0:00–14:00, or until the first tower falls or the lane can no longer be held safely

Build a repeatable lane zone around the wave and your escape route. Use turrets to make last-hit contests expensive, use rockets when the opponent gives you a predictable line, and keep grenade for a committed trade or gank response. If you need to recall or roam, crash first; if you are behind, prioritize safe CS and XP near your prepared ground rather than defending every plate. Transition when the first tower falls, the lane becomes unsafe, or an objective timer requires your zone elsewhere: reset, move with the wave, and rebuild on the next useful area.

Lane

Choose the wave state before placing turrets

If the wave is moving toward your tower and your turret cluster can hold the space safely, last-hit and preserve mana instead of forcing a push. If you need to recall or move to a river play, crash the wave first; turrets create pressure, but they do not replace a completed wave reset.

With Heimerdinger

• If Heimer has turrets near the lane or objective entrance, fight around that zone rather than dragging him into open ground. Frontliners should make the enemy choose whether to enter the turrets, while damage dealers wait for the grenade threat to constrain movement.
• If Heimer is pushing a side wave and his team is near the next timer, cover the approach without demanding that he join a random fight immediately. His pressure is useful when your group threatens a conversion as soon as an enemy answers him.
• If Heimer holds grenade for peel, give him time to react to the engage instead of forcing him to spend it on your initiation. When his upgraded spell is available, identify the one structure, choke, or enemy entry that the team can realistically pressure during its window.
