Converting a kill
Turning a kill into a tower, a dragon or camps.

« Enemy down? A door swings open for a few seconds. Count who's still alive, then walk through: the tower right there, the dragon, their camps. »
- The kill
Your bot lane kills both of theirs. They wait in their base for several seconds: that's your window.
- Count who's left
Three of them are alive: top, jungle, mid, all far from bot and the dragon. Nobody can stop you.
- Cash in
Your wave and your duo take their tower; your jungler and mid take the dragon. All before they're back.
- The classic mistake
Same kills, then you walk back to base and everyone farms. They come back to an intact map: the kill bought nothing.
When to do it
- You just got a kill: they're out for several seconds, and longer as the game goes on.
- Your wave is with you: plates or the tower are right there, with nobody to defend them.
- An objective is nearby: the dragon, or their camps, with one fewer of them to contest.
How to keep it
- Count who's alive, and where: if the others are far, you have time; if they're close, careful.
- Take what's closest first: the tower in front of you before an objective across the map.
- Nothing doable? Back: you spend your gold while they're dead, and lose nothing in lane.
The tip for your rank
After a kill, ask one question: what can I hit right now? Often, it's the tower in front of you.
Look at the map before you choose: count who's alive and where they are, then go for the tower, the dragon or their camps.
Call the play before the kill lands: your team is already heading for the objective when they die, and none of the window is lost.
