Vision before an objective
Light the pit a minute early, and blind them.

« Walk into a dark pit and you're the experiment, not the scientist. Light it a minute early, clear their wards, and let them arrive blind. »
- A minute before
The dragon spawns in a minute. Your lanes are pushed: your team moves to the pit ahead of theirs.
- Light the pit and its ways in
A ward on each way in from their side, and a control ward on yours. The whole area around the pit is lit.
- Clear their wards
Your support's Oracle Lens finds their ward, and you destroy it. Now they're blind around the pit.
- You see them coming
The spawn: you're in place. They walk in through your wards, and you see them before they see you.
- The classic mistake
A few seconds before the spawn, no vision: you walk to the pit in the dark. All five of them are there.
When to do it
- About a minute before the dragon or the Baron: that's when the vision is set, not at the spawn.
- Your lanes are pushed: you can leave them first and reach the pit before their team.
- They're already around the pit: without vision, don't go in to find out. Look first.
How to keep it
- Ward the pit and its ways in: the entrances from their jungle, the river, your side.
- Clear their wards with the Oracle Lens, and put a control ward on your side of the pit.
- Get there first, together: pushed lanes let your team move before theirs.
The tip for your rank
Simple reflex: when the dragon is about to spawn, put a ward near its pit on your way there. Never walk to it blind.
Start a minute early: wards on the ways in, their wards cleared, a control ward on your side. Then the fight happens where you can see.
Push the lanes first, then set up together: the team that owns the vision around the pit decides when and where the fight starts.
