Why stack and pull
Stacking and pulling are two basic ways to get more resources off the map without risking a fight. A stack saves up extra neutrals for later: one camp becomes a double, triple or bigger, and all that gold and experience waits to be cleared. A pull drags your lane creeps into the jungle and controls where the lane stands right now. Both are timing-driven — like river runes, a stack is caught on the minute mark and usually grabbed on the way to a rune. Neither shows up as a kill on the scoreboard — but together they build an economic lead.
A stack creates resources for the future; a pull controls the lane in the present. A team that stacks and pulls reaches mid-game with noticeably more gold and experience for the same number of kills.
What creep stacking is
Every neutral camp is checked for a spawn at the start of each game minute. If the creeps are still standing in their spawn area at that moment, no new set appears. But if you pull them out of the area so it's empty at the start of the minute, a fresh set spawns next to the old creeps — that's a stack.
Two stacks make a double camp, three a triple, and so on. The bigger the stack, the more gold and experience it gives in a single clear — and a strong core can clear a big stack very quickly while also collecting its neutral items. So a stack is essentially delayed farm: you spend a few seconds now so someone can collect a tripled camp later.
Clearing a triple camp in one go is faster and safer than visiting a single camp three times. A stack concentrates resources in time — especially valuable for a carry, where every sped-up item counts.
How to stack properly
Exact spots and timings shift a little from map to map, but the technique is always the same:
- Approach the camp near the end of the minute. Creeps are usually aggroed about 4–7 seconds before the new minute starts — the exact time depends on how far the camp is from where you pull them.
- Pull the creeps out of the spawn area. Attack one creep and step away so the whole camp follows you and fully leaves the spawn area by the start of the minute.
- Let the creeps walk back. Once the new set has spawned, release the old ones — they return to the camp, and now there are two sets there.
- Stack on the way. Don't detour across the map: stack camps that are already on your path between tasks — a rune, a ward, a rotation. With practice you can grab several stacks in one trip.
Supports usually stack for the carry's lane, but a mid or offlaner with a free minute can stack for themselves. Who covers what on the map is in the roles and positions in Dota 2 guide.
Spawn box and camp blocking
Stacking and camp blocking rest on the same rule: a camp does not spawn creeps while any selectable unit stands inside its spawn box — even an invulnerable or hidden one. Everything else follows from that:
- Hold ALT to see the box. Hold ALT and the spawn-box borders light up right on the map (if the option is enabled). It is the fastest way to tell whether you pulled the creeps far enough.
- Blocking is the same trick in reverse. A ward planted inside the spawn box stops the camp from appearing at all: the enemy loses the farm and the option to pull. It works in your own jungle and in theirs.
- Not everything blocks. Couriers, Beastmaster hawks, Elder Titan astral spirits, Broodmother webs, Techies mines, Templar Assassin traps and Clinkz skeleton archers do not block a camp. Spells never block a camp — only units do.
- Roshan and the Tormentors cannot be blocked. They spawn regardless of what stands next to them.
The flip side of the rule is familiar to every support: when a stack quietly fails, the culprit is usually your own ward left inside the spawn box.
Pulling: what and why
A pull is when you draw your lane creep wave into a neutral camp so they fight. It's usually the same support who runs smoke ganks, and you pull for three things at once:
- Lane control. A pull drags the wave back toward your tower — the lane becomes safer for the carry and harder to gank.
- Denying the enemy. If lane creeps die in the jungle, the enemy offlaner gets less gold and experience from them.
- Support farm. You take both the neutrals and part of the lane wave — a tidy way to top up resources without stealing the carry's farm.
There's a simple pull (the wave goes into a single camp) and a pull into a stack (the wave enters a pre-stacked camp and dies en masse). When to pull depends on where the lane is heading: if the wave is pushing toward the enemy and you want it back, it's pull time. More on lane equilibrium in the denying and lane control guide.
Common mistakes
These slip-ups show up at every rank — and fixing them adds free gold out of nowhere:
- Stacking too late. Aggro the creeps too late and they don't clear the area by the minute mark, so the stack fails. Better to start a touch early and wait.
- Nobody collects the stack. A stack that's built but never cleared is wasted. Coordinate so a core picks it up before it "goes stale".
- Pulling into a push. If the lane already sits at your tower, pulling just hands the wave to the enemy and takes farm from your own side. Pull when the wave is heading toward the enemy, not away.
- Stacking at the map's expense. Running across half the map for one stack and dying to a gank costs more than the stack is worth. Stack on the way and with vision — see the warding in Dota 2 guide.
