Ahem, as most of you know, creeps spawn every minute. But no doubt you've noticed the anti-spawn-when-hero-is-around system. Most think you mustn't look at the spot for the creeps to spawn, but that's not correct. Study this:
(Note: It's not up to date, but it's still pretty accurate)
The blue boxes in every panel represent the zone in which you, or any unit for that matter,
must not be for the creeps to spawn. In other words
keep out of the boxes when waiting for creeps to respawn.
But that's not enough.
If the corpse of a unit is in a box, then the creeps won't respawn. That means it's no good if you managed to kill them off and run away before the minute ends, hoping for a new batch of creeps.
When jungling, if you want as many creeps as possible, don't attack them if the time is over 35 seconds. This is due to the fact that by the time you manage to kill them, about 10 seconds pass, reaching 45 seconds. "So what's wrong with that?", you might ask? Well, corpses persist. They remain on the ground for about 15 seconds before they are removed. So if you are confident that you can kill all the creeps in the creep camp BEFORE the clock hits 45, then please be my guest (then remember to go out of the box), otherwise do this next trick.
A small side note: it's easier with golem camps because they do not leave corpses. Also keep in mind that some skills manipulate corpses (only Visage and Weaver come to mind right now), so you can use their skills when jungling.
If you find that you reached the camp sometime after 35-40 seconds, then don't panic, there is a way. Do not attack the creeps yet. Wait till the clock reaches about 52-53 seconds, THEN hit them, but only ONCE, and run away as far as possible till the clock reaches 00. The creeps will follow you. If you did it right, by the time the creeps return to their camp there will be other creeps there for you to kill. This is because by luring the creeps out of the box, the creep camp remains empty and a trigger will run, which makes new creeps.
Please do use this trick from now on, cos it's really helpful and you might be hurting other people's farming.
