Here are all the useful chokepoint areas, showing which trees need to be cut to use them:







This last one doesn't work that reliably. The spot where it works is pretty small.

Starting items should either be stout+hatchet+tango (safer), or RoP+hatchet+tango (riskier but gets aquila slightly faster).

There isn't a fixed order that you should do camps in. Don't try to do the more damaging camps on low HP until 2+ levels in healing ward. Get the second point of healing ward at either level 3 or 4 depending on how it's going.

Don't take the small camp from your support. It's inefficient to farm and it deprives them of the ability to pull.

First major item should be Aquila, with the Wraith Band coming first (even if you started with RoP). Just put the components on the courier as you can afford them, and take them right after your mid gets their bottle off the courier.

Done correctly, at 15 minutes you should have Aquila + Phase + Bfury or equivalent.
