This is based off of _B O G I_'s build.

You should get phase boots by level 6 or 7.

If you are against a trilane and sentries just take exp and don`t die. The most imporant thing with brood is to not die early game vs sentries. At lvl 6 you can start killing their solo support 1v3 or their carry if their supports roam or pull. This is a good build if you are going against a lineup that heavily counters broodmother, such as axe or legion. This build ignores the spiders to make yourself strong in 1v1.
