Death Prophet plays like a mid game carry, not a traditional mid, so her whole plan is taking towers before 35 minutes.

Combine Crypt Swarm wave clear with Spirit Siphon sustain for a near unstoppable push timing between 15 and 25 minutes.

A well placed Silence in a chaotic teamfight hits 3 to 4 heroes and shuts down enemy combos.

Diving towers and fighting outnumbered works for her, since Spirit Siphon heals everything back afterward.

Max Crypt Swarm first for wave clear and harass, the standard mid build.

With Boots of Travel and Exorcism she can split push one lane, teleport to a fight, then push another objective.
