DoTA don't have a perfect build. DP can play assist or killer.
Assist is easier tho. Basically, you need to spam carrion swarm at
the start to farm and harass. Get many clarity potions, a few
ancient saps and ore gaunlet. Your next fountain trip should be
after you use your ultimate when you dun have mana and hp pots
left. Den make bracer and buy boots. For assist, get eul, vise,
manta den radiance. For killer, get 1 more bracer, dagon, linken,
skadi...
I never see clan match people choose their DP to be killer tho..
