Re: Help on Phantom Assasin.
I like Phase Aquila HotD BKB -> Basher
If you are getting babysit, then early BF/Midas is quite devastating.
Skill build wise, you max Dagger first. Get 1 point in Blur, then max Blink Strike next.
Alternatively, there is a Phase Vanguard Basher build.
I play all heroes solo mid. Sometimes if I'm against a heavy nuke team, I would go for Janggo, before building towards BKB. Cloak might be considered then. Stick is situational, almost never a need to upgrade to Wand.
Remember that you shouldn't play as a hard carry. You have quite good DPS potential early on with just Phase and Ulti, so you should abuse it and snowball. Only thing I hated about PA when I solo mid Pub is if there are too many nukers like Tinker. Forces me to rice a BKB first.
MKB is a good extension. Manta is decent, SnY if you need some HP too. I like Yasha alot on her, but I sort of dislike either extensions for PA :\
