A highlight video of Phantom Assassin played by iceiceice

Item Builds: In the early game Ring of Aquila will help him to sustain his mana and to spam Daggers, while Ring of Health (which later will be upgraded to Battle Fury) will give him enough HP sustain to trade hits with Doom. In the mid game BKB is mandatory if he wants to fight with Luna. In the late game he buys Octarine, which is not a standard choice for PA at all. Keep in mind, however, that he took the talent for triple Dagger, so he probably wants to experiment and spam the spell as often as possible.

Early Game: PA doesn't need any items to fight early (you can just spam Daggers and when you see a good opportunity you commit with Blink). Iceiceice becomes very active right from the early game.

Mid & Late Game: Never relieving the pressure allows his team to win a lot of map control, which allows Ice to flash farm very efficiently with the BF and get ahead in resources (he out-farms the enemy Luna).
