You should skill inkswell over phantoms embrace if you have a core or a team that can go in regularly.
Item build varies from game to game but if you are doing well, having an early orchid helps with mana problems as well as the instant silence for some certain heros that can escape phantoms embrace. If you have good timing it is really good against anti mage and storm spirit and puck. Orchid into phantom and ink swell your core.

If you don't need orchid, first item aghs after boots and wand is the best route.


If you don't have any team mates to synergize with your ult, you might consider a spirit vessel as early item instead.
