I can pwn cosplay at max threads using no consumables with 320 PP. The book, ripro, and the implant are really all you need if your build and other .moars are solid. I could probably get by without the hacker book, but I was a fool when I was a noob, and sold it. When comparing hackers to trolls remember that the main hacker attacks you use cost 10, 7, 0, 3, 0, 5, and 3 PP (so average of 4 1/6 PP per attack). Wherease trolls just spam two 8 DB attacks. If they deal comparable damage, the hacker should need less PP than the troll needs DB.
