I had in mind p7 focusing only Vizier seal with maybe adding Infector seal though that's questionable. Overall not touching De Seis nor doing this seal killing thing. Hammer can try the seal tactics however sorc could do only Vizier plus few ghost packs.
Comparison is one ghost killed on p7 is roughly as killing 2.7 cows on p5. Good characters can aim to kill 2.5 cows per second average which would mean sorc should kill ~1 ghosts per second to be comparable. Each ghost counts as 3.56 other creep types in sanctuary. Whether or not is this possible should be tested. Hammer can do seal trick.
