If you are solo at a Fel champ you will get 6 powerscrolls, an average of probably 2 pinks, I don't think it matters the method you use as regards pets and summons etc.
Ive been soloing Fel ones for months, 1 or 2 daily, I began using a mage-tamer but really a tamer is only viable for the rat spawn(and even then you are looking at 1 hour 20 mins+), which means you try your luck at lost lands spawns or you go to despise, the problem is that despise is number one PK destination and if you are working solo that's not good.
These days I use a chiv thrower, I believe this to be the optimum champ spawn solo char but anyone correct me if they know better, can do any of the 5 possible random spawns, 40 mins for rat spawn to 1 hour 10 mins roughly for unholy, the others usually an hour or less.
