I respecced my hammerdin into a Fohdin. He's not stronger, but I'm getting along better with FoH than with BH. I also think that he's more versatile. While BH doesn't affect any magic immune monsters (like Baal wave 2), only unbreakable lightning immune animals are immune to FoH altogether.
The key is to attack with FoH in a manner that as many holy bolts pass through as many opponents as possible. Apart from holy bolt damaging demons as well now (including those from FoH), they also pierce. His only nemesis are lightning immune animals that cannot be broken with maxed conviction. Also, you can leave the merc a bit behind by charging to everywhere, so he's not being killed that easily.
He also brings me luck, I've found a perfect Ravenfrost half an hour ago! I started with /p3 Pits, but /p3 CS is fine as well and it's more fun. I'm not sure what's more profitable, however, level 2 of the Pits or Diablo.
Regarding CS, de Seis seems to appear closer to the seal than before now. A few moments ago, he appeared right next to the seal, catching me totally unprepared and being amped, so she died, but that might have happened because I left a boss behind who might have been at the spot where de Seis ought to appear.
As soon as I get my hands on a Jah rune, I will probably make a Faith bow, let's see how much better physical bowazons are then, with strafe synergies. I guess she would be as strong with Skullder's as she was before while with Fortitude, i.e. good enough for CS and Throne Room, but with more MF.
I also have to respec my blizzard sorc, as she can cast frozen orb in parallel now (spells with a cast delay don't impose a delay on spells anymore that have a delay as well), but I'm lacking resources for effective Baal runs and I'm reluctant to spend a respec reward, respectively go to normal or nightmare with her and thus give up my pretty good map for Mephisto, Andariel, Tunnels and Lower Kurast.
Further things to try: Nova sorc, hydra sorc, fire druid, blade fury and trap assassin etc., but that has to wait until I have more resources.
