I can do it really easily with a barbarian, and slightly slower with a necro using bone spirit, but how do you kill, them with the other chars? :

well if your using a pally blessed hammer or vengance, zon if you dont have light fury ur shit out fo luck,assin phenix strike.

Mostly, you just want a lot of Elemental damage, and Magic damage works too. Just something else that doesn't do physical.

Ok guyz, as previously pointed out, elemental or magic damage is the key to killing phyiscaly immune characters. all D2 characters have the ablility to have some form of elemental damage, DUH. Below, is the best skills that i have found to take care of those annoying bastards.

Barb- Mainly use a magic damage sword, concentrate also works if your a 2
handed fighter, if you have duel 1 handers use frenzy

Sorc- Duh i hope you can figure this out.

Pally- Blessed Hammer or FOH works very well, Vengence is ok if you can afford
to get close.

Necro- Through out a blood golem and then bone Spear/Spirit the hell outta them

Zon- Guided arrow is not considered elemental or phys damage, un-blockable
shoot and watch em fall

Azzy- I really dont play them much, but dragon flight seems to rock their socks

Druid- definatly use twister or armegeddon


Using one of these will allow you to bypass the phys immunity that the monster possesses

well i have a sorc and hen it hits immunities iswitch to pala learn zeal high level and it just flys threw those bad imutieis

Runeword Famine, Gimmershreds, Lacerator, Hellrack, Tiamat's Rebuke, Lavagouts, a weapon with a chance to cast Amplify Damage on striking, The Reaper's Toll on a merc, elemental damage charms, ...

Make a pure summon Druid. You'll think of many ways of handling PI monsters.

I would of thought that Berserk would have jumped to mind first?

Twister is physical damage for your information. So is Tornado.

absolutely berserk for barb
you can use concentrate too, but much slower ...

u spell horrible nightwish
