I got my copy on saturday, and converted all of my previous characters over. I also created an Assassin (which I’ve only played multi-player with my room-mate’s druid - both are now around level 9) and a Druid, which I’ve gotten up to about level 10.
My observations, first about a couple of the changes made:
Monster Immunities:
These suck. Well, actually, these suck in the sense that they make the game more difficult They also make specialty mage-types (e.g., sorceress) impractical. I have a level 56 Ice Sorceress. Immediately after converting her, I took her into Act I in Hell difficulty. She was killed. By Zombies. Zombies! Turns out, they are immune to cold. Isn’t that lovely? I shudder to think what the Chaos Sanctuary mages are tricked out with now…
Having said that, my Charge-Bolt Sorceress is pretty much walking through Act V in Normal difficulty. The fact that they changed Lightning Mastery to increase damage rather than decrease mana costs has much to do with that. Of course, it’s just a matter of time until she encounters a Lightning Immune creature. That will suck.
Poison:
Poison is now a viable method of killing things. I have a high-level (mid 50s) Necromancer that I used to test out things like Poison Nova (he was one of my first characters, so his skill development wasn’t planned out before-hand; as a result, he has all available necro skills) - with greatly increased damage and a time-interval of only 2 seconds, it only takes a couple of blasts in Hell difficulty to drop Act I beasties. I like it!
As for new stuff, the Assassin is very cool. I haven’t messed around with the traps yet, so I don’t know how well they work. As for the single-shot kill that saepiroth mentioned, it won’t happen. You need to hit a creature three times to build up those charges first, then a fourth time to release the charges (whether with a normal strike or one of the Finishing Moves). Granted, it will do a lot of damage, but it will still take 4 hits to get there. And, you have to take Tiger Strike up to 20th level to get that 1440% damage bonus. Certainly no worse than Corpse Explosion, which can take most things out with only two castings.
My druid is concentrating on Bear stuff. So, he’s going to do the Werebear thing, as well as work towards summoning a really nasty Grizzly when he hits level 30. I’m not worrying about the Elemental skills this go around.
The socketing of items is pretty cool, too. The aforementioned Charge-Bolt sorceress has a Wall of the Eyeless, which among other things, gives +5 mana/kill. She found a rune which gives +2 mana/kill. One of the Act V quest rewards allows you to add a socket to any item, so she added one to the Wall, and popped the rune into it. She has to work very hard to run out mana now.
