How far have you gotten in hardcore? I'd like this to be a thread where we talk about ways of beating the game! Do veterans have any tips for relatively new players?
Personally, my two hardcore characters are now just over level 80 and I've collected enough good gear and charms to make sure I always have +175 to all resistances in hell mode and I finally feel like I'm in a safe place to work towards beating the game, which for me is to solo Baal. After that I heard there are harder versions called "ubers" which I may try to work up to those eventually.
Also if you think the game should be changed in any way in the hardcore version it would be interesting to hear about other people's gaming philosophies.
