Basically, for Normal-Mode Diablo :
* You had better have at least 75% Fire and Lightening resistance. Any less than that and his Fire Nova can hurt you badly (probably not an insta-gib, but badly enough that another clean hit would kill you).
* If he lands a clean hit on you (whether or not you have 75%+ fire resist) with his Flamestrike,
you die. (Instantly.) (Which, by the way, makes fighting him as an ordinarily-geared melee character, completely suicidal. I have had Barbarians with 2,800 hit points and 77% Fire Resist, plus a little Fire Absorb, 1-shotted by this Flamestrike.)
* If he lands a clean hit on you (again, assuming you have max normal resist) with his Pink Hose of Lightening Death, you MAY survive for a second, but not more than that. (This attack is lethal if you are standing too close to Diablo when he uses it, but it can be survived if you are only hit by the far end of it.)
* If he Bone Prisons you and you don't INSTANTLY teleport away (switch weapons to Pax Mystica staff and Blink), you will be Flamestriked,
you die.
The best strategy is to first throw a town portal near his central area (he seems to waste Bone Prisons on TPs in that area, a lot) and run around the central area, taking pot shots at him but NEVER staying in one spot more than a second at a time. (You stand still, you will be Flamestriked, you die.) Eventually you should be able to whittle him down, but don't forget that when you chug a healing potion, it temporarily impedes your movement speed, which can be fatal if it slows you down enough for Diablo to catch up to you.
Think we're done yet? Not on your (short) life. Just WAIT until you encounter Nightmare or Hell, Median Diablo. They have millions of hit points, do unbelievable amounts of damage very quickly, and can easily 1-shot all but the most well-geared characters, who are managed by a very experienced and attentive human player. That's Median for you, my friend.
