Regarding the resistance, I wanted to write it to PM since it's off-topic, but I think it would be interesting for others as well because there isn't too many examples of calculating the resistance on Wiki. If I'm wrong though, it'll help me understand the math of it better. So, here it goes.

Death ward I + full Tolassian armor set + Blessed Necklace + Nivarian Cloak + Ring of DW + Greater Ring of DW = 167 res to Death (I'm not including Personality bonus here, but my PER is 4). 167 res = (50/1)% + (30/2)% + (30/3)% + ((167-50-30-30)/4)% = (50 + 15 + 10 + 14.25)% = 89.25%. So, 10.75% of damage gets through, rounded down to nearest integer.

If I had the 2nd GRoDW instead, I'd have 177 res = (50 + 15 + 10 + 16.75)% = 91.75% leaving 8.25% of damage to come through rounded down to nearest integer.

Now, without rounding, I'd be reducing my incoming damage by exactly further 2.25%, which is relative to 10.75% is another (2.25/10.75)*100% = 20.9% reduction of the incoming, although already greatly decreased, damage. That's what I was talking about.

Now, with rounding, let's say we're getting attacked by a Varannari Witch (normal difficulty), who does on avarage 19 Death damage. With 167 res I'll take int(19*0.1075) = 2 damage. With 177 res I'll take int(19*0.0825) = 1 damage. That's twice is little. Now you may say that give or take 1 damage doesn't matter but what if you're swarmed? The difference will quickly add up. So that's why I'm saying it's not so pointless perhaps.
