Defense, Ubers and You! I play a Dragonslayer, almost every day; Iâ€™ve experimented with and used several sets of gear over multiple incarnations of the same character; always with the goal of doing Ubers faster and better. Lately Iâ€™ve been advising people to put their extra skill points in this build into Defiance, as the only Holy Shield synergy. Defiance because Blessed Aimâ€™s passive bonus goes unused with ITD weapons and Smite and with the proper setup we usually roll with 90 max LR, stacked to hell, with some absorb on top. â€œYou can never have too much defenseâ€ I say. Well the other day someone challenged that: â€œWhy put any points into Defiance when Exile allows for 25K+ defense already? Why even us that much? Why max Holy Shield past the point of ~30% block? If resists and Lifetap are all we need we should be maxing resists auras for a bunch of 95 max resists right?â€ These are the question I was running into and I admit I didnâ€™t know how to answer them. Well I decided to look into it.. Resists are very important during your standard Pandemonium event; Iâ€™m sure youâ€™re all aware of this. Even without max resist increases from gear you only take a fraction of the intended damage from elemental attacks, yet a lot of people assume all of the danger in Uber Tristram stems from spell damage and Mephistoâ€™s Conviction aura, this simply isnâ€™t true. The monster levels in Uber Tristram are very high, as are the Attack Ratings of both the minions and the Ubers themselves. I believe a lot of the danger of Uber Tristram comes from being hit irregularly with multiple physical attacks at once, not overwhelming elemental damage like most of us are prepared for. There are more sources of physical damage than there are of elemental damage, physical attacks are more frequent and have the potential to do more damage than elemental sources. Also, the chance for an Uber to hit you, even with what might otherwise be considered â€œgodlyâ€ defense is astoundingly high. Letâ€™s look at Uber Baal taking swings at you at 10000, 20000, 30000, 40000 and 50000 defense at levels 80, 85 and 90 (rounded to nearest hundredth). Level 80 Chance to hit at 10000 defense: 71.81% Chance to hit at 20000 defense: 52.05% Chance to hit at 30000 defense: 40.81% Chance to hit at 40000 defense: 33.57% Chance to hit at 50000 defense: 28.51% Level 85 Chance to hit at 10000 defense: 69.97% Chance to hit at 20000 defense: 50.71% Chance to hit at 30000 defense: 39.77% Chance to hit at 40000 defense: 32.71% Chance to hit at 50000 defense: 27.78% Level 90 Chance to hit at 10000 defense: 68.22% Chance to hit at 20000 defense: 49.44% Chance to hit at 30000 defense: 38.77% Chance to hit at 40000 defense: 31.89% Chance to hit at 50000 defense: 27.08% See the ~3% difference between levels 80 and 90? Simply leveling up doesnâ€™t improve your ability to mitigate damage enough. Even at extremely high defense ratings, at a moderate attack speed youâ€™re taking many times the amount of physical damage that youâ€™re used to or can prepare for; add in multiple sources of physical damage (albeit at a lower chance to hit) and you can be â€œone-roundedâ€ probably more often than you think. Because of highly diminishing returns it would take a level 99 character about 325,000 defense to bring Uber Baalâ€™s chance to hit to the minimum 5%. Obviously this isnâ€™t possible but it illustrates my point that one can never have too much defense. The difference then, and the answer to my friendâ€™s question, is that to not max Holy Shield and Defiance could cost cause you to be hit 20-30% more in Uber Tristram than you otherwise would, and I believe that being hit that much more is more dangerous than taking more elemental damage.
