AR Pierce from Eternal Bloodless Trophy can also reduce damage prevented. See example below.
Let us stay with the same 61% damage reduction we’ve built in this thread for this example. Now, we will face an opponent who has Eternal Bloodless Trophy with 19.6% AR Pierce.
Defiant = 1-0.25 = 0.75
This is a 25% damage reduction from defiant set
Armor = 1-(3538x1.75x1.6)/((3538x1.75x1.6)+(20x1000)) = 1-0.3312 = 0.6688
This is a 33.12% damage reduction from AR. Or a 5% difference on reduced damage vs bloodless trophy]
3538 = (1-0.196)x(1700+1700+1000) (warrior gear)
1.75 = Plagued at Rank 3 [1+25%x3 or 1.75]
1.60 = Battle Mage at Rank 3 [1+20%x3 or 1.6]
0.196 = AR Pierce bloodless trophy
Resist = 1-(270x1.375)/((270x1.375)+(20x100)) = 1-0.1566 = 0.8434
This is a 15.66% damage reduction from resists
270 = 170 + 100 (gear)
1.375 = Cerebral Vortex at rank 3 [1+12.5%x3 or 1.375]
Overall reduction would become;
1-(0.75x0.6688x0.8434) = ~ 57.7% Reduced Damage Versus Opponent Using Eternal Bloodless Trophy with 19.6% AR Pierce.
