A copy of my Hipper Division Tank build, but optimised for Siegfried. You see, I did the math ;) Do note that just like on the Hipper build, Acoustic Chamber and Fixated are interchangeable depending on whether you want to play more offensive or defensive role in your division. Similarly, feel free to choose what fits your playstyle in the third modification slot. Note: This was done assuming that damage reduction is calculated multiplicatively, like concealment is. First of all, Siegfried's base hp is high enough that a maxed out Hyde will provide a greater hp boost than Sims: 55.000 + (400 * 7 = 2.800) = 57.800 55.00 * 1.06 = 58.300 Additionally, only from 46.668 Base HP does Hyde surpass Sims in effectiveness: 46.667 + (400 * 7 = 2.800) = 49.476 46.667 * 1.06 = 49.476 Next up is damage reduction (DR), were there's two options with inspirations: Hyde (6% HP) and Camponi (4% damage reduction), with the other DR sources being Vice Defence (16%), By the Book (20%) and Aegis (6%). Here I will be calculating effective HP for both options, both with and without By the Book active: With BtB: @Hyde: 58.300 / (0,84 * 0,80 * 0,94 = 0,631) = 92.293 effective HP. @Camponi: 55.000 / (0,84 * 0,80 * 0,94 * 0,96 = 0,601) = 90.697 Effective HP. Without BtB: @Hyde: 58.000 / (0,84 * 0,94 = 0,789) = 73.835 Effective HP. @Camponi: 55.000 / (0,84 * 0,94 * 0,96 = 0,758) = 72.557 Effective HP Even fires, which deal percentual damage based on max HP (18% per minute), do not make the Campoli build better at any point. For a tank build, Hyde/Sims + Sansonetti is the way to go.
