How the math works
Total HP = Base HP x Iron Soul passive (1.5x). Damage Reduction uses a logarithmic curve: DR = 100 - 100 / (1 + (DEF + Rune) / 250). Effective HP = Total HP / (1 - DR). Buff Uptime = 10 / (10 + max(2, 15 x (1 - CDR))) per cycle. The verdict compares Boss Ult Damage against Downtime EHP and Active EHP.
