Echoing Spire Boss Guide

For each boss we run a seeded 60-second simulation of the game's two separate offense loops. Boss skills are checked whenever they are ready; the first one that passes its cast chance fires. Auto-attacks keep their own timer at the boss archetype's real attack-speed rank (base delay 0.7s), interrupted only by attack-pause skills and spins that explicitly disable attacks. Damage is weighted by the boss's ATK or MATK at that tower floor's level, plus spawned follow-up attacks, projectile count, and each half-damage wave from lingering zones and spins. All attacks are assumed in range and all projectiles connect. An elemental skill keeps its own element; Neutral skills and auto-attacks use the boss's current weapon element. The element on a monster's page is defensive and does not automatically color its attacks, though temporary weapon endows are included. The displayed auto share makes the modeled swing contribution explicit. Hovering a boss opens its combat card: HP, ATK/MATK, DEF and MDEF (soft + flat), Hit, Flee, attack cadence and attributes, derived from the game's own stat formulas at that floor's level and boss rank — so they read higher than the numbers on the monster's own wiki page, which uses its base level. The Hit and Flee advice comes from the physical hit roll: a hit lands with chance Hit − Flee + 100, clamped to 5–100%. Magic never rolls against Flee, and a critical hit skips the roll entirely.
