How you kill it

our call

Written from fights on this cluster, with the numbers worked out below.

Theorycrafting

The math behind these numbers, from our own fights.

DPS floorHP ÷ timer = the damage per second that kills the boss with zero seconds spare.
Your lineN × creature × melee = what a line of N delivers at the melee you bred, from the creature's base damage and attack rate.
Their hit on youhit × 100 ÷ (100 + armor) = damage through a saddle at that armor.
