Guide

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.
Admin commands

For server owners and single player

A date tag means we ran or read that line on our test server. A catalog tag means the line was built from our catalog data and was not run. GiveItem takes quantity, quality, then the blueprint flag.
