What this boss does

One row per attack. Effect is the number for the selected tier; response is one clause.

Guide

How you kill it

our call

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

The fight

This is a sandbox. Other stacks clear him. This is the line we recommend, and it is the one that cleared beta and our first alpha. Our gamma clear and a second alpha run used rexes with the same levels at about 10,560 health and 456% melee; those results are below too.

Bring this

19 Rexes and one Yutyrannus. That is 20 tames, exactly the arena cap. Each rex sits at about 33,370 health and 632% melee, with 1,680 stamina, 960 weight, and 14,400 food: level 266, imprinted to 100%, on an 80-armor saddle.
The Yutyrannus is the courage roar. Keep a rider on it and keep the roar cycling. On our alpha kill the courage buff was on about 90 percent of rex hits, and on beta nearly all of them. That is a damage and resistance buff on every rex in range, and it is what makes the rock throw survivable.
No healer. There is no Daeodon in this line and no in-fight healing; the arena cap goes to rexes and the roar. Every rex walks in at full health or it does not walk in.
For you: food, water, and a stack of Medical Brews. If you are not the one on the Yuty, bring a shotgun and put shells into him between repositions.

The fight

Before you summon, heal and feed every rex to full. This is the whole healing model; there is nothing to top them off once the fight starts.
Pull him and put both rex groups on attack-my-target on him. The rexes are the tank and the damage; there is no split.
Roar on cooldown. Keep the Yuty in range of the line and behind it, never in front of him.
About 100 seconds in he summons Monkey and Bigfoot adds. Do not chase them. Keep the rexes on him and let the adds come to the line; they die on the way in.
The rock throw is the alpha-maker. He winds up and it lands on whatever he is targeting, and nothing on your side outruns it. The answer is the health you brought and the roar: no rex goes in below full, and the roar stays up.

Why it holds

The rock throw is 2,400 raw on gamma, 3,600 on beta, and 4,800 on alpha, and the melee is 480, 960, and 1,440. Through the 80-armor saddles on the 33,370-health rexes the rock landed for about 830 a hit on beta and 1,260 on alpha, and the melee for about 120 and 190. Our kills: gamma in 105 seconds with the 10,560-health rexes, beta in 155 seconds with 0 losses, and alpha in 173 seconds with 17 rexes and the Yuty, because 2 rexes missed the arena teleport.

The wipe

Our second alpha run went in with the 10,560-health rexes, some of them at 81 percent health, and the courage buff on only about 64 percent of rex hits. The rock landed for about 1,070 a hit through the saddles. The Yutyrannus died at 154 seconds and all 19 rexes died between 180 and 223 seconds; he went down at 229 seconds with no tame left standing.

Beta forgives a short start. Alpha does not. Bring the 33,370-health line, heal and feed every rex to full before you summon, and keep the roar cycling.

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.
Target DPSWhat our lines delivered, boss HP over our kill time: about 1,707 a second on gamma (180,000 over 105 seconds, with the 10,560-health rexes), 2,560 on beta (396,000 over 155), and 3,123 on alpha (540,000 over 173, with 17 rexes). That is what we delivered, not the floor against the arena timer; bring at least that.
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.
Breeding targetsRex: about 33,370 health and 632% melee on the fight sheet, with 1,680 stamina, 960 weight, and 14,400 food, level 266 at 100% imprint, on an 80-armor saddle. Yutyrannus: whatever keeps the roar up. No healer; the 20th slot is the Yuty.
Theory notesThe alpha rock throw is 4,800 raw and lands for about 1,260 on our 80-armor, fully imprinted 33,370-health rexes. That is measured on the line, not derived; the armor formula above is the starting point, not the number. With no in-fight healing, every rock is permanent until the fight ends, which is why the line has to start full.

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. The one-line tribute commands chain GiveItem with a pipe; paste the whole line.
