Abilities

What this boss does

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

	Ability	Type	Effect	Response
Broodmother & Megapithecus
	Bite	melee	Gamma 180 baseBeta 320 baseAlpha 540 base	Behind an 80-armor saddle and a Daeodon heal aura, the line eats it. Bare-backed dinos melt.
	Web	ranged, slow		Slows whatever it lands on. It pins a melee line in place while the adds chew, which is what turns alpha.
	Acid Cone	ranged, DoT		A ranged acid cone, damage over time. Keep the rider moving off it.
	Taunt	melee	Gamma 260 baseBeta 520 baseAlpha 780 base	A heavier melee she throws now and then. Higher base than the bite, but rare enough that an armored line rides it out.
	Summon Araneos	summon		Feeds the fight. Our Megatheriums want the adds; every spider they kill stacks the insect-rage buff that carries the damage.
Megapithecus
	Smash	melee	Gamma 400 baseBeta 800 baseAlpha 1200 base	Straight melee from a giant ape. An armored saddle and a heal aura carry the rider, same as the spider.
	Rock Throw	ranged		Hurls a boulder past melee range. It reaches flyers and anyone who feels safe at distance.
	Summon Apes	summon		Calls in ape adds. Keep a melee line on them so they don't stack on the rider.

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.
