Son of Arachna (Rev. 65)

Last updated: Exalt Version 1.3.0.0 (Dec 2020)

The Son of Arachna is the boss of The Crawling Depths.

The Realm Eye says:
Arachna birthed thousands of daughters in her den, but only her very first child was a male. At first, the spider queen took great pride in her son’s might, but he soon became a threat to the rest of her children. He was banished by his mother, left to fend for himself in the wild and create a family of his own.

Behavior

The Son of Arachna is found in a circular room with four giant eggs and many smaller blue eggs that spawn Crawling Spider Hatchlings when destroyed. When activated, it will spawn a number of Epic Arachna Elements that form a web of slowing threads, before attacking.

Phase 1

The Son of Arachna will loosely chase players, firing rings of green arrowheads and single fast green orbs that inflict Weak. Depending on how many of the four large eggs are active, the boss will gain additional attacks and status effects (with each egg displaying the respective status it gives the boss).

If the Green Egg is alive, the boss will fire additional spreads of Slowing green bullets, and will be permanently Speedy, increasing its movement speed by 50%.
If the Blue Egg is alive, the boss will fire additional rings of wavy blue shots that Quiet, and will be permanently Energized, letting it occasionally spawn large spider minions.
If the Silver Egg is alive, the boss will occasionally fire multi-directional parametric purple shots that inflict high damage and Expose, and will be permanently Armored, increasing its DEF by 50%.
If the Red Egg is alive, the boss will frequently fire additional 2-way shotguns of red Bleeding bullets, and will be permanently Damaging, making all its attacks pierce armor.

The boss is invulnerable until one of the four eggs is destroyed, upon which all other eggs will become invulnerable until later phases. However, a random one of the four eggs will always be covered in webs and invulnerable until the end of the fight. When an egg is destroyed, it will release a large number of the respectively colored Crawling Spiders.

Note that the first egg can be destroyed without activating the boss if the player takes care to not get too close to it, although the boss will immediately activate afterwards if that is the case.

Every time the boss loses 25% of its HP, it will change phases, go invincible, and expose the eggs again, meaning that an egg must be destroyed each phase to advance the fight. Which attacks it uses and which buffs it will have in each phase can be altered by managing the order in which the large eggs are destroyed, as well as randomly depending on which egg is invulnerable.

Phase 2

The Son of Arachna circles around the web while firing the above pattern, alternating between different orbit distances. The Epic Arachna Elements will also begin firing single aimed web shots that inflict Slow.

Phase 3

The Son of Arachna starts picking Arachna Elements at random and charging towards them, leaving a trail of Spider Stars in its wake. When reaching the web spoke, it will circle it briefly, rapidly firing green orbs, before moving to another random spoke. Its colored attacks will switch to radial spirals from this point onwards.

The Epic Arachna Elements will also start periodically using red threads that inflict armor piercing damage instead of Slowing players.

Phase 4

The Son of Arachna starts circling around the room, rapidly firing its radial attack and whatever colored attack it has left. It will periodically stop at the room’s corners to fire a dense spiral of green orbs.

The last egg, which was previously covered in webs, becomes uncovered and vulnerable. When its last egg is destroyed, it will start using its original firing pattern, chasing players if they’re too far but fleeing from them if they get too close.
