Behavior<\/h4>\nThe Son of Arachna is found in a circular room with four giant eggs and many smaller blue eggs that spawn a type of spider when destroyed. When activated, it will spawn a number of [Epic Arachna Elements](\/wiki\/epic-arachna-element) that form a web of slowing threads, before attacking.\n\n
Phase 1<\/h4>\nThe 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).\n\n- 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%.\n- 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.\n- 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%.\n- 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.\n\nThe 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.<\/b> When an egg is destroyed, it will release a large number of the respectively colored Crawling Spiders.\n\nNote that the first egg can be destroyed without activating the boss if the player takes care to not get too close to it<\/i>, although the boss will immediately activate afterwards if that is the case.\n\nEvery 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.\n\n
Phase 2<\/h4>\nThe 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 Slowed.\n\n
Phase 3<\/h4>\nThe 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.\n\nThe Epic Arachna Elements will also start periodically using red threads that inflict armor piercing damage instead of Slowing players.\n\n
Phase 4<\/h4>\nThe Son of Arachna starts circling around the room at a much faster speed, 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.\n\nThe 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.\n\n
