The **Crystal Worm Father** is an [event boss](/wiki/quest-monsters#event) that drops the entrance to the [Fungal Cavern](/wiki/fungal-cavern). In the dungeon itself, it also makes a return to assist the [Crystal Worm Mother](/wiki/crystal-worm-mother). {{template-realm-eye-lore | response=The entrance to the abandoned dwarven mines was blocked off by the dwarves when they retreated. At the time, the mushroom tribes were appeased once the miners left.
Once Steamhammer realized how much valuable equipment had been deserted, he insisted on tearing down the barrier and reclaiming their property.
This ill-advised decision was quickly noticed by the mushroom tribes. Determined to keep people away for good, they have poured into the realm to keep wanderers far from the entrance. }}

Behavior

#####Event Version The Crystal Worm Father emerges in the center of the Fungal setpiece once four waves of mushroom enemies have been defeated. Immediately after spawning, it will summon a random Cavecrawler worm ([Leech](/wiki/cavecrawler-leech), [Maggot](/wiki/cavecrawler-maggot), [Glowworm](/wiki/cavecrawler-glowworm)). Once the worm is killed, it will become vulnerable, attacking with a flowering barrage of extremely damaging crystal shards that return to it. At half health, it permanently gains the Armored condition (resulting in 80 DEF) and adds in rapid 3-way shotguns of purple crystals. At about 20% HP, the Worm Father stops firing white shards (purple shards will still be fired), goes invulnerable, and spawns two [Death Morels](/wiki/death-morel) around the arena, which fire radial blasts. The Worm Father cannot be harmed until all Death Morels have been killed. When all of the Death Morels are dead, the Worm Father becomes vulnerable and resumes its attack pattern from before. It will also try to spawn more Death Morels near players. When brought to critical HP, the Worm Father retreats into the ground, leaving its loot behind. A portal to the [Fungal Cavern](/wiki/fungal-cavern) will open behind it right afterwards. #####Dungeon Version The Worm Father appears in the center of the [Crystal Worm Mother's](/wiki/crystal-worm-mother) arena when the boss reaches a certain phase. While the Worm Mother circles the arena and fires, the Worm Father will attack with an omnidirectional barrage of crystal shards. At half health, it adds in aimed shotguns of purple shards. The boss is permanently Armored, giving it 80 DEF. When brought to critical HP, the Worm Father retreats into the ground, resuming the fight with the boss proper. ####Reproduction Spawns (Event version):
