this mod allows players to join the Sculk Horde and spread the infestation via an Origin. it was pretty popular in the Team Peril discord, so I figured I'd upload it here. more Sculk Horde origins are planned.
Origin Description/Powers:
The Gravemind's latest innovation, Sculk Commanders help lead the Horde on its path to consume all.
One with the Sculk - You are a creature of Sculk. You are very vulnerable to certain items, but other Sculk mobs will not attack you.
Ours to Command - As a leader of the Horde, you may request reinforcements from the Gravemind periodically using nearby Sculk Summoners.
Emergency Measures - You have the ability to return a portion of your body to the Sculk, infesting nearby land and summoning additional creatures.
Home Field Advantage - You become healed and satiated when nearby infested blocks.
Synthetic - Your body does not function through normal means. You cannot eat or regenerate naturally.
Infest - Your attacks have a 10% chance to inflict Burrowed.
Harbinger - The Gravemind tracks your movement and may raid points of interest that you visit.
CONSUME. - You are prohibited from performing certain inefficient actions, such as breeding animals.
Unimpeded - You are immune to the Darkness effect, and Sculk Sensors do not detect you.
Feared - Villagers will refuse to interact with you, and Iron Golems attack you.
Impure Warding - A complicated system of wards decreases the duration of any applied Purity effect to 30 seconds.
