About this Mod
Overview
This is a Neoforged Minecraft mod intended for use with the Echo Sculk Dragon (https://www.curseforge.com/minecraft/mc-mods/echo-sculk-dragon-for-dragon-survival)
Despite this, you can use it anywhere you want, too. It adds a number of MobEffects that you can add with /effect or other methods.
List of MobEffects:
- sculkdragonutils:sculk_harmony - This suppresses vibrations of whatever the potency is, and below. In version 1.1, it also prevents sculk sensors from activating when you walk on them.
- sculkdragonutils:warden_harmony - This prevents the Warden from targeting whatever has it
- sculkdragonutils:sculk_sight - This adds the Sobel shader from the 1.9 SuperSecretSettings
- sculkdragonutils:reverberating - This is a dummy effect that does nothing, but Sculk Shriekers will apply it to nearby mobs. You can use this as a trigger or check for other things.
- sculkdragonutils:sculk_bloom (v1.1 only) - This makes kills worth below 50 exp (To exclude wither, ender dragon, and modded bosses) to spawn a sculk spreader if it's able to. Potency acts as a multiplier, with 10% added effect per level. This also gives you 2 food and 10% saturation on a kill, also modified by the potency.
List of Commands (v1.1 only):
/sculk-bloom - This is a command that triggers a sculk bloom (like from the sculk catalyst) at the specified location. Worldgen makes it spread farther and the generated shriekers can spawn the Warden.
Credits:
Code for the Sobel shader implementation is from the Goggles mod (https://modrinth.com/mod/goggles) by IceWasTaken
Also because the code is the same, it's unfortunately not compatible... I will potentially look into compatibility later.
