The Dark Blood is a mod that I thought of about a week ago. It's kind of rushed and was made with MCreator. I'm unable to do animations as I am very trash at doing so. Other than that enjoy!
A few things are in this mod.
NPC's: Crimson Kake, Minion Of Crimson, The Judge, The Watcher
Food: Heart Of Cthulhu, Cooked Heart Of Cthulhu, Soul Of The Damned, Heart Of Crimson Kake, Soul Of The Judge.
Materials: Bloodstone (Has Armor & Tools.), Dark Bloodstone (Has Armor & Tools), Eye Of Crimson Kake, Lung Of Crimson Kake, Heart Of Crimson Kake, The Dust Of The Corrupted.
Dimensions: The Dark Blood Dimension, The Foresaken.
Biomes: The Lost Souls Of The Damned, The Foreseen.
OverPowered Things Featured: Crimson Kake (NPC), The Dark Blood Nova Crystal, Dark Bloodstone (Armor & Tools Only.), The Nova Star, Scream Of Crimson, The Judge (NPC).
You can use this in a very public server BUT if you are the owner make sure nobody has access to these overpowered items. Only you should have The Dark Blood Nova Crystal. Nobody else to keep things safe.
How to make the Portal? I got you. Place Netherrack in the same way as a Nether Portal and use the igniter to light and activate the portal. BEWARE! The Minions of Crimson are everywhere! Do not hit them.
