Siscu’s Survival Expansion Data Pack brings you an entirely new survival experience! Welcome to Survivor’s Elegy, an extensive data pack designed to add cohesiveness and interesting features to your survival world! With renewed Biomes and some mechanics, this data pack is worth your time! Enjoy playing this data pack!
Features:
Game Mechanics
- Withering: Overworld creatures staying in the nether for a long time will be affected the wither effect every ~1 minute! The withering can be mitigated by staying on other dimensions, which will gradually cure withered entities, or by eating warped wart food, which will extend the time of invulnerability. But beware! Eating too much of said food is not good, and you’ll start experimenting side effects if consumed recklessly.
- Zombifying: Creatures can be infected with the Phage effect, which will turn them into zombified versions of said creature or die if there’s no zombified equivalent. Players can be affected by this too, so watch out if you’re playing on multiplayer.
- Rotting: Considering Zombified creatures as well-functioning organisms isn’t exactly correct, hence why with this datapack they’ll rot until they’re just a sack of bones. By extension, this also adds new skeleton variants: Piglin Skeletons and Illager Skeletons!
- Updated Swamp Hut: Swamp Huts have been boring since they were added. This pack changes them so it’s a full-fledged house with multiple enemies and a vast amount of loot and information!
- New Nether Biomes
- And many more!
