Iberia: Hardcore Alchemy Edition is a fork of Iberia by Rock Hymas with changes with a focus on cross-mod compatibility.
Iberia: Hardcore Alchemy Edition, like Iberia, changes Minecraft respawn so you lose your spawn on death, but keep your world. By default, time is set to day on respawn, but you can disable this feature. There are other game mechanics in the same flavor, such as disabled health regeneration. The mod is highly configurable.
Full information about the differences from the original mod are available in the changelogs.
