The otherside is a dimension between life and death it is where entities go when they "poof" after being killed.

When you die you are sent to this dimension, if you die again you are sent back to the overworld to wander as a spirit for the rest of time

However, it is not impossible to escape this dimension it is rumoured that there is a totem that can send you home

Surviving in this dimension is difficult due to it being filled with the bodies of its previous victims all of which will attempt to give you the same fate they received

Using a Totem of Revival will send you back to your respawn point so there is still a reason to set your spawn at your base

Singleplayer

in singleplayer this mod acts as a hardcore mode with a chance to save yourself after death but if you die a second time within this dimension then you are trapped in spectator mode and cannot return

Multiplayer

While the mod works the same way in multiplayer, an extra totem becomes of use this totem can be traded from a master cleric and will revive All dead players, you can save your fallen friends but it will also bring back fallen enemies
