Status Effects
Several status effects are used in DeceasedCraft, given that it is a modpack. The following covers status effects that you may encounter during a playthrough.
Grace
Grace is provided to a player each time they spawn into the world. As such, each time a player dies in their world, they will be respawned with Grace enabled. Grace has a 5-minute window, giving players some freedom in finding materials and/or retracing their steps to their body to collect their materials while NOT triggering a horde building.
Mutagen Sickness
Mutagen Sickness originates from the Mutationcraft mod. This is only transmitted via "assimilated" zombies, which cover most vanilla Minecraft mobs in their variants. Assimilated zombies can be spotted with grotesque features, often sporting spider-like appendages, expanded jaws, split heads with other body parts coming out, etc. Mutagen Sickness has a 5-minute window and is simply a flag to notify the player that should they die in that time frame, their death will spawn an Assimilated Player zombie. This is generally undesirable due to assimilated creatures having higher damage output and being able to infect other mobs (including zombies) in their vicinity.
If the player is still alive after the 5-minute window with Mutagen Sickness, the status effect will be removed with no repercussions.
