Bad Effects

Looking for a simple way to make Minecraft more challenging? This mod might be exactly what you need.

Bad Effects adds various negative effects to the game that occur in everyday gameplay situations, making survival more realistic and difficult.

Main Features

Heatstroke - Being on fire for more than 5 seconds in a hot biome causes weakness and slowness or mining fatigue.

Broken Leg - Taking fall damage equal to or more than 1 heart applies slowness (duration increases based on damage taken). Damage equal to or more than 5 hearts additionally causes wither effect.

Lack of Oxygen - Staying above build limit longer than 5 seconds causes nausea, and longer than 10 seconds additionally causes wither effect.

Drowning - Taking drowning damage may randomly cause nausea.

Frostbite - Staying in a cold biome (including ocean and the End) for more than 1 minute without a heat source in hand or nearby causes hunger, and after 30 seconds deals frostbite damage every 5 seconds (damage increases over time).

Food Poisoning - Eaten food has a small chance to be bad and cause poison effect and nausea. Raw food has a higher chance of causing food poisoning.

Stuck - Suffocating in a wall has a small chance to cause mining fatigue.

Stun - Taking explosion damage causes slowness (duration increases based on damage taken). If you take equal to or more than 5 hearts damage, you additionally gain nausea.

Karma - Killing a villager or iron golem has a high chance to cause bad luck effect. While having bad luck effect, you may randomly get struck by lightning.

Additional Effects

Vision Disrupt - Taking magic damage randomly causes short blindness. This doesn't trigger if you have poison effect because poison damage is classified as magic damage.

Broken Hand - Breaking tree logs, glass or glass panes with bare hands may randomly hurt your hand. When breaking glass, additionally causes wither effect.

Infection - Taking cactus or berry bush damage may randomly cause poison effect. Wearing more armor decreases the trigger chance. Full armor set prevents the effect from cactus, while boots and leggings prevent it from berry bush.

Head Bump - Hitting your head against a wall while flying causes short blindness and nausea (nausea duration increases based on damage taken).

All effects can be disabled in the mod configuration.

Note: The mod works server-side (clients don't need to install it).
