Hazardous Redstone
by derexXD
Hazardous Redstone is a Fabric mod that makes powered redstone components damage living entities that touch them, modeled on real-life electricity.
What it does
Redstone wire and redstone blocks become an electric hazard system. When a powered redstone network is exposed, any living entity that comes into contact with it takes damage. The amount depends on the power level of the block state: a stronger signal hurts more, while a redstone block always deals full damage. Some mobs resist the current more than others, following the same logic as real electricity, and iron golems are one example of a mob with that resistance.
The mod runs on the server alone, so players join without installing it. It is published for Fabric only, with a single build for 1.20.1, and the source code is open source under the MIT License. The author credits a BlockerLocker video as the inspiration for the idea, and the project's icon, a lightning bolt, was drawn by TheRealPizzaMan.
Key features
Shocking redstone wire
Exposed redstone wire and components shock any living entity that touches them, dealing damage on contact.
Damage scaled by power
The damage a redstone wire deals grows with its power level, so a weak signal shocks less than a strong one.
Full-damage redstone blocks
A redstone block always deals full damage to whatever touches it, regardless of signal strength.
Resistant mobs
Some animals and monsters resist electricity more than others, in line with real-life rules, so the effect varies by mob.
