Tesla Coil
The Tesla Coil is a block that shoots electric bolts to any mob that gets close to it. It has a 10 block radius.
Obtaining
They can generate inside meteor dungeons.
Usage
Power Consumption
If you power your tesla coil with external power, batteries or generators for example, it will use up to 100k HEs per second.
If you place 
starmetal static electricity generators under it, the tesla coil will work without requiring external power.
Targeting
The Tesla Coil will try to target all entities in its 10 block radius.
It will deal less damage if there are many entities in its radius.
The electric bolts cannot go through blocks. This means that you can build a wall in front of you and the Tesla Coil, and the electric bolts cannot hit you.
Defence
You will not get electrocuted if you are wearing metal armor (steel, titanium, schrabidium, power armors, etc. but not CMB steel armor, or insulating armor like (leather and hazmat suits).
You can also block the electricity by building a wall in front of you.
Damage
The default damage per zap is 50% of the target's health (at least 1.5 hearts and at most 10) divided by the amount of targets being zapped. That means a large amount of players crossing the tesla coil at once will take barely any damage.
Notes
- Uses power constantly, even when not electrocuting.
- Useful in mob grinds and mob farming.
