So to any one who knows what a Tesla coil is, +1.

The bomb will start as a 2 star weapon that can be bought from brinx for 20(?) bark modules.

How this bomb will work is that the initial "detonation" will really do nothing on its own, BUT if you have another Tesla bomb within the radius of another then they will produce a electric chain causing a line of damage to be produced. Any enemy that enters this line of static will take damage every second, and possibly twice per second. The actual range of the Tesla be similar to how the mist bombs go, largest with 5, smallest with 2, ect.
After the bomb goes off the Tesla can stay their for 15 seconds ALONE but if it activates a chain with another Tesla is automatically will only have 5 seconds left in the timer before it falls apart regardless if it had 13 seconds left or 2.

Now for the three types. The Normal type can cause minor stun on the 5 star. The elemental type can cause minor shock on all. The shadow form.. I will talk about later.

I am not too sure about the damage scaling, I feel it should be similar to the DR in damage tbh.

Welp, might as well mention the shadow variation now. The shadow variation will only be able to crafted from the 5 star normal variation at well.. I guess what would be best described as a Swarm Pool. I have had the idea of the swarm functioning as a misunderstand villain.m providing the player with a way to craft a special weapon would at least imply this idea. THIS IS NOT 6*, it is simply a side craft into the Swarm Nikola.
If this is not possibru then maybe have it be a rare drop from devlites as a recipe for an upgrade from the 4 star normal variation.
