**Crackling slag** is a passive item

## Effects

* Adds a chance to fire waves of fire which deal the same damage as Isaac's tear damage.
	+ Fire waves will spawn a flame on every tile traveled until it hits an obstacle or becomes too small. And each flame will damage enemies separately.
	+ The speed at which a fire wave shrinks depends on tear range.
		- Fire waves spawn at the same scale of the tear/weapon that spawned them.
		- A fire wave will shrink with 0.05 scale per flame spawned at Isaac's default range (6.5/260).
		- The rate of shrinking follows the following calculation: 0.325 / (TearRange/40)
		- TearRange is not equal to Isaac's range stat but it's API value instead. One range is equal to 40 TearRange.
	+ The chance to fire a fire wave depends on luck.
		- At base luck (0), it is 25%.
		- It maxes out at 40% with 15 luck.

## Notes

* Fire waves will spawn in addition to tears fired and will not replace them.
* Fire waves will inherit the scale and color of the tear/weapon that spawned it.
* Only 8 fire waves are allowed to be active at the same time. If the amount of waves is at or higher than this limit then no more waves will be spawned until some have dissapeared.
