Immovable Rod visual variations (#25932)

* Adds variations to immovable rod

* slash oopsie

* Changed prototypes from being hardcoded to being defined in the rules component

* Changed from 10% chance to 5%

* Changes based on feedback

* Fix nullable error

* Moved randomized logic to .yaml. Probabilities of alternate rods add up to 5%.
