//for most perks that adust a modifier, you can simply say: when this is active, apply this modifier. when it's not, remove it.
//To make this more convenient, we've provided a means to do this automatically. You can also manually remove one of these if a perk dynamically
//changes, or update them to new values if your perk does that, too, or check if it exists if needed.
//To use these: put them in your code responsible for activating the perk.
//Like all variables, be aware that any changes to these will only exist for the lifetime of the perk, and that different types of perks have different lifespans
//for example, conditional perks have a lifespan as long as their parent creature - they are simply inactive when the creature doesn't mean the conditions for that
//perk. Standard perks and timed perks (aka status effects), meanwhile, only live as long as the creature has them - they are destroyed when the creature loses that
//perk.
//Thus, for any standard/timed perks, if you want an adjusted value on all subsequent times that perk is obtained, you'll need to store that data somewhere it will
//persist, (likely the extended creature data section) then reload it during construction. Meanwhile, if you only want a temporary effect on a conditional perk,
//handle this whenever you handle the enable and disable related checks.
