chore: change timers to not use ptrs

add comments as to why logic may seem confusing.

Tested that Spider queen battle can be completed without crashing and that schooner can also be used without error

Lgtm.

Considering most entities will never use timers, would it be worth moving timers to a component? The entity class has quite a few members at this point, might be worth delegating some responsibility elsewhere. This would regardless be for a future PR.

Yes. That would be ideal to make this large class smaller, just a bigger change :)
