Faster Movement and Actions Based on Health

[Reecitz]

I'm looking to add a perk where my character's movement and some of her actions are faster based on the state of her health . To be more specific:

 

- Actions that have a speed bonus equal to the current amount of health she has (100 for reference), which would be halved when wearing armor:

+ Movement 

+ Attacking 

+ Cooking 

+ Crafting 

+ Picking 

+ Harvesting 

- Some actions would instead be done instantly with full health, such as picking and harvesting

 

How would I go about coding this? I wouldn't even mind some form of template to add the actions to, in case there are other actions I could include that can be sped up or done instantly; I think even some boat-related actions can be altered in this way.
