I appreciate the constructive feedback, The changes and terms you put out seems doable on my part. ^^

I understand that the Subversive Activities or Sabotage functionality is a coin toss, but it should work most of the time and has a higher probability chance against an unprepared opponent or someone who is unlucky or in E rank luck. He displayed this feat in Fate Last Encore when he goes up against an unprepared roman emperor herself: Nero, able to cripple them with poison before they can advance. It just take a lot of prep time and understanding of his surroundings. Robin is a hunter afterall. 

As for the Golden rule, its just a saying on how wealthy the servant is or how much resources they have, Robin has rank E so basically He's just frugal with his resources and is [url=https://www.youtube.com/watch?v=gV7lz6wCcfM&ab_channel=Aerobro] able to financial recover [/url] if he ever needs some currency if goes broke [s]how? by stealing of course![/s]. Where as some lets say gilgamesh or dantes who has rank A has some buttload of disposable wealth and has rare items in their treasury. 

lastly the May King NP, I have to admit, its description [s]that i blantantly copy paste[/s] is a bit grandiose, its just the invisibility cloak from harry potter. but hey, its still lethal when the shot is unseen. https://www.youtube.com/watch?v=-Ge4rCsfKeY&ab_channel=wolf4500

but yes i don't see Robin one shotting any servant any time soon, [s]unless ofcourse if they have a stack of various poison then Robin's Yew Bow go brrrrr.[/s]
