Stalker

you lie in wait for the perfect moment to strike. as an action, you can choose to stalk a target and watch their movements. when you stalk a target you get a +1 to any roll you make against that target, this bonus stacks with every time you stalk the person up to your proficiency bonus (example: if you have a proficiency bonus of +3 you can use an action to stalk said person up to three times, gaining a +3 bonus to a roll against them). when you use the bonus like this, the bonus is reduced by one every time to use it in this way. you can only stalk one person at a time and lose all bonuses for that person if you choose to stalk another or you take a long rest.
