Only one time use.
Think of like world leaders, celebrities, ya know 😉. Are you gonna make them do some embarassing things, or illegal acts.

Take control of an NSA agent with access to the most powerful hacking tools, hack everyone’s phone, install a program that randomly have a popup at random intervals, the popup message says “I’m watching you”. This also tries to spread itself to any other phone it can connect to. Pure chaos 😈
Pretty sure I can do this in a minute, depending on how good the NSA tools are.
As someone with ADHD, I’d immediately get myself doing the things I want to be doing. Manipulating/screwing over others? No thanks. The havoc I wreak just in myself is plenty enough
Wouldn’t you just get distracted and put it off for later like you already do when you already have control of yourself albeit through the very same ADHD-addled brain you were hoping would for some reason spend the one, in some way supernatural minute, highly effectively?
