Questions

Hello,
i’m a new user of the Kali’s distribution, and i would know if there is a limit using these tools to the challenges ?
I would not get trouble just for trying some tools in the root-me environment.
Thanks for the answers.

As long as it’s allowed by the website, you are free to use them. I don’t think it’s a must-have to get past the 1k points (even if you still need to look for tools). However, if you want to go further (go above 3k) it’s pretty sure you might need them. (They are still not necessary, it’s just to make life easier)
