As Dark_Pyrro pointed out, that's a tall order. I would say, start out with a Bash Bunny, a Rubber Ducky, depending on what your equipment is, some O.MG cables, and a O.MG prorammer. And, Payload Studio Pro is worth the money.
if you're into wifi, get a good alpha wireless card, and you're good.
But, this gear is not a magic bullet, it won't help you to get that sweet shell.
For that, look into powershell, Python, and other programming languages.
read books on pentesting, look at youtube. This type of gear, will only be of any help to you, if you know programming, Av evasion and stuff like that.
You need to know the ins and outs of the platform you're targeting, it's defenses and weaknesses, that's the only way.
BTW, Learn Linux, you'll need it š
And, when you're done, look into a ProxMark3, a Flipper Zero, and a HackRF One, for some fun with software defined radio, and RFID.
For good measure, throw in some lockpicking (always fun to do over a cup of tea and some Netflix š )
Much Happy Hacking
