I would take an invisible blanket so nobody could see you.
An infinity picnic basket, which is filled with burgers, sandwiches, hot-dogs and crisps,  so you don’t ever starve.

A never-ending supply of coke, so you can always be full of fizz and energy.
A mobile shelter, so you can stay comfy and have a place to stay with a fluffy pillow to support your head.

A silver sword, which can slice a hole in time, allowing us to escape to the future

I would take, a blanket so no one can see you, food so you don’t starve, never ending coke, a pillow so you don’t hurt your head, shelter so you have a nice comfy place to stay for a night or few.
