Hey there!
I've decided that my character should have a thing that will make him unique. I made 3 things as the potential tools Felix would have. The one that will win in the poll will be the official one my character will have Because it should make my OC unique, I've been trying to make them as original as possible. Also, because Felix loves mining, the tools' theme also is mining (mainly).
These tools are:
A miner helmet with a flashlight. Helpful when exploring caves. Also protects the head.
A laser that shoots a green beam that penetrates everything but indestructible blocks and mirrors within 3 (or 5? Haven't decided that yet...) blocks. Useful in many situations.
A simple magic cube that works as an ore detector - when it detects an ore within 3 blocks from it, it magnetizes to it and changes the color according to the ore type.
