Evil DMs keep two color-identical D4s, one with numbers up and an evil one with numbers down, and they’re the only D4s allowed on the table. When directed to roll a 1D4, it’s drawn blind and rolled. The hopeful see what they want before their faces give way to crestfall.

A fight to your death it is, then.

The triangular shape naturally draws our eyes to the pinnacle. Bottom-numbered D4 are evil and should be banned.
