jMost everyone in the pods are wearing gear. After all it's not a jail cell, it's an incubation chamber. There are no bars it's a psionically enhanced prison created to allow mind flayers to impregnate you easier, they didn't care you had gear on, or off it seems. After all they can just take over your mind, control your body. Resistance is futile!

yeah maybe in character creation you can have an equipment tab. Where you choose your starting armor per 5e rules (sadly no plate armor for my wee lil darf), and a starting weapon. Wizards though don't need that stuff.
