Just a suggestion, but i was thinking sports themed weapons/gear. my first idea was a baseball set.

Helmet: catchers mask
Armor: jersey
shield: baseball glove
sword: baseball bat
gun: practice baseball launcher

i haven't come up with a bomb idea for baseball quite yet, but i had a couple ideas for american football

helmet: american football helmet
armor: american football torso
bomb: a football that is charged and placed on the ground. there is no actual explosion, but when it detonates, all enemies in range are forced into the center of the blast range for a moment and damaged by a barrage of football players attempting to get the ball

i know this concept is silly, but some of these ideas (not all though) could work

comments are appreciated
