In the future it would be nice to have Pants/Leggings and Shoulder for more gear builds and possibilities. Also would help with Set items too.
The inventory screen could also be updated in this layout:
SHOULDERS [ ] HEAD [ ] AMULET [ ]
WEAPON [ ] TORSO [ ] OFF-HAND [ ]
RING [ ] LEGGINGS [ ] RING [ ]
BELT [ ] BOOTS [ ] RELIC [ ]
