Utility weapons.
Utility weapons would lock utility skills to that utility weapon but would unlock weapon skills to be changeable. Utility weapons would be like weapons where they could be swapped during combat also.
Heal items.
Heal items can be equipped like weapons and work like weapons where two heals can be swapped in combat instead of needing to get out of combat and increases the number of heals available anytime.
Specialization mechanic.
Each specialization has a second or third set of traits that can be used instead of the first set. These sets would have different traits but would follow the same theme of that specialization. This is an expansion of specializations.
