I$$m going to help you:

Create an Object class

Create a player and monster class that inherits from object

Player gets Spell points and Heal costs $2$SP

Monster gets an AC based upon its type.

create an item class.

You get to:

Create some operator overloads:

$<<$ for the Object class $($same as printObject function$)$

$<<$ for the Item class $($same as printItem function$)$

$<$ for the Item class $($compares bonus values$)$

$+=$ for the Item class $($adds bonus values and an int and returns an int$)$
