Questions and requests for help

[mythica_master]

Sorry if the following is a question obvious to anyone who isn't new to all this (like I am), but how would I go about making an item with special abilities? For example:

* A sword that creates a healing potion after each battle

* Armor that turns the wearer invisible

* A shield that casts a spell in combat by itself
Another question: How do I make more stats for characters? I'm talking like in DnD, where you have not only Strength, but Dexterity, Constitution, Intelligence, Wisdom, & Charisma. Getting these into my game (if there is a way) would greatly help me make the game more fun.
