help on making advanced tutorials Options

[atlus]

Okay I need someone to tell me how to do a couple of things on the rpgmaker 2000 so that My project I'm starting on will be unique. Let's see there is a lot I want to know so going to start with the most important. Okay I'm planning on making an Item called a Time Sword and when equipped on the field or in battle he will transform into an older version of himself with different skills and different stats. The thing is I have no clue how to do such a thing. P.S The other events I'm thinking of is an morrowind style leveling system, enemies reinforcements that appear after a certain amount of turns, a MP System where weak spells take say 1 turn and stronger spells take more turns. There's more but that's the gist of it! (i hope I've improved in writing posts...)
