It's been too long since I did this! I describe a situation and you pick which edition would work best with it. WARNING: pony videos 
You're a high(ish) level magic user and your epic level mentor send you a new spell! It goes:
From one to another, another to one. A mark of one's destiny singled out alone, fulfilled.
You cast the spell and it turns everything wrong! All your best friends got their classes/profession/whatever changed! It's like turning a level 13 Fighter into a level 13 Wizard (but not letting the fighter respect feats, abilities, items, etc.). No one is happy about it...

It totally sucks, but you figured out how to fix it; with the power of friendship! By helping a friend, everypony rediscovered their natural talents!

That trial has inspired the high(ish) level magic user into fixing the spell that spell. It now goes:
From all of us together, together we are friends. With the marks of our destinies made one, there is magic without end.
With the support of a good group of friends, you can achieve great things!

With the spell rewritten, she finds herself transformed into a higher being, ready for epic level adventuring!

Okay, which edition(s) could best emulate the spells being described here? Also, which edition(s) could best emulate the process of fixing the broken spell? Or the process of having your destiny messed up so much? Your guess is as good as mine...
