An Elf suffered effects thereof.
As his head started reeling,

When the handsome young centaur came ‘round.

Of a Dragon just as he spits!

Polymorphed men ‘mong the treetops
When accosted by thieves
With no tricks up his sleeves,
He would smile, and call for the copse!

‘Bout the time that he bested a dragon,
And to get more attention
He neglected to mention
That the dragon was carved on a flagon.

To placate his Lord for a time.

And kept wearing his head.
A lich in line save mime.

But the time that it takes for the Peeling.”

Never fights, but seduces opponents.
Their violence she’s quell
As if using a spell.

And here is another one to add (from Dragon Magazine issue 105, January 1986):
A clever young druid named Eve
Used magic, her foes to deceive.
When other spells were spent,
She'd change to an ent
To make like a tree, and leave.
