Defining the Kindreds in Tunnels & Trolls - The Basics - Leprechauns

What exactly is a Leprechaun in Tunnels & Trolls?  Is it the "pot of gold at the end of the rainbow" little man in a green suit and a funny hat that talks with a brogue?  Not according to the artwork on page 25 of of the T&T 7.5e rulebook.  He stands about as high as a Hobb's shoulders, with a short beard and elvish ears.  So, to me this makes him closer to a gnome in appearance then a classic leprechaun of modern lore.

Leprechauns are one of the few races with a footnote (and the only one of the common kindreds to have such).  We are told that all leprechauns are wizards.  We are also told they have a natural Wink-Wing spell that they can do without any magical training... but as they are all wizards, aren't they all magically trained?  Oh, and the spell was moved from the core book to theCodex Incantatem - no idea why.  It is 4th level, so I guess the Leprechauns get to learn it early and for free.  It even costs them no WIZ points to cast it - it's totally free, but you won't know that until you read the spell description.

Stat-wise they take 1/2 hit to STR and and extra 50% to DEX, INT and LK.  Even with their hit to STR, they should still be able to tweak out decent combat adds if they want to.

Not sure how to tweak them.  Truth, I don't think they need any.  The free Wink-Wing spell is a great "get out of melee range free" card to play.  They make great scouts with it's use and should rarely find themselves cornered.  I think I've overlooked their sue in the past.  I need to make up for that.
