GM event racial potions
 

besides being a fun onetime trick, do these gnome, woodelf, and darkelf potions offer some quest/MQ utility? i am not knowledgeable in all things EQ, so please be kind :)

Try it and let us know!

Some ideas:
Stein of Moggok quest. :)
Turning in gnoll fangs in Qeynos
Turning in Crushbone belts in Kaladim
Seeing how you look as a Gnome or Dark Elf in a Guardian Robe, Robe of the Spring, or other unusual garment

There are probably some faction quests you could do if you really wanted to have a character that normally would have no way of become non-KOS. Iksars probably the most notable but also the race who generally doesn't care much about faction unless you rolled a warrior.

probably nothing wolf form doesn't do too tbh

Whatever you do, post screenshots.

so basically fashionquest... wolf form will do the same faction modifier?

basically the sole use is popping one to see how your guy looks in that illusion

First, no, wolf form is not the same thing as actually getting racial faction adjustments. Second, you can't use wolf form many zones, including some cities.

i guess it's possible there exists an obscure quest npc that's both indoors and can't be charmed or something
