Have I already posted about this one?
I was granted a wish. A one use of the last level spell in AD&D. I asked for a super power, one which no ordinary creature could ever mimicry.
And hence, I was the only dwarf in all the realms of the real world’s RP’ing systems who could suck a sugar cane while simultaneously whistling a tune with my lips.
On another occasion I had a wish granted again, I tried being poetic. “I want the power of a thunderstorm in my voice”. I imagined I could get some nifty word of command/power/whatever you call it with this flick, but instead I got a 500 decibels (like, twice the rating for an airplane landing by your side I think)… burp. Yeah, I could permanently and irreversibly deafen enemies - and allies alike - and pop small creatures’ heads with the burst of my burp.
Now picture in your head, a squirrel being hit by such a powerful sound wave and its eardrums and eyes popping off. I didn’t immediately know what power I had, for the wish spell caster disappeared without telling me, so the squirrel thing is the description the GM gave me when I went and tried against my first moving target. Well, it could be useful after some creative tactics were added. I used it to kill some enemies who were hiding underwater in a lake once. Pretty cool.
By the way, if I’m not mistaken, there’s an arcane spell that does that too…
