Explaining Elicia's Frostbite Alchemy
Okay fellas I'm finally making a post explaining the science of Elicia Hughes' alchemy technique which currently appears in two of my fics (Satisfaction as well as Simple and Clean) so let's start this.
Quick shout out to @kaethefangirl for helping me work out some of this stuff and designing the transmutation circle below
Elicia's frostbite alchemy is an adaptation of Roy's flame alchemy, but whereas his has a triangle (three points for the three elements needed to make fire - oxygen heat fuel), her's has a pentagon (five points) for the five elements needed to make a glacier:
90% water
9% oxygen
1% hydrogen
0.1% carbon
0.01% nitrogen
Her alchemy can be used to create ice and mostly uses her own breath to do so, given the fact that breath is a mixture of oxygen and water molecules so she can form ice from thin air!
However, she is also a little freak (probably from losing her dad at a young age and attempting human transmutation to bring him back and then joining the military when that failed) so she also tends to freeze the blood in people's veins. Some of the chemical components of blood include hydrogen and oxygen, so her alchemy can be used to freeze blood.
Her alchemy is similarly activated to Roy's (another thing due to basing her technique off of his) and so subsequently she uses alchemy gloves with the transmutation circle from earlier on them. Although it is harder to snap with her left hand (automail) she has gloves for both hands.
Speaking of her automail, it's made in the same style as Briggs automail is so as not to freeze over (although if you've read enough of Satisfaction you'll know that didn't work when her alchemy backfired on her).
Being both fifteen years old and the inventor of this new type of alchemy, Elicia does find it hard to control so sometimes just does regular transmutations instead but she likes to try and impress her uncle Roy occasionally by using her new alchemy (he's still upset she tried human transmutation though).
And that's all I can think of for now! But if anyone has any more questions then my ask box is always open and I'd love to chat about it!
