Heh Ha .. I am mini old floating geezer with phyma and back problems.
BAM. Instant death no jitsu. Wahahahaha.
Kids these days, no respect.
"phyma" http://www.google.com/images?hl=en&q...w=1594&bih=911
From some quick google research I found that you can use certain minerals to adjust the acidity of water. So maybe you mix water with some of those earth minerals to lower the pH level, heat it up a bit, then Presto! Acid Steam.
Fire and Water Jutsu combined.
Water for the acid.
Fire to vapourise it.
Last time I heard, Water plus Earth gave Wood.
PS: Zetsu's awesome.
If it's not Isuzu-chan Mii~
Huh huh...wood.
But yeah, that makes the most sense to me. She has two Bloodline Limits. One for combining Fire and Earth Styles into Lava Style, one for combining Water and Fire Styles into Boil Style.
As she's not related to the First Hokage, she doesn't have the Bloodline Limit that would let her combine Earth and Water Styles into Wood Style.
I also noticed that other translations are calling the Tsuchikage's Particle Style "Dust Release". Possible Earth+Air Bloodline Limit?
