Welcome to Haruna's database where knowledge is free xD

What I know:
Wind and Fire is Scorch Release
Water and Wind is Ice Release
Crystal from a logical standpoint is from earth releas alone like how earth benders bend metal and crystal, I'm discounting lava on this.
Fire and Earth is Lava Release.

Lightning and Water from a standpoint is Storm Release.
I dunno about explosion release.
Blaze Release is solely an advanced form of Fire Release without a doubt.
