Well why can't it be a gauntlet technique? The gauntlets give you the ability to mold fire in a firebending like ability

Plus, I don't see how Firebending is OP considering I could just be a victim of the range game. The sealing and absorbing is alright, my fire immmunity is just fire jutsu, minus amaterasu, anything else is fair game. My strategy against fire technique users will force them to go either in long range or taijutsu range which either way will prove good for me. I don't see how Firebending is OP, but I can agree with you on Fire Technique Sealing & absorbation. If you want, I'll willingly unlock abilities as the RP goes on, seeing as everyone is complaining.
