Asphyxiation

Bleed your enemies dry of air, keep them gasping for it as the light fades from their eyes. When you use this technique, you focus and concentrate on 1 creature you see. At the start of that creature's turn, they must make a Wisdom Saving Throw if they’re an airbender; if they aren't, they are instantly affected. Airbenders can repeat the saving throw at the start of each of their turns until they are cleared of the effect. However, if you use this technique on a non-airbender, they must land an attack against you with disadvantage to attempt to break your concentration. When a creature fails their saving throw or you are able to maintain concentration of Asphyxiation at the start of their turn, they take 1d10 force damage and have disadvantage on attacks and techniques. If they fail their saving throw or you are able to maintain concentration for 3 turns, they have disadvantage on saving throws as well. After 13 turns and beyond, they become incapacitated. For every and at the start of their turn that they fail the saving throw or you are able to maintain concentration, the damage is multiplied by 2 (i.e 2 turns 2d10, 3 turns 4d10 force damage etc.). A creature that dies by Asphyxiation doesn’t fall unconscious, they immediately die. This technique is considered a Mastered technique.
