The user can expend aura to continously generate a "death radius" in which the surrounding opponents will be poisoned as long as they stay in the circle. The rate of the poison is slow at first but increases exponentially the longer someone stands in it. The effects of the poison do not go away if someone leaves the circle.

The drawback is range, perhaps 3-4 meters at most, the farther away the less effective, the continuous need for aura to fuel it, and the fact it will injure allies too.

I also had one for just a standard buff type semblance, basically I call it "wheelhouse" in that, in a radius, the user can apply a buff to either speed, strength, or endurance (although only one) to people they choose within range.

Finally is one where a user can constantly feed their aura to apply a sort of exponential buff to themselves for increased durability. It is slow going at first and requires a lot but grows stronger and eases up on the cost later on. I liken it to rolling a boulder up a hill and watching gain speed as it goes down the other side. So, battles of attrition can go the user's way quickly but if the fight is short-lived it can be a losing gamble.
