Getting roles like official rifter or subscribing to the Patreon is an aura boost

Farming aura and having people screenshot it is a show of aura. Screenshotting your own aura farming flicks is an aura loss. Making a swag ass edit doesn't count though because you are putting effort into your aura flick. Others making edits of you is an even bigger aura gain.

Events are a prime area to gain aura. Whether that be large events or the community night Walls/Siege Events. Excelling in these events is a massive aura gain. PVP, spleef, etc.

You can gift aura to others (at the loss of your own aura)
