Guild Wars 2

The wiki is still playing catch up with the expansion, so I am having a hard time tracking down the info I want.

I know that there is a guy in the Guild Initiative that lets you exchange Influence for Favor. We no longer have enough to use that service.

We just finished our Mine, and there is a miner who allows you to exchange Influence for Aetherium Production boosts.

Are there any other sources of Influence expenditure?

Not that we know of

You can purchase Resonance after you unlock the workshop. That blasts through upgrades.
