Tips to improve your silver per hour when grinding – BDFoundry

If you have invested contribution into a node, you can then use energy to increase the node’s level. Increasing the node level does give a small Item Drop Rate buff but the buff is only applied 10% of the time. So it will only be applied every 10 mobs you kill. Investing in the Aakman node does not work for grinding in Aakman Temple/Hystria.
