Big DIL bonus weekend starts tomorrow after your regular update time. 50% more DIL on most things, 100% bonus on mining claims.
Since the Fleet needs a big boost of DIL for the project upgrades, recommend everyone try and get some grinding time in! Voth Battlezone already pays out really well, so with a 50% bonus on top of that, that's the place to be to really clean up this weekend!
I have only just gotten back into the game after a year or so off. What are mining claims?
