You may be tempted to drive deep into the new Delve crushing foes until the foes are too uncrushable to be crushed any longer. Just remember that the Delve Level you reach will stick like glue in your normal Delve life.
Don’t be like me…or do be like me depending on whether you want this…I Delved deep in the last event with the All-Seeing Eyeballs and now I have a Faction that is really difficult to play, and as such won’t ever be played again with my limited 3 Delves per day.
Unless I use Ragnagord. (Not even then.)
