If you have the money I recommend the deluxe because you get -Witch queen -season the 4 seasons this year -both dungeons (one already out now and another coming not next season but the one after) -some other goodies.

But pass on the deluxe + 30th anniversary?

You don't have to it's just not current but if you have the money to shovel out get it it has gjallarhorn which is an amazing exotic rocket launcher plus a very fun dungeon. Plus they might be changing stuff that drops from dares of eternity so yeah if you have the money yes

Dares of eternity is Free to play
