Yup Baladir, I gain at least 5-6K gems every single one of those books with the free 360 passes. And that includes doing a completely free Test of Might or Silverhand trial that’s running that weekend (thanks to the book). And that also includes just 1 boss kill each run and getting the dice reward (not multiple to try for more gem rolls).
Slimeworms, it frankly sounds like you’re somewhat inactive if you haven’t gotten a single legendary since August (besides Mirt’s freebie). Heck once every month or 2 I even get a random legendary from my Free 4-hour chest. I ran probably about 400 free challenge runs in Lightfinger last weekend and likely rolled about 20 16’s, which is literally 5% of the 400 runs (1 out of 20). You’re either grossly exaggerating or are simply not playing a lot, sorry but I’m not buying it. Sure I may be slightly upset at what are likely some diminished rewards in the red chests, the quests, and various other areas, but let’s not delude ourselves - Ludia does give out completely free currency that most other games do not (as @Baladir stated) .
This is one of the only mobile games that you can literally be competitive without spending a single cent. I’ve gotten myself to levels 16-17, with a ton of amazing gear, a bunch of legendaries, able to beat many level 18/19 parties, and have not spent a dime. Also I have only been playing around 7-8 months. It is easily possible to farm gems and gold without losses.
Baladir is 100% right, if you’re still not happy after having unlimited free play wherever you liked last weekend, and didn’t stock up on gold and gems, then you’ll never be satisfied.
