It just doesn’t stop.
Want 2 short rests? Fuck you, pay me.
Want to respec? Fuck you, pay me.
Want to recruit Scratch? Fuck you, pay me.
That’s preposterous, WotC would never do anything like that! They’ll helpfully not even mention $ anywhere in the app, instead we’ll get Gold Pieces (gp), Electrum Pieces (ep), and Platinum Pieces (pp). If you log into D&DBeyond, you’ll get a daily 5 gp reward and if you complete your daily quests, you have the chance to unlock even more rewards (1 ep per quest). Every session you run or participate in gets you another reward, while every purchase of a digital-only DLC rulebook grants you further rewards.
Nevermind that it would take hundreds of daily logins and constant vigilance with daily quests to even be able to afford anything, they’ll helpfully provide the option to “level up” your account to instantly unlock rewards without having to go through all that trouble.
