Tombs of Terror and Dalaran Heist

I quit playing around Boomsday and just came back in time for DoD release. Will I get anything for fully completing these solo adventures or is it just not worth it? I have a solid hunter deck that I crafted, so this or more can I get more Rise of Shadows and Uldum stuff by doing these.

There are small card pack rewards for completing the adventure. However, these are only 3 per wing, whereas they cost 700 gold. Therefore, the opportunity cost of purchasing the whole adventure is 12 packs. (Purchasing with cash reduces this cost.)

Whether the adventure is worth that hit to your collection is up to you. For me, it was worth it as ranked play gets VERY repetitive, and I personally find hearthstone PvE as the best version of hearthstone. You might want to try the f2p adventures (Icecrown, Dungeon run, Monster Hunt, Boomsday project, and rumble run) to see if hearthstone PvE is worth it for you.

Does that reward for each wing of both adventures? I’ve completed the first wing of both. Can’t remember if I got a reward though lol. That’s why I’m asking. I get that there are 3 more wings in ToT (2100 gold to access). So would I get 9 more card packs for that (which has 900 gold value)? Same with the Dalaran, 4 wings to go (2800 gold vs 12 more packs?)

Yeah. 3 packs per wing + 2 exclusive card backs (one for doing all wings on normal, one for heroic).

These rewards are strictly worse than just buying packs in the store, so the adventure is entirely dependent on whether you like the adventure game mode, or whether you prefer standard.
