So any suggestions on IAP's for this game? There are so many. I would think the items, although nice are not really worth it. Do the IAPs ever go on sale (Android)?
You can forget about items, you will find WAY better ones by playing.
I would say....play a bit...you can play all the first campaign and see if you like the game....you will lose nothing.
If you do, imho, mandatory are the two additional regions/campaigns, each one with new monsters, quests, items, etc....
The Vampire and skeleton tiles add variability to the white quests, with new tiles and enemies; beware, they are pretty difficult so you may want to buy them when you are done with the first campaign (but I highly recommend them as well, especially if you like the game and want to play it for hours and hours looking for specific loot).
Other than that...only the extra characters (think miniatures) remain....just buy the ones that you think you can like, if any, each one comes with their own skills and items.
You can happily play for ages just with the four starters characters....it's up to you really.
It mimics the boardgame....you bought the base box...then extra adventures/tiles....then extra characters/enemies minis.
You will notice there is a gold iap as well. Forget about that, by the end of the campaign you will sit on a pile of gold and nowhere to spend it.
And yes....you can (and you will) be robbed in game (those are original events in the boardgame too).
Can't answer about the sale thing, as I'm not an Android user....actually I don't know if they ever were on sale on iOS too tbh.
PRO TIP: after you learnt about the game and played a bit, I guess on normal....be brave and start a new hardcore game, where every inventory slot and skill matters.
Especially after 5 black orcs ambushes in a row :D
