Hi, i'm relatively poor in HS, i have around 50% of the basic card, and nothing from the expansion Goblins vs Gnomes. my question is: how much can i make gold per day and buy booster ? Thanks!
It all depends on your quest. You can make 100 per day from daily wins which will be enough to buy a booster, and then you can set aside your quest rewards to buy expansions. I personally just focused on powering through the expansions and saved up all my gold. I got around 1 expansion every 5 days.
I have no idea about Arena, but as for constructed: 100 gold from 30 wins + quest = 140-160 gold per day. Make sure you have completed all the hidden quests of HS as well, you can find a list of them here: http://hearthstone.gamepedia.com/Quest#Unique_quests
Malboyoo, The direct answer is you can make a minimum of 140g (as stated above). Thus you can buy a booster yes. Shuvit also pointed out a great tip for further gold. Thumbs up!
