To start with I used Warrior lv10, 20. Then spellcaster lv30 until I picked my current one up on area 23 I think. Been autodueling with it since and yet to lose.
Come back once in a few hours and you stamina will be full. Since its summer and I have absolutely nothing to do, I open the app when I'm bored. Got to level 25 in 2 days
Just for the record. I purchased a large EX once. The rest is about timing the stamina to your level ups since leveling up fully replenishes your stamina. No point waiting for 30 stamina to fill when you only need 5 for the next level. I've only lost 2 dice battles and they were both in the infinite area. When you get 4 dice the chance of getting additional rolls increases substantially.
Been playing this event since it came out before and after work. Currently at level 25 myself and have not purchased any EX stamina. So it's definitely possible to get there, especially if unlike me you do not have to work. Either way, who cares if he purchased EX stamina, why so salty?
The irony is I was busy working too so I used the EX stamina to catch up on what I missed. I always get labelled p2w. I don't even play ranked anymore other than getting weekly missions and even then it's a kamikaze deck. I'm rookie 3 (3 wins by connection errors). I just enjoy collecting the cards and playing our own games with friends in my discord. None of this competitive meta nonsense.
Actually, the skipping the chests thing is actually REALLY good advice. They're mostly completely optional, and just eat up stamina. You can get them whenever, you don't miss anything by skipping them. Wait until you're done playing for the day and use the last bits of stamina you have on going back and grabbing them.
The chests in infinite area should be collected before defeating the boss, else you lose them(as the area will be resetted).
Collecting coins(and maybe very rare gems) is better from chests than from monster that require more than 4 times the amount of stamina.
Wait....how did he get to level 21? I've been playing this game and finished off the boss at area 15. And now I'm just stuck there waiting for more levels to arrive on the 7th.
So, you can't proceed further unless you pay? I thought this game wasn't supposed to be a pay to play....
